The coordinates of point B =(5,10)
what is coordinates?
Coordinates are a set of values which helps to show the exact position of a point in the coordinates plane.
step - by - step explanation
5-2 = 3
2-3= -1 = the x coordinate of B
-7-3= -10
-7-10 = -13 = the y coordinate of B
(-1, -13) is the point B
A is 3 to the right of the midpoint ,so B is 5 to the left to the midpoint
A is 10 up from the midpoint so B is 10 down from the midpoint.
so the coordinates of point B is (5,10)

Consider the rectangle with width 20 in and length 26 in, write a ratio of the width to length
The ratio of the width of the rectangle to the length of the rectangle is 10/13
We are provided with the rectangle. The dimensions of the rectangle are mentioned below;
Width of rectangle = 20
Length of rectangle = 26
We were asked to calculate the ratio of width of the rectangle to the length of the rectangle. So, to calculate the ratio of width of the rectangle to the length of the rectangle we need to divide the width of rectangle to the length of the rectangle as mentioned below;
( Width of rectangle/Length of rectangle ) = 20 / 26
( Width of rectangle/Length of rectangle ) = 10/13
So, we can finally conclude that the ratio of width of the rectangle to the length of the rectangle is 10/13 .

If you roll a die, find the probability that you: (Enter your answers in exact form or round to 3 decimalplaces.)(a) roll at least 4 or an odd number,Answer:(b) roll an even number or a number at most 5.Answer:
A.
The question asks us to find the probability of getting at least 4 or an odd number after throwing a die.
This is easily gotten using the OR probability of two events which states:
[tex]\begin{gathered} P(A\text{ OR B) = P(A) + P(B) - P(A AND B)} \\ \text{if A = rolling at least 4} \\ B\text{ = rolling odd number,} \\ \\ P(\text{rolling at least 4 OR rolling odd number) = } \\ P(\text{at least 4) + P(odd number) - P(at least 4 AND odd number)} \end{gathered}[/tex]To get at least 4, it means the possible values we can have are: 4, 5, 6.
To get an odd number, it means the possible values we can have are: 1, 3, 5.
From both set of possibilities, 5 is common. We need to subtract the probability of getting a 5 in both situations to prevent duplication.
Thus, we can compute each probability:
[tex]\begin{gathered} P(any\text{ number)= }\frac{1}{6} \\ \\ P(at\text{ least 4)= P(4) OR P(5) OR P(6) = P(4) + P(5) +P(6)} \\ \therefore P(at\text{ least 4)= }\frac{1}{6}+\frac{1}{6}+\frac{1}{6}=\frac{3}{6} \\ \\ P(\text{odd number) = P(1) OR P(3) OR P(5) = P(1)+P(3)+P(5)} \\ \therefore P(\text{odd number)= }\frac{1}{6}+\frac{1}{6}+\frac{1}{6}=\frac{3}{6} \\ \\ P(\text{at least 4 AND odd number) = }\frac{1}{6} \\ \\ \\ \therefore P(\text{at least 4 or odd number)=}\frac{3}{6}+\frac{3}{6}-\frac{1}{6}=\frac{5}{6} \end{gathered}[/tex]Therefore, the probability of getting at least 4 or an odd number is 5/6
B:
This part of the question asks us to find the probability of rolling an even number or a number at most 5.
We, once again, take a look at the possibilities to solve this question.
Possibilities of getting an even number are: 2, 4, or 6
Possibilities of getting at most 5 are: 1, 2 , 3, 4, 5.
Therefore, we can compute the probabilities as:

Luna purchased a computer at the list price of ₱56,000, less 30% and 20%. How much must Luna pay for the computer?
There are two disccount applied to this computer, the first one is 30%. To calculate its value, we need to multiply the original price by the fraction that represents 30%
[tex]\text{discount}1=56000\cdot\frac{30}{100}=16800[/tex]The first discount was 16,800. To determine the price after this, we need to subtract the listed price by the discount 1, this is done below:
[tex]\text{price}2=56000-16800=39200[/tex]Then we need to calculate the second discount, which was equal to 20%.
[tex]\begin{gathered} \text{discount}2=39200\cdot\frac{20}{100}=7840 \\ \end{gathered}[/tex]The final price is the subtraction between the price 2 and the discount 2, we have:
[tex]\text{ final price}=39200-7840=31360[/tex]The final price is 31,360.
Write an algebraic expression as indicated. The algebraic expression for the mountain Roberto‘s other account is
We have here that Roberto has a total of $3300 in two savings account.
Then, if y represents the amount in one account, we have that the sum of both accounts is up to $3300.
We can suppose that the other account is x. Then, we have:
[tex]x+y=\$3300[/tex]If we subtract y from both sides of the equation, we have:
[tex]x+y-y=\$3300-y\Rightarrow x=\$3300-y[/tex]Therefore, the algebraic expression for the amount in Roberto's other account is (since x is not mentioned, we have):
[tex]\$3300-y[/tex]In summary, the amount in Roberto's other account is $3300 - y.
9 Ron's family plans to add a new room to their house. They initially planned the width and the length of the room to be 10 feet and 25 feet. Now they want to add to the width. The amount they want to add to the width is shown by the variable I. 25 101 + Ron thinks that the area of the room will be 250 + 257. Is he correct? Why or why not? Select all that apply. A Yes, because the area of the room is the sum of 25.10 and 25r. No, because the area of the room is the sum of 25 . 10 and I. No, because the area of the room is the product of 25 + 10 and 25.1. D Yes, because the area of the room is the product of 25 and 10+ I.
The room is a rectangle with dimensions 25 and x + 10. The area of a rectangle is the product of its dimensions, so the area will be:
[tex]25\cdot(x+10)[/tex]We have to add the parenthesis because we first need to add 10 and x and then multiply. Distributing the 25, we have:
[tex]25\cdot(x+10)=25\cdot x+25\cdot10=25x+250=250+25x[/tex]As we can see, this matches what Ron thinks the area will be, so he is correct. Thus, the answer is "Yes". The why can be both because the area is the sum of 25*10 and 25x and because the area is the product of 25 and 10 + x.
So, the correct alternatives are A and D.

4. A student asks, “If the average income of 10 people is $10,000 and one person gets a raise of $10,000, is the median or the mean changed and, if so, by how much?
Since we don't know the specific income of each person in the sample, we don't know for sure if the median will change. Nevertheless, the mean will surely raise.
Since the current average income is $10,000, if one of them gets a raise of $10,000, then the sum of all incomes would be $100,000+$10,000=$110,000. And the new average income will be:
[tex]\frac{110,000}{10}=11,000[/tex]Then, the mean increases by $1,000, and we can't say anything about the median.
One way to determine whether a number is prime or composite is by creating a factor table.
Complete the factor table and the sentences below about the number 18.
The conclusion from the factor table of 18 is that, 18 is not a prime number i.e. it is composite
How to determine the factor table?From the question, the number is given as
Number = 18
The factors of 18 are represented as
Factors of 18 = 1, 2, 3, 6, 9 and 18
When these factors are picked in pairs, we have the following representations
Factors pairs of 18 = (1, 18), (2, 9), (3, 6)

The equation of the line that passes through the points ( -3,18 ) and ( 2,-7 ) is f(x) = -5x + 3.
What is the equation of line passing through the given points?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the data in the question;
Point 1( -3,18 )
x₁ = -3y₁ = 18Point 2( 2, -7 )
x₂ = 2y₂ = -7First, we find the slope of the line.
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
m = ( -7 - 18 ) / ( 2 - (-3) )
m = ( -25 ) / ( 2 + 3 )
m = ( -25 ) / ( 5 )
m = -5
Next, next we find the y-intercept
y = mx + b
18 = (-5)(-3) + b
18 = 15 + b
b = 18 - 15
b = 3
Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.
y = mx + b
y = (-5)x + 3
y = -5x + 3
Therefore, the equation of the line is y = -5x + 3

What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
Let's represent the number of days by x and the number of words by y.
At day 1 (x = 1) ⇒ Number of words (y = 200)
At day 1 (x = 2) ⇒ Number of words (y = 230)
The point-slope form of a linear equation is given as,
y = mx + c
Where m is the slope, while c is the y-intercept.
Substitute,(1,200) in y = mx + c
200 = m(1) + c
Now slope m = (230 - 200)/(2 - 1) = 30
200 = 30(1) + c
c = 170
Therefore, the equation become,
y = 30x + 170
The number of words after 8 days will be,
y = 30(8) + 170 = 410
Hence "The linear equation in point-slope form of the given condition is y = 30x + 170. The number of words after 8 days will be 410".

Graph a line with a slope of2that contains the point (-3,5).5
We will investigate how to graph a straight line on cartesian coordinate plane.
All equations of straight line are expressed in a general slope-intercept form as follows:
[tex]y\text{ = m}\cdot x\text{ + c}[/tex]Where,
[tex]\begin{gathered} m\colon\text{ slope} \\ c\colon\text{ y-intercept} \end{gathered}[/tex]To graph any straight line we need the equation of the straight line or atleast two points that must lie on the line.
We are given the slope ( m ) and one of the points that lie on the line as follows:
[tex]\begin{gathered} m\text{ = -}\frac{2}{5} \\ \\ (\text{ -3 , 5 )} \end{gathered}[/tex]We need one another point that lies on the line to plot the graph of a straight line. To find another point we must completely express the equation of the straight line ( general form given above ).
We see that an equation of a straight line is defined by two parameters i.e ( m and c ). We are given the value of the slope ( m ). We will go ahead and plug it into the general slope-intercept form given above:
[tex]y\text{ = -}\frac{2}{5}\cdot x\text{ + c}[/tex]Now to determine the value of parameter ( c ) we must have atleast one point that lies on the line. We will use the point given to us and plug in the respective coordinates in the equation developed above and solve for ( c ) as follows:
[tex]\begin{gathered} (\text{ x , y ) }\to\text{ ( -3 , 5 )} \\ \\ 5\text{ = -}\frac{2}{5}\cdot(-3)\text{ + c} \\ \\ 5\text{ = }\frac{5c\text{ + 6}}{5} \\ \\ 25\text{ = 6 + 5c} \\ \\ c\text{ = }\frac{19}{5} \end{gathered}[/tex]We will go ahead and update the equation of the straight line as follows:
[tex]y\text{ = -}\frac{2}{5}\cdot x+\frac{19}{5}[/tex]Now to get one more point to graph the plot we will assume any value of the for either variable ( x or y ) and then determine the value of the other variable as follows:
[tex]\begin{gathered} x\text{ = 2} \\ \\ y\text{ = -}\frac{2}{5}\cdot(2)\text{ +}\frac{19}{5} \\ \\ y\text{ = }\frac{-4+19}{5} \\ \\ y\text{ = }\frac{-15}{5} \\ \\ y\text{ = -3} \end{gathered}[/tex]Therefore, we have the two points to plot the graph as follows:
[tex](\text{ -3 , 5 ) \& ( 2 , -3 )}[/tex]We can go ahead and select the above points on the given grid to construct the straight line!
