Find the slope of the line that passes through the points (1,3) and (5,5).
Answer:
The slope is 1/2
Step-by-step explanation:
y²-y¹/x²-x¹
=5-3/5-1
=2/4
=1/2
Step-by-step explanation:
The best way to solve these is by making them into a equation, rise over run, or y over x.
[tex] \frac{3}{1} - \frac{5}{5} [/tex]
You will get the same answer nomatter which order these are values are in. Now, solve for this equation.
[tex] \frac{ - 2}{ - 4} [/tex]
Now this is negative and kind of messy, although, we can turn both values into positive values without the answer changing, just be careful on other problems with this technique as it doesn't always work.
[tex] \frac{2}{4} [/tex]
Now we can simplify again.
[tex]\frac{1}{2}[/tex]
The slope is 1/2!

6x-3-11-8x=2 please show work
Answer: is x = -8
this is how i got it ______
6 x - 3 - 11 - 8 x = 2
(simplify both sides and combine like terms)
(6x + -8x ) + ( -3 + -11) = 2
- 2x + -14 = 2
-2x - 14 = 2
( then you add 14 to both sides)
- 2x - 14 = 2
+14 +14
-2x = 16
( then you divide both sides by -2)
-2x / -2 = 16/ -2
x = -8
ta da!! happy to help!
it made it here. this is for the second one.
( first, we subtract 8n from both sides)
13n + 26 = 8n - 29
-8n -8n
5n + 26 = -29
( then we subtract 26 from both sides)
5n + 26 = -29
- 26 -26
5n = - 55
(after that we divide both sides by 5, we do this to make n alone )
5n/ 5 = -55/ 5
n = -11

A grocery store sells oranges by the crate. An empty crate weighs 1,000 grams. Each orange weighs at least 300
grams. Which inequality best describes the total weight in grams, w, of the crate of oranges in terms of, g, the
number of oranges in the crate?
A) w 300g + 1,000
B) w 2 300g - 1,000
C) w S 300g - 1,000
D) W S 300g + 1,000
Answer:
A.
[tex] w \ge 300g + 1000 [/tex]
Step-by-step explanation:
weight of empty crate = 1000 grams
weight of an orange = at least 300 grams
That means that the weight of an orange is equal to or greater than 300 grams.
Weight of g oranges = at least 300g
Total weight of crate and oranges = w

Hi there!
[tex]\large\boxed{g(f(x)) = 108x^{2} - 156x + 46}[/tex]
f(x) = 6x - 4
g(x) = 3x² - 2x - 10
To find (g(f(x)), substitute in the equation of f(x) as 'x' in g(x):
g(f(x)) = 3(6x - 4)² - 2(6x - 4) - 10
Simplify:
= 3(36x² - 48x + 16) - 2(6x - 4) - 10
= 108x² - 144x + 48 - 12x + 8 - 10

Lee drew five rectangles as shown on this coordinate grid
Given:
Lee drew five rectangles as shown on this coordinate grid .
To find:
The correct statement.
Solution:
From the given diagram, it is clear that,
Dimensions of rectangle x are 6 by 3 units.
Dimensions of rectangle A are 7 by 3 units.
Dimensions of rectangle B are 6 by 3 units.
Dimensions of rectangle C are 3 by 6 units.
Dimensions of rectangle D are 6 by 4 units.
Dimensions of rectangle x and B are same and clearly it can be translation or rotation about the origin.
Dimensions of rectangle x and C are same but only rotation is not sufficient to get rectangle C from rectangle x.
Dimension of rectangle x, A and D are different, so they are not congruent and we cannot get rectangle A and D by rotation, reflection and translation.
Therefore, the correct option is B.
Calculate the slope of a line that passes through the points (6, -12) and (15, -3).
A.0
B.1
C.53
D.9
Answer:
B. 1
Step-by-step explanation:
The slope is calculated by taking the difference in the y-coordinates of two points and dividing that by the difference in the x-coordinates of those two points.
Here, we have (6, -12) and (15, -3).
The difference in the y-coordinates is:
15 - 6 = 9
The difference in the x-coordinates is:
-3 - (-12) = -3 + 12 = 9
Divide 9 by 9:
9/9 = 1
The slope is thus 1, and the answer is B.

Answer:
y = -1Step-by-step explanation:
First let us get the slope of the line PQ and RS
For PQ;
Given P(6, -2) and Q(-2,8)
slope m = 8-(-2)/-2-6
slope of pQ = 10/-8
slope of PQ = -5/4
For RS
R ( − 4 , 3 ) and S(-9, y)
slope of RS = y-3/-9+4
slope of RS = y-3/-5
For PQ to be perpendicular to RS, the product of their slope must be -1
Hence -5/4 (y-3/-5) = -1
y-3/4 = -1
cross multiply
y-3 = -4
y = -4+3
y = -1
Hence the value of y for PQ to be perpendicular to RS is -1

Please answer the following essay question:
One recipe uses 1 3/4 cups of milk. Another recipe uses 1 1/2 cups of milk. You have 3 cups of milk at home. Do you have enough milk to make both recipes? Explain.
Answer in paragraph form using complete sentences and include any calculations, graphs, and labeled diagrams as appropriate.
Answer:
No, 3 1/4 is more
Step-by-step explanation:
1 3/4 added by 1 1/2 equals 3.25
Think of it as quarters.
you have $1 and 75 cents and in the other one you have $1 and 50 cents
together you would have $3 and 25 cents.
Okay now the paragraph form...
You would not have enough milk because three and one-fourth (cups of milk) is more than three (cups of milk). I found my answer by adding one and three-fourths by one and a half. You would have to go buy one-fourth of milk if you wanted to create both recipes.

An art museum opens at 9 a.M. And closes at 5 p.M. The function V gives the number of visitors in a museum h hours after it opens. Explain what this statement tells us about the situation: V(1.25)=28
Answer:
What the equation is telling us is that after opening for 1 hour 15 minutes, there were 28 visitors
Step-by-step explanation:
The function we are given is ;
V(1.25) = 28
what this mean is that the number of visitors in the museum after 1.25 hours of opening is 28
1.25 hours is same as 1 hour (0.25 * 60) minutes
What is in the bracket is trying to convert the 0.25 hours to minutes
Since 1 hour is 60 minutes, 0.25 will be (0.25 * 70)
Which is 1 hour 15 minutes
So after opening for 1 hour 15 minutes, the museum had 28 visitors
A statement is convert into the equation by keeping the conditions equal in the form of expressions.
The given function tells that, in 1 hour, 15 minutes of the number of visitors, visit the museum is 28.
To identify the statement in the form of equation we need to know about the equation of statement.
How to make equation using statement?A statement is convert into the equation by keeping the conditions equal in the form of expressions.
Given information-
The art museum opens at 9 A.M.
The art museum closes at 5 P.M.
The function [tex]V[/tex] gives the number of visitors in a museum [tex]h[/tex] hours after it opens.
The statement in the form of equation given in the problem is,

Here bracket value (1.25) of function [tex]V[/tex] tells the number of hours in which 28 visitors visit the museum.
Convert 1.25 hours is the 1 hour and 0.25 hours.
AS one hour equal to 60 minutes thus, the number of minutes in 0.25 hours,
[tex]=0.25\times60\\=15[/tex]
Hence the given function tells that, in 1 hour, 15 minutes of the number of visitors, visit the museum is 28.

Given:
An elephant drinks 49 gallons of water per day.
A rhinoceros drinks 21 gallons of water per day.
To find:
The total amount of water the animals will drink in 8 days.
Solution:
In each day,
Elephant drinks = 49 gallons
Rhinoceros drinks = 21 gallons
Total amount of water they will drink each day is
[tex]49+21=70[/tex]
They will drink 70 gallons in each days.

At a zoo, 3 pandas eat a total of 181 1 2pounds of bamboo shoots each day. The male panda eats 3 times as much as the baby. The female eats twice as much as the baby. How many pounds of bamboo shoots does the female panda eat?
Answer:
6037.2 pounds of bamboo shoots does the female panda eat.
Step-by-step explanation:
Total pandas = 3
Total bamboo shoots eaten = 18112 pounds
Let baby panda eats bamboo = x
Male panda eats bamboo= 3x
Female panda eats bamboo = 2x
So, the equation will become
[tex]x+3x+2x=18112[/tex]
Now solving the equation to find value of x
[tex]x+3x+2x=18112\\6x=18112\\x=\frac{18112}{6}\\x=3018.6[/tex]
The value of x we get : x=3018.6
So, baby panda eats bamboo shoots = 3018.6 pounds
Male panda eats bamboo shoots = 3x = 3(3018.6) = 9055.8 pounds
Female panda eats bamboo shoots = 2x = 2(3018.6)= 6037.2 pounds
So, 6037.2 pounds of bamboo shoots does the female panda eat.
The flower shop recieved a shipment of 342 pink roses and 330 red roses. The shop owner uses 8 roses to make one arrangement. How many arrangements how many arrangements can the shop owner make if he uses all the roses
Answer:
84 arrangements
Step-by-step explanation:
First, we need to calculate the total number of roses that the shop owner has. We do this by adding the pink roses and the red roses that the owner has.
342 + 330 = 672 total roses
Now that we have the total number of roses we simply divide by the number of roses needed for each arrangement (8) in order to calculate the total number of arrangements that the owner can make.
672 / 8 = 84 arrangements
