AC has endpoints
A(3,7) and C(6,11).
Find AB if B is the
midpoint of AC.
Answer:
d=2.5
Step-by-step explanation:
first find the coordinate of B(mid point of AC):A(3,7) C(6,11)
d=√(6-3)²+(11-7)²
d=√3²+4²
d=√9+16=√25=5
since B is the mid point : d/2=5/2=2.5
Another way :B(x1+x2/2 , y1+y2/2) , x1=3 , x2=6, y1=7, y2=11
B(9/2,18/2)
B(9/2,9)
Find AB : the length or distance between 2 points:
d=√(x2-x1)²+(y2-y1)²
d=√(3-9/2)²+(7-9)²
d=√(-3/2)²+(-2)²
d=√1.5²+4
d=√6.25
d=2.5
the letters of the word combine are placed at random in a row in how many ways can an arrangement occur such that all vowels are placed together
==========================================================
Explanation:
The word "combine" has three vowels o, i, and e.
One grouping of the three vowels together leads to oie, which we'll replace with Z for now.
So we have the "word" Zcmbn after taking out the vowels and replacing with Z temporarily. There are 5 letters in Zcmbn making 5! = 5*4*3*2*1 = 120 different permutations.
Within any permutation of Zcmbn, there are 3! = 3*2*1 = 6 ways to arrange the sequence oie
So overall there are 6*120 = 720 different ways to arrange the word "combine" such that all the vowels stick together.

Answer:
[tex]y=8x-25[/tex]
Step-by-step explanation:
Given the coordinates:
(3,−1) and (4,7)
To find:
The equation of line passing through the given points.
Solution:
Let us have a look at the slope intercept form of a line:
[tex]y=mx+c[/tex]
c is the y intercept.
Where [tex]m[/tex] is the slope of the line passing through the points [tex](x_1,y_1),(x_2,y_2)[/tex]
Formula for slope is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]x_1 = 3\\y_1 = -1\\x_2 = 4\\y_2 = 7[/tex]
[tex]m=\dfrac{7-(-1)}{4-3}\\\Rightarrow m = 8[/tex]
So, equation of line becomes:
[tex]y=8x+c[/tex]
Let us put (4, 7) to find the value of c:
[tex]7=8\times 4 +c\\\Rightarrow c = -25[/tex]
So, the equation is:
[tex]y=8x-25[/tex]
The equation of the line passing through the points (3.-1), and (4,7) is [tex]y=8x-25[/tex].
Given information:
The given line passes through the points (3.-1), and (4,7).
It is required to write the equation of the line.
Use the two-point form of a line to write the equation of the line:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\\y-(-1)=\dfrac{7-(-1)}{4-3}(x-3)\\y+1=8(x-3)\\y+1=8x-24\\y=8x-25[/tex]
From the above equation of the line, the slope is equal to 8.
Therefore, the equation of the line passing through the points (3.-1), and (4,7) is [tex]y=8x-25[/tex].

If the tangent line to y = f(x) at (5, 2) passes through the point (0, 1), find f(5) and f '(5).
Answer:
f(5) = 2
f'(5) = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Tangent line to a function y = f(x) on a point (5, 2) passes through two points (5, 2) and (0, 1)
Let the equation of the line is,
y - y' = m(x - x')
Slope of a line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{2-1}{5-0}[/tex]
= [tex]\frac{1}{5}[/tex]
Therefore, equation of the line passing through (0, 1) and slope = [tex]\frac{1}{5}[/tex] will be,
y - 1 = [tex]\frac{1}{5}(x-0)[/tex]
y = [tex]\frac{x}{5}+1[/tex]
Function representing equation will be,
f(x) = [tex]\frac{x}{5}+1[/tex]
At x = 5,
f(5) = [tex]\frac{5}{5}+1[/tex]
= 1 + 1
= 2
f(5) = 2
f'(x) = [tex]\frac{d}{dx}(\frac{x}{5}+1)[/tex]
= [tex]\frac{1}{5}[/tex]
Therefore, f'(5) = [tex]\frac{1}{5}[/tex] will be the answer.

The per capita (per person) income from 1980 to 2010 can be modeled by
f(x) = 2000(X – 1980) + 10,000
where x is the year. Determine the year when the per capita income was $18,000.
The per capita income was $18,000 in the year N.
Answer:
X= 1984
Step-by-step explanation:
f(x) = 2000(X – 1980) + 10,000
Where,
f(x)= per capita income
x= year
Find x when f(x)= $18,000
f(x) = 2000(X – 1980) + 10,000
18,000 = 2000(X - 1980) + 10,000
18,000 = 2000X - 3,960,000 + 10,000
18,000 = 2000X - 3,950,000
Add 3,950,000 to both sides
18,000 + 3,950,000 = 2000X
3,968,000 = 2000X
Divide both sides by 2000
X= 3,968,000 / 2000
= 1984
X= 1984
Therefore, the per capita income was $18,000 in the year 1984

Solve the equation for x.
answer:
x=-2
Step-by-step explanation:
my suggestion for this problem and all problems like it would to turn everything into 6ths. 1/3 would become 2/6. and 2 would become 12/6. leave the negatives. now you'll add 2/6 to -12/6. which will equal 10/6. divide 10/6 by 5/6 and youll get -2. x=-2
Answer:
x = -2
Step-by-step explanation:
● (5/6)x - (1/3) = -2
Add (1/3) to both sides
● (5/6)x - (1/3) + (1/3) = -2 + (1/3)
-2 is (-6/3)
● (5/6)x = (-6/3) + (1/3)
● (5/6)x = -5/3
Move 5/6 to the other side and switch the places of 5 and 6
● x = (-5/3) × (6/5)
● x = -30/15
● x = -2

18. A shelf holds fewer than 50 cans. If all of the
cans on this shelf were put into stacks of
five cans each, no cans would remain. If the
same cans were put into stacks of three cans
each, one can would remain. What is the
greatest number of cans that could be on
the shelf?
Answer:
40
Step-by-step explanation:
Given that the number of cans are fewer than 50.
Let the number of cans = [tex]x[/tex]
It is given that no cans remain if they are put in the stacks of five cans each.
i.e. number of cans are a multiple of 5.
Let us have a look at the numbers in decreasing order which are multiples of 5 and are lesser than 50.
45, 40, 35, 30, ......
Now, let us check the numbers one by one.
If [tex]x=[/tex] 45,
Now, they are placed on stacks of three each and one can remains.
So, the remainder when [tex]x[/tex] is divided by 3 will be 1.
But when 45 is divided by 3, remainder is 0.
Now, let us check next greatest number, which is 40.
When 40 is divided by 3, the remainder is 1.
Therefore, greater number of cans can be 40.
Solve for y. I REALLY NEED HELP ON THIS!! 2(3y+6x)=2(5y-2x)
Answer:
y = 4x
Step-by-step explanation:
2(3y + 6x) = 2(5y - 2x)
Divide both sides by 2.
3y + 6x = 5y - 2x
Subtract 5y from both sides. Add 2x to both sides.
-2y = -8x
Divide both sides by -2.
y = 4x

{(-1, 4), (0, 4), (1, 2), (5, 3), (7, 1)}
Given:
Different functions in the ordered pairs.
To find:
The function which has an inverse that is also a function.
Solution:
A relation is a function, if there exist unique output for each input.
The inverse of a function is a function, if there exist unique input for each output in the function.
It means, the inverse of a function is a function if each y value has unique x-value.
In {(-1, -2), (0, 4), (1, 3), (5, 14), (7,4)},
For y=4 we have x=0 and x=7, therefore, the inverse of this function is not a function.
In {(-1, 2), (0, 4), (1, 5), (5, 4), (7, 2)} ,
For y=4 we have x=0 and x=5, therefore, the inverse of this function is not a function.
In {(-1, 3), (0, 4), (1, 14), (5, 6), (7, 2)} ,
For all y value we have unique x values, therefore, the inverse of this function is a function.
In {(-1, 4), (0, 4), (1, 2), (5, 3), (7, 1)},
For y=4 we have x=-1 and x=0, therefore, the inverse of this function is not a function.
Therefore, the correct option is C.

x ∈ ( - 9 : + oo)
Step-by-step explanation:[tex]-\frac{1}{3}(5x+3)<14\\ \\-(5x+3)<42\\\\-5x-3<42\\\\-3-42<5x\\\\-45<5x\\\\5x>-45\\\\x>-9\\\\[/tex]
x∈ ( - 9 ; + oo)
Answer:
x > -9
Step-by-step explanation:
you want to multiply both sides of the inequality by 3/1 to make
-1/1 (5x+3) < 42/1
any expression divided by 1 remains the same
-1 (5x+3) < 42/1 ⇒ - (5x+3) < 42/1 ⇒ - (5x+3) < 42
Where there is a - in front of an expression in parentheses, change the sign of each term in the expression
-5x -3 <42
Then move the constant to the right-hand side and change its sign
-5 < 42 + 3
Add the numbers and you'll get
-5x < 45
Divide both sides of the inequality by -5 and flip the inequality sign and your answer would be
x > -9

If you sell ice cream cones at the football game you must sell 25 to make a profit. You have already sold 15 cones. Write an inequality that can be solved to show all the numbers of cones, c, that you will still need to sell
Answer:
The inequality to describe the problem is 15 +c >25.
We must sell more than 5 cones to make a profit
Step-by-step explanation:
From this problem, we can see that we need to sell a number of cones (c), that when added to the 15 cones that we have already sold, the result will be greater than 25.
To set up the inequality sign, we need to, first of all, know the inequality sign that we will be using. From the preceding statement, we can see that we need to sell greater than a certain number of cones.
This should tell us that we will be needing the greater-than sign (>).
The next step is to know the format the equation should take:
We have sold 15 cones; We need to sell c more to make it greater than 25.
This will be 15 +c >25.
The inequality to describe the problem is 15 +c >25.
from this, we can see that c > 5 cones.
We must sell more than 5 cones to make a profit
6x + 2 = 9x - 4 help me please
Answer:
x=2
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
6x + 2 = 9x - 4
We want terms with x on the left side and numbers on the right side.
Subtract 9x from both sides.
6x - 9x + 2 = 9x - 9x - 4
-3x + 2 = -4
Subtract 2 from both sides.
-3x + 2 - 2 = -4 - 2
-3x = -6
Divide both sides by -3.
-3x/(-3) = -6/(-3)
x = 2
What is 5+x+11x=11x+11
Answer:
x = 6
Step-by-step explanation:
Solve for x:
11 x + x + 5 = 11 x + 11
Hint: | Add like terms in 11 x + x + 5.
x + 11 x = 12 x:
12 x + 5 = 11 x + 11
Hint: | Move terms with x to the left hand side.
Subtract 11 x from both sides:
(12 x - 11 x) + 5 = (11 x - 11 x) + 11
Hint: | Combine like terms in 12 x - 11 x.
12 x - 11 x = x:
x + 5 = (11 x - 11 x) + 11
Hint: | Look for the difference of two identical terms.
11 x - 11 x = 0:
x + 5 = 11
Hint: | Isolate terms with x to the left hand side.
Subtract 5 from both sides:
x + (5 - 5) = 11 - 5
Hint: | Look for the difference of two identical terms.
5 - 5 = 0:
x = 11 - 5
Hint: | Evaluate 11 - 5.
11 - 5 = 6:
Answer: x = 6
Answer:
x = 6
Step-by-step explanation:
5 + x + 11x = 11x + 11
5 + 12x = 11x + 11
5 + 1x = 11
1x = 6
x = 6
