Answer:

Part A) $202.50=9

Part B) $292.50=11

Step-by-step explanation:

Part A) y is the total cost, x is the total number of students. Therefore, y=x.

Which makes $202.50=9

Part B) since $202.50= 9 students,

1 student= $202.50÷9 = $22.50

Since 4 students joined,

4 students= $22.5 × 4= $90.00

4+9= 11 students

So 11 students= $202.50+$90.00 =$292.50

the total cost will now be $292.50

Answers

Answer:

0= 30

Step-by-step explanation:

-7(3x+5) +20=5)3-5x)+4x

-21x-35+20=5)3-5x)+4x

Add the numbers

-21x-35+20=5)3-5x)+4x

-21x-15=5)3-5x)+4x

Rearrange terms

-21x-15=5)3-5x)+4x

-21x-15=5(-5x+3)+4x

Distribute

-21x-15=-25x+15+4x

Combine like terms

-21x-15=-21x+15

Add 15 to both sides of the equation

-21x-15+15=-21x+15+15

Simplify

Add the numbers

-21x=-21x+30

add 21 to both sides of the equation

-21x+21x= 21x+30+21x

Simplify

combine like terms

Which of the following is the minimum value of the function y= 1/2x^2 + 2x + 8?

A. 8

B. 0

C. 4

D. 6

Answers

Start by using -b/2a to find the x value of the vertex (which is where the minimum value would be).
-2/1 = -2 = x value of the vertex
Plug in the x value of the vertex to get the minimum value
1/2(-2)^2 + 2(-2) + 8
2 - 4 + 8
6 = y value of the vertex, which is also the minimum.
Therefore, the minimum value of the function is D. 6
