Question 7

The volleyball team at West View High School is comparing T-shirt companies where they can purchase their practice shirts. The graph represents the two companies’ prices. What is the linear equation that represents each T-shirt company?

Revolt · Accepted Answer

D: ✔ y = 7.5x + 30

Question 8

y = 5.5x✔ y = 10.5xy = 6.5x + 30y = 7.5x + 30

Revolt · Accepted Answer

B: ✔ y = 10.5x

Question 9

2(8 – 3x) + 3x = 3✔ 2x + 3(8 – 3x) = 32x + 3y = 8 – 3x

Revolt · Accepted Answer

B: ✔ 2x + 3(8 – 3x) = 3
