Answer:a is 52    b is 65

Step-by-step explanation:

a:Write 65% as 65100.

65100 of 80 = 65100 × 80.

Therefore, the answer is 52. If you are using a calculator, simply enter 65÷100×80 which will give you 52 as the answer.

b: it is 65 because it is the same question but in reverse which still gives you the same answer.

Which equation is the inverse of y = 2x^2 - 8?
evablogger [386]

Answer: A

Step-by-step explanation:

y=2x^2-8

1. Swap x and y.

x=2y^2-8

2. Solve for the new y.

Add 8

x+8=2y^2

Divide by 2.

\frac{x+8}{2}=y^2

Extract the square root.

\sqrt{\frac{x+8}{2} }=y
