It’s -37! | this means the opposite of the number ;)
Answer:
D. 56
Step-by-step explanation:
F(x) = 4x - 9
let f(x) = y, this implies that x = f⁻¹(y)
y = 4x - 9 Let us solve for x.
4x - 9 = y
4x = y + 9
x = (y + 9)/4
Recall that x = f⁻¹(y),
x = (y + 9)/4
f⁻¹(y) = (y + 9)/4
That means that for f⁻¹(x)
f⁻¹(x) = (x + 9)/4
Hope this explains it.
Answer:
6.4 inches
Step-by-step explanation:
We are going to have to use ratio's here. We know that 1 inch = 2.5 feet and we know that Terrance is making a scale model of a car that is 16 feet long. We need to work out the length of the car in inches so,
1 inches = 2.5 feet
? inches = 16 feet
→ We are going to divide 16 by 2.5 and then multiply that answer by 1 to get our result so
16 ÷ 2.5 = 6.4
6.4 × 1 = 6.4
The final answer is 6.4 inches
