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.
5x+(-4)-5x=6x+4-5x
-4=x+4
x=-8
To get rid of 5x on the left side.
Answer:
umm that doesn't make a whole lot of sense if its multiple choice can you give us the options please sorry I couldn't answer
Step-by-step explanation:
Answer:B) 150
Step-by-step explanation:
Area of rec= L×W
= 10×30= 300
Area of shaded area= 1/2 Base× Height
1/2×10×15=75
75×2 = 150
Area of unshaded part= 300-150= 150
The answer is B.
When you set up a ratio of all the corresponding sides, the ratios all equal 2:1
