Answer:
A
Step-by-step explanation:
To find an inverse function you switch f(x) and x, and solve for f(x) (in this case you also rename it to g(x) )
inverse of y=(x-4)/5 is
5x = x -4
x = 5x + 4 so A works
Answer:
0.25t²
Step-by-step explanation:
(0.5t)² = 0.5² × t² = 0.25t²
Factorize
(x- 8 )(x+ 4)
answers are
x-8=0 x=8
x+4=0 x=-4
Step-by-step explanation:
m-(-3)>17
m +3>17
m >17-3
m>14
Answer:
15 ft
Step-by-step explanation:
We can use the properties of similar triangles.
16/8 = 30/x
2 = 30/x Multiply each side by x
2x = 30 Divide each side by 2
x = 15 ft
The shadow is 15 ft long.
Check:
16/8 = 30/15
2 = 2
