Mia measures the length of a leaf with her ruler. Which of the following values is most likely the value she measured with her ruler?

A
0.0048 m

B
0.157 ft

C
4.8 cm

D
48.41 mm

most likely C) 4.8 cm

Step-by-step explanation:

Explanation:

We're told that f(x) = -4. That means we can replace the f(x) in the first equation and solve for x.

f(x) = -5x+1

-4 = -5x+1 replaced f(x) with -4

-5x+1 = -4

-5x = -4-1

-5x = -5

x = -5/(-5)

x = 1

As a way to check, we plug in x = 1 to get...

f(x) = -5x+1

f(1) = -5(1)+1

f(1) = -5+1

f(1) = -4

So the answer is confirmed. If f(x) = -4, then x = 1.
