Answer 2

Answer:

The value of 3/8x-4.5 when x=0.4 is -4.35.

Step-by-step explanation:

We have the following function:

$y = \frac{3x}{8} - 4.5$

What is the value of 3/8x-4.5 when x=0.4?

This is the value of y when x = 0.4. So:

$y = \frac{3x}{8} - 4.5 = \frac{3*0.4}{8} - 4.5 = -4.35$

The value of 3/8x-4.5 when x=0.4 is -4.35.
