Answer:
The value of 3/8x-4.5 when x=0.4 is -4.35.
Step-by-step explanation:
We have the following function:
[tex]y = \frac{3x}{8} - 4.5[/tex]
What is the value of 3/8x-4.5 when x=0.4?
This is the value of y when x = 0.4. So:
[tex]y = \frac{3x}{8} - 4.5 = \frac{3*0.4}{8} - 4.5 = -4.35[/tex]
The value of 3/8x-4.5 when x=0.4 is -4.35.
