<span>We are looking for the value of x if we know the value of y=0.8 and the equasion is: 4x + 8y = 40. First we separate what we don't know on the left side and what we do know on the right: 4x = 40 - 8y. we know y=0.8 so we put that in the equation and we get: 4x = 40 - 8*0.8. Now we have: 4x = 40 - 6.4=33.6. Finally, we divide the left side and the right side by 4 and we get: x=33.6/4=8.35. So x=8.35.</span>

Answer:

1. Below 2. B. d = 8h

Step-by-step explanation:

The graph is a bit confusing. But basically, substitute x for the numbers they give you.

5x

5 · 1 = 5 = y

5 · 2 = 10 = y

5 · 3 = 15 = y

5 · 4 = 20 = y

7x

7 · 1 = 7 = y

7 · 2 = 14 = y

7 · 3 = 21 = y

7 · 4 = 28 = y
