Answer:

h(x) increases by 15 units.

Step-by-step explanation:

Given that

h(x)=\frac{-5x}{7}-3\\ \\

This is nothing but a straight line with slope equal = -5/7

Hence rate of change of y with respect to x =-5/7

Or for a unit increase in we have 5/7 decrease in h(x)

Using the above we find that when x decreases by 21

we have h(x) to increase by 21(5/7)

=15

So y increases by 15 units

antiseptic1488 [7]

Answer:

9 boards

Step-by-step explanation:

2/3 of the porch= 6 boards

so to figure out how much one third of the porch needs you find half of what it takes to fill in 2/3 of the porch and you get 3.

so 3=1/3 of the porch

then you simply do 3times 3 or 3+3+3 and you get 9

so it takes 9 boards to fill the whole porch
