The graph will be a shaded region to the right of the solid vertical line x =8
We know that Zoey can tile 1.25 square yards in 20 minutes (which is 1/3 of an hour) so we wanna see how much she can tile in an hour. Multiply 1.25 by 3.
1.25•3= 3.75 or 3 3/4
Simple....
you have: 4(x+7)
To simplify it..distribute..
4(x+7)
4*x=4x
and
4*7=28
Leaving you with...
4x+28
As we can see B is 4x+28
Thus, your answer.
Square (added characters)
