We can calculate the speed to be
.. (36 mi)(0.75 h) = 48 mi/h
or we can just assume that is what it is based on the fact that 48 is the only number in any of the offered answers.

distance = speed * time
.. y = 48 * x . . . . . . . . . . . . . . . . corresponds to selection A

_____
There is no question 17.

_____
15. All sections of the graph are linear. All sections except Q show the function increasing (left to right, which is how we talk about it). Thus selection B is the only sensible one.

2( 4c - 7 ) < 8 ( c - 1) - 6 if possible

Sure! Let's do this in order.
First, we can simplify the left side with the distributive property, getting us
8c-14
Next, we can simplify the right side with the distributive property, getting us
8c-8-6.
That gives us 8c-14<8c-8-6.
We can subtract 8c from both sides, getting us
-14<-8-6
Simplify the right side to get
-14<-14
This inequality has no solution. This is because the variable is gone, and the remaining equation isn't true.
