<h3>Answer:  -19, -15, -9, -1, 9   (choice A)</h3>

===================================================

Explanation:

If we plug in x = -2, then we get,

y = x^2 + 7x - 9

y = (-2)^2 + 7(-2) - 9

y = 4 - 14 - 9

y = -10 - 9

y = -19

So x = -2 leads to y = -19. The answer is between A and D.

---------

If you repeat those steps for x = -1, then you should get y = -15

Then x = 0 leads to y = -9

x = 1 leads to y = -1

Finally, x = 2 leads to y = 9

The outputs we get are: -19, -15, -9, -1, 9 which is choice A

Choice D is fairly close, but we won't have a second copy of -15, and  we don't have an output of -19.

Rewrite the equation C = 3.59q + 54,293 as a function of q.
MAVERICK [17]

The equation, when rewritten would be written as:    

q = ( c - 54293 ) / 3.59

<h3>How to rewrite the equation in order to make q the subject</h3>

C = 3.59q + 54,293

We have the equation above, what we would have to do now would be to write the equation in such a way that q would be the subject of the formula.

This would be

3.59q = C -  54,293

Next we have to divide through by the value of q

q = \frac{C - 54293 }{3.59}
