7x-15=33 solve the equation and you should ger x= 2.57
The answer is D. The easiest way to see this is by using the FOIL method.
First
Outside
Inside
Last. So the first is x2, the outside is -10x, the inside is -7x, and the last is 70. So it would be x2-17x+70
All you do is multiply 15 and 6 you get 90. then divide 90 by 9 and you get 10.
It moves the line on the X axis to a different spot when moved
hope this helps <span />
