So you have many ordered pairs here that look like (x , y)
So you take each one, for example (84,12) and plug it into that equation you have
<span>y=7x</span>
(84 , 12) means (x = 84, y = 12 ) so we plug those in
<span>12=7(84)</span><span>
Does that come out true? if it doe...we have a solution..if not...obviously not :)</span>

Answer:
11/4 Pi
Step-by-step explanation:
because 1.= 70/180. (180.=Pi)
so 495 x 70/180
=11/4 Pi
The -2 would be distributed to the x and the 4 making the equation -2x - 8. So, the answer is C.
If all the angles add up to 90 degrees then you can set the equation 7x-9*2x=90
Simplify
9x-9=90
Plus 9 both sides
9x=99
Divide by 9 on both sides
X=11
