You first identify what supplementary angles are,angles that add up to 180.
5x+2+8x+9=180
17x+11=180-11
17x=169
x=169divided by 17
x=9.9411
x=10 when rounded into the next value
8x*10=80+989
<u>Answer:</u>
The correct answer option is D. .
<u>Step-by-step explanation:</u>
We are given the following expression and we are to simplify it:
Here the variables and are having negative powers. So to change these powers from negative to positive, we will take their reciprocals to get:
Axis -b/2a=-12/2*3=-2
vertex(-2,-3)
