and mixed number form its -2 3/17
Answer:
C
Step-by-step explanation:
You know two lines y=ax+b and y=mx+n that are perpendicular, so we have the product a*m=-1
+ This line is perpendicular to y=13x-5, so it has equation: y=-1/13x+b
+ And it passes through the point (3;1), so we have x=3, y=1. So 1=-1/13 *3+b
and b= 1+3/13= 16/13
And we have y=-1/13x+16/13
Have fun

Step-by-step explanation:
(x-9)(x+2)=x^2______-18
x^2+2x-9x-18=x^2____-18
x^2-7x-18=x^2____-18
That's what I got don't quote me on it though. Sorry if I couldn't help much
