-6 + 7 = 1 and -6*7 = -42
So f(x) = (x + 7)(x - 6)
(4 2/3) / (4 1/5) = 1.111
F(x)=2(x+10)=24
2(x+10)=24
divide 2
x+10=12
minus 10
x=2
D
simplified original equation: y=-9/5x+13.2
perpendicular slope: 5/9
equation passing through (-6,8): y-(8)=5/9(x-(-6))
y=mx+b form: y = 5/9x + 14
Answer:

Step-by-step explanation:
![=(2x-3)(5x+1)\\\\=2x(5x+1)-3(5x+1)\\\\Distribute\\\\= 10x^2+2x-15x-3\\\\= 10x^2-13x-3\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%3D%282x-3%29%285x%2B1%29%5C%5C%5C%5C%3D2x%285x%2B1%29-3%285x%2B1%29%5C%5C%5C%5CDistribute%5C%5C%5C%5C%3D%2010x%5E2%2B2x-15x-3%5C%5C%5C%5C%3D%2010x%5E2-13x-3%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
