I think this is the way that the problem was given
Solve x−(−8)=2, for x=6
If so then plug (x=6)==> -6 -(-8)=2==> - 6 +8 =2, hence 2=2
He would be payed $290, you just have to do a "cross multiplication" (as we call it in french), you just have to do 174×40÷24 and there you go :)
Answer:
X-intercepts: (-3,0) and (5,0)
Y-intercept: (0,-15)
Step-by-step explanation:
x^2 - 2x - 15
(x + 3) (x -5)
x +3 = 0
x = -3. (-3, 0)
x - 5 = 0
x = 5. (5, 0)
