X^2+x-30 -- find two numbers that add to one and multiply to -30, which would be 6 and -5. so now you have x^2+6x-5x-30. factor out x and 5 to get x(x+6)-5(x+6). so you get (x+6)*(x-5)
Answer:
-157.87
Step-by-step explanation:
1) the rules are:
and

2) according to the rules above:

Line through (a,b) with slope m is
y - b = m(x -a)
Here that's line through (a,b)=(5/3, -7) with slope m=-3/4
y - -7 = (-3/4) (x - 5/3)
Solve for y,
y + 28/4 = (-3/4) x + 5/4
y = (-3/4) x - 23/4
Look at the choices.
Answer: D
The function is discontinuous at x=8 because as x approaches 8 from the left, f(x) approaches -1 but as x approaches 8 from the right, f(x) approaches 1 and -1 and 1 are not equal.
