F(x) = x^2 - 3x - 18
Find the values that when multiplied equal -18 and when added equal -3 (6 and -3)
Plug it into f(x) = (x - 1st value)(x - 2nd value)
f(x) = (x - 6)(x + 3)
0 = (x - 6) (x + 3)
(One of the factors has to equal zero, so set them both equal to zero)
x - 6 = 0
x = 6
x + 3 = 0
x = -3
x = 6, x = -3
Answer:
y = m x + b is the standard form of a straight line
m = (y2 - y1) / (x2 - x1) = (10 - (-8)) / (-3 - 0) = 18 / -3 = -6
When x = 0 y = b from the equation for a line
y = - 8
So our equation is
y = -6 x - 8
As a check let x = -2 then
y = (-6 * -2) - 8 = 12 - 8 = 4
Check on the graph to verify that this equation holds

Answer: Choice A) 4</h3>
Explanation:
The rule is that if log(A) = log(B), then A = B
Using this idea, we can then say,
log(t - 3) = log(17 - 4t)
t - 3 = 17 - 4t
t+4t = 17+3
5t = 20
t = 20/5
t = 4
Answer:
35+28=31
Step-by-step explanation:
The answer is indeed 40 K.
