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:
-23
Step-by-step explanation:
You combine the numbers
8+(-13)-18=
add 8 to -13
-5
add -18 to -5
-23
Add the numerators and keep the denominator:
I say around 210-220 is a good answer
Answer:
A. 25%
Step-by-step explanation:
If you multiply something by 0.75, you're multiplying it by 75%, and that means you're losing 25% each time, so the rate of decay is 25%
