The answer is (-x+7)(x - 3) or -x^2 + 4x - 21
9^2 - 2^2 = 9*9 - 2*2= 81-4= 77
Answer:
ummm......yes
Step-by-step explanation:
Answer: x=2.5, and x-1=1.5
Step-by-step explanation:
x + 3 = 3x - 1
(-x)= 3 = 2x - 1
(÷2) = 1.5 = x - 1
(+1)= 2.5 = x
Answer: The function that modes this situation would be: y = 475(1 + .0125)^x.
This is an example of an exponential equation. These equations are always in the form y = ab^x.
The a value is the starting value. The b value is the interest rate. The x value is the number of years.
The only thing to be careful about is the rate. We are adding 1.25% or 0.125. Make sure that you are adding 1 whole to the 1.25% and don't just use 0.125.
