I find it useful to use a graphing calculator to find the zeros of higher-order polynomials. Once you find one or more rational zeros, you can factor them out to find the reduced polynomial factors (or you can use synthetic division).
1. This factors as (5x+2)(3x-1)(x-8). Roots are {-2/5, 1/3, 8}
2. This factors as (x-9)(x²-5x+2). Roots are {2.5-√4.25, 2.5+√4.25, 9}
3. This factors as (x-6)(5x²+3x+1). Roots are{-0.3-i√0.11, -0.3+i√0.11, 6}
The answer is approximately (D) because the true answer is 10203494.6646. I hope this helped! :D
Answer:
steps below
Step-by-step explanation:
a) f(x) = (x+2)² - 9
b) y = (x-h)² + k , (h,k) is vertex vertex (-2 , -9)
x intercept: (x+2)² - 9 = 0
x+2 = ± 3
<u>x = 1 or x = -5</u>
y intercept: <u>y = -5</u>
c) attached
d) y ≥ -9 [-9,∞)

Answer:
88 cans were sold, the most important variable is how much you started with and how much you ended with
Step-by-step explanation:
88 cans were sold because 98-10=88, and the most important variable is how much you started and ended with because the question asks how much were sold and you can't know that without knowing the start amount and end amount which is the 2 variables I used to get 88 in the equation (98-10)
The Equation is 98-10=88
