Answer:
Step-by-step explanation:
carnival A : $ 6 dollar admission and $ 1.50 per ride
A(x) = 1.5x + 6
carnival B : $ 2.50 admission and $ 2 per ride
B(x) = 2x + 2.5
how many rides can Marnie go on so that the total cost of attending both is the same...
1.5x + 6 = 2x + 2.5
6 - 2.5 = 2x - 1.5x
3.5 = 0.5x
3.5 / 0.5 = x
7 = x <=== she would have to go on 7 rides for them to both cost the same
Your equation will be y = 3.
The y-intercept is three and there is no slope.
Hope this helps!
Answer:
171/12500
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
<u>Given function</u>
<u>We can find its factors:</u>
- x³ + 3x² - 7x - 21 =
- x²(x + 3) - 7(x + 3) =
- (x² - 7)(x + 3)
We can conclude that the given polynomial function is fully divisible by (x + 3) and the quotient is (x² - 7)
Also one of zeros of the function is -3
