One factor will be zero, hence y will be zero, when x=-3.
The other factor will be zero, hence y will be zero, when x=-5.
The zeros of the function are x ∈ {-5, -3}.

This solution makes use of the "zero product rule," which states a product is zero if and only if one or more factors is zero.
So a hack is we know that 20% times 5 =100% and 40 divided by 2=20 so
50=40%
divide both sides by 2
25=20%
20 times 5=100 so
multiply both sides by 5
125=100%
Answer:
Company B
Step-by-step explanation:
A is $0.15/min
because 76/500
B is $0.12/min
because 54/450
Company B is cheaper so it would be the better deal
Answer:
t/8 + t/7 = 1
Step-by-step explanation:
Given in the question that,
time require for Jose to paint the house = 7 hours
time require for Brandon to paint the house = 8 hours
Suppose t means Full house painted.
<h3>
To solve the question we have to figure out how much each of them can paint in ONE hour.</h3>
7 hours----t
1 hour ---- t/7
8 hours----t
1 hour ---- t/8
<h3>
Equation</h3>
t/8 + t/7 = 1 (in one hour)
(7t + 8t)/8(7) = 1
15t/56 = 1
15t = 56
t = 56/15
t = 3.73 hours
Answer:
3
Step-by-step explanation:
Three times three equals nine. Or you can just go by one times one, two times two, three times three.
