Preeeeetty sure it's just 16 for that.
Are you sure you submitted the whole problem?
Answer:
n = -5, 3.
Step-by-step explanation:
n^2 + 2n - 15 = 0
Let's check if we can factor this quadratic:
We need 2 numbers whose product is -15 and whose sum is +2.
There are 2 such numbers and they are +5 and -3, so the factors are:
(n + 5)(n - 3) = 0.
n + 5 = 0 or n - 3 = 0
therefore the zeroes are -5 and 3.
Answer:
y=16x+36
Step-by-step explanation:
cleaning services start at $36 for one hour and add $16 to total price per hour.
16(1)+36=52
16(2)+36=68
16(3)+36=84
16(4)+36=100
