8x+15=7
In the statement the phrase the sum of can tell you that it is going to be an addition problem. So 8x ( eight times a number) would be added to the 15, 8x+15. Since its an addition problem the part where it says ' ... is seven', you know that it will all equal 7. So the answer would be 8x+15=7.
Answer: UM

Maddie :
(1,100),(2,80)
slope (rate of change) = (80 - 100) / (2 - 1) = -20/1 = -20
Caitlin :
y = -18x + 120......slope (rate of change) = -18
To determine which rate of change is greater, take the absolute value of the slopes.
Maddy : | -20 | = 20
Caitlin : | -18 | = 18
the greater rate of change is the one with the larger absolute value....so that would be Maddy...function 1 shows a greater rate of change because Maddie spends 20 each month and Caitlin spends 18 each month
Answer: f(x)/g(x) = 3x^2 + 6x - 2 - 12/3x+1
Step-by-step explanation:
The first function is f(x) = 9x^3+21x^2-14
The second function is g(x) = 3x+1
f(x)/g(x = 9x^3+21x^2-14/3x+1
We perform the long division as shown in the attachment to obtain the quotient as: Q(x) = 3x^2+6x - 2 and remainder R = -12
Therefore f(x)/g(x) = 3x^2 + 6x - 2 - 12/3x-1
Where x does not = -1/3
