Answer:
see below
Step-by-step explanation:
Let N = how much Nellie spends
Let D = how much Debbie spends
Part A
Nellie spends $122 more than Debbie.
N= D +122
Their total expenses amount to $840.
N+D =840
The two equations are
N= D +122
N+D =840
Part B
We can substitute the first equation which is solved for N into the second equation. Every place we see an N in the second equation, we replace it with D+122
Part C
N= D +122
N+D =840
(D+122) +D = 840
Combine like terms
2D +122 = 840
Subtract 122 from each side
2D+122-122=840-122
2D =718
Divide by 2
2D/2= 718/2
D =359
Debbie spends 359
Answer:
f(x) = 4x³+16x²+4x-24
Step-by-step explanation:
Factors are (x+3)(x+2)(x-1)
(x+3)(x²+2x-x-2)
(x+3)(x²+x-2)
x³+x²-2x+3x²+3x-6
x³+4x²+x-6
This could have been the function but the intetcept is 6 here.
So we'll take a miltiple of this one such that the intercept becomes-24
-24/-6 = 4
That multiple is 4
f(x) = 4(x³+4x²+x-6)
f(x) = 4x³+16x²+4x-24
