PLEASE HELP ME! THIS ASSIGNMENT WAS DUE YESTERDAY!!

Mathematics
1 answer:
djyliett [7]3 years ago
4 0

Answer:

700$ at 2% 800$ at 4%

Step-by-step explanation:

x+y=1500 This is because the total is 1500 dollars into 2 different accounts, x and y.

0.02x+0.04y=44 This is because it says 2 percent interest in one account and 4 percent in the other, and the totals add up to 44 dollars.

Now use elimination method.

x+y=1500(-0.02)=-0.02x+-0.02y=-30

0.02x+0.04y=44

Now you end up with 0.02y=14, solve for y and you get 700. That's the value of y which now you can then subtract from 1500 and get 800 which is the value of x.

What is an equivalent function to f(x)=(x-2)^3
atroni [7]

Answer:

x^3-6x^2-4x-8

Step-by-step explanation:

First you would multiply (x-2) by itself (x-2) to get

x^2-2x-2x+4

then you would combine like terms

x^2-4x+4

Then you would multiply that by x-2

(x^2-4x+4)(x-2)

x^3-2x^2-4x^2-8x+4x-8

then you combine like terms

x^3-6x^2-4x-8

Not quite understand the question. We assume that the issue of ratios of numbers of 800 and 8000.

Conversely, 8000 it ten times at 800 and 1000% of 800.
