Answer:

-5x - 8y = -5

Step-by-step explanation:

4x - 4y = - 2

-9x - 4y = - 3

This question does not ask you to solve anything. Nor does it ask you to eleminate one of the letters. So you just do as you are asked.

x: 4x - 9x = -5x

y: -4y - 4y = -8y

The numbers on the right

-2 - 3= - 5

Answer: -5x - 8y = -5

PLEASE HELP

Answer:

$593.26

Step-by-step explanation:

We know that the price of the laptop is $2500 and each year its resale value decreases by 25%. It means that 100 - 25 = 75% of the value is retained every year for the resale.

So, the resale value for 1st year = $\frac{75}{100} *2500 =$ $1875

for 2nd year = $\frac{75}{100} *1875 =$ $1406.25

for 3rd year = $\frac{75}{100} *1406.25 =$ $1054.7

for 4th year = $\frac{75}{100} *1054.7 =$ $791.01

for 5th year = $\frac{75}{100} *791.01 =$ $593.25

Or we can use the following formula to find its resale value after 5 years:

$2500*(0.75)^5 =$ $593.26
