Answer:

The answer to your question is There is only one solution (0, -2)

Step-by-step explanation:

Data

Equation 1 x - y = 2

Equation 2 x + y = -2

Solve for y

Equation 1 y = x -2

y = x - 2

Equation 2 y = - x - 2

See the graph below

These lines cross in point (0 ,-2), that is the only solution.

If the lines have not crossed, they were parallel lines.

Maria estimates college tuition and fees, room and board, books, and other charges total $10,100. She will receive a scholarship

garri49 [273]

Maria needs to save $187.50 per month in order to attend college.

First, subtract the $1,100 scholarship from the cost of college, or $10,100, to get $9,000. This is the amount that she needs to save after 4 years. Next, since she is saving monthly, we need to know how many monthly periods are in 4 years, so multiply 12 months/year by 4 years to get 48 monthly periods. Finally, divide the total amount needed ($9,000) by the monthly periods (48) to get $187.50. This answer would change if she earned any interest on her savings, and depending on the compounding period, if any, for such interest.
