Here is the ans ...hope it helps:)
Step-by-step Answer:
What is the solution to the system of equations?
y = –3x – 2 ..............(1)
5x + 2y = 15..............(2)
Substitute (1) in (2) to give
5x + 2(-3x-2) = 15
5x-6x-4 = 15
-x-4=15
solve for x:
-4-15 = x
x=-19
Now substitute x=-19 into equation (1)
y = -3x-2 = 57-2 = 55
Therefore the solution is (-19, 55)
Answer:
D
Step-by-step explanation:
Up to 400 pages, the cost is fixed at 5.00 dollars
After 400 pages the cost is 0.01 cents/page
- It's not A. 400 is the number of pages. It is not a cost.
- It's not B either. B means that no matter how many pages you print, it's going to cost 5 dollars + the number of pages times 1 cent.
- C is not the answer. It is really just an answer put it. You pay 1 cent for each page between 400 and what you printed.
- I think D is the answer, but if you get a negative number, then the cost is 5 dollars
