Answer:
I don't know your options, but it is reasonable.
Step-by-step explanation:
Adding a negative is equivalent to subtracting a positive, so you would get
-218-395
=-613
Answer:
-8
Step-by-step explanation:
y2 - y1 / x2 - x1
-15 - 1 / 1 - (-1)
= -16 / 2
= -8
First change the mixed fraction into a improper fraction
8 5/6= 53
53/6 is your improper fraction
then flip it (reciprocal)
6/53 is your answer
hope this helps
Answer: x=-4, y=-7
Problem:
4x-6y = 26
5x-4y=8
You can use substitution or elimination to solve the problem. I’m going to use elimination.
Multiply by -2 => -8x+12y = -52
Multiply by 3 => 15x- 12y = 24
Add those equations together:
7x=-28
x=-4
Plug that into one of the original equations to get y.
4(-4)-6y=26
-16 - 6y=26
-6y=42
y=-7
Check for the other equation to see if this is true. Which in this case it is. So that’s your answer. x=-4, y=-7
