Answer:
(1,-4)
Step-by-step explanation:
First manipulate the second equation so that y is by itself
x-y=5
-y=-x+5
y=x-5
then substitute that y in for the y in the above equation and solve for y
y=-2x-2
x-5=-2x-2
3x-5=-2
3x=3
x=1
Now that you have the x-coordinate, find the y-coordinate by plugging in the x-value in either of the equations
y=-2x-2
y=-2(1)-2
y=-2-2
y=-4
I see that you're using deltamath, and I think for the graph questions, you could first place a point for the y-intercept of one of the equations, and then place another point that is on the graph of the equation. Once you plotted both lines, just see the point where they meet and that is where the two systems of equations meet.

Answer:The answer is D
Step-by-step explanation:
<h3>Answer: 12</h3>
Explanation:
When you divide by 5, the possible remainders are one of these numbers {0,1,2,3,4}. So it's the set of whole numbers from 0 to one less than 5.
This means the largest value of A is A = 4.
Similarly, the largest value of B is B = 8 because the possible remainders when dividing by 9 are {0,1,2,3,4,5,6,7,8}.
Therefore, the largest possible value of A+B is 4+8 = 12.
Given the point (2,-2) and the slope m = -1/2, we can find the equation of the line using the point-slope formula:
therefore, the equation of the line is y = -1/2x -1
