Y = -3
x - 5y = 7
I have the answer I don’t know how to show my work

Step-by-step explanation:

To use substitution in this problem, you find the Y which ='s -3. That we have clear. Now, the second equation becomes x - 5(-3) =7. A negative times a negative is a positive, so 15. Now, we have x + 15 = 7. Subtract 15 from 7 to get x = -8. Your coordinates, or your answer, will be (-8, -3)

  (x, y) = (-8, -3)

Step-by-step explanation:

"Show your work" means write down the work you did.

Very likely, you put -3 where y is in the second equation. That is what "substitution" means.

  x -5(-3) = 7

  x +15 = 7 . . . simplify

  x = -8 . . . . . subtract 15 from both sides

The solution to this system is ...

  (x, y) = (-8, -3)

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

12.4, 12.387, 12.26, 12.252, 6.241, 6.2, 6.015, 6.009, 1.411, 1.2, 1.056, 1.007, 0.31,   0.13, 0.5, 0.04
