5x + 7y = -29 y = x + 1

  (x, y) = (-3, -2)

Step-by-step explanation:

Perhaps this is a system of equations you want the solution for.

Since you have an expression for y, substitution is a viable approach.

  5x +7(x+1) = -29 . . . . . . substitute for y

  12x = -36 . . . . . . subtract 7 and simplify

  x = -3 . . . . . . . . . divide by 12

  y = (-3) +1 = -2 . . . use the expression for y

The solution is (x, y) = (-3, -2).

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

ratio is 2 : 9

the answer is three

13.5 : 3
