Answer/Step-by-step explanation:
4x - 7 = -2x + 12 (Given)
Add 2x to both sides
4x - 7 + 2x = -2x + 12 + 2x (Addition property of equality)
6x - 7 = 12 (Simplication)
Add 7 to both sides
6x - 7 + 7 = 12 + 7 (Addition property of equality)
6x = 19 (Simplification)
Divide both sides by 6
(Division property of equality)

Answer: x = square root of -x + 3 / 2
Step-by-step explanation:
2x^2 + x - 1 = 2
add 1 to both sides
2x^2 + x = 3
subtract x from both sides
2x^2 = -x + 3
square root both sides
2x = square root of -x + 3
divide by 2
x = square root of -x + 3 / 2

Answer:
C = - 8
Step-by-step explanation:

Given a trapezoid WXYZ. In a trapezoid one pair of opposite sides are parallel .Parallel lines have same slope.Slope of line parallel to x axis is 0.If the line starts at the bottom left and goes towards the top right it has negative slope.
All that is true for Trapezoid WXYZ are:
Line WZ has the same slope as line XY.
Line XW has a lesser slope than line YZ.
Line ZW has the same y-intercept as line WZ.
Line XY has a greater y-intercept
