Answer:
2x-14 = -37
Step-by-step explanation:
7x + 4 = -19 + 5x,
Subtract 5x from each side
7x-5x + 4 = -19 + 5x -5x
2x +4 = -19
Subtract 4 from each side
2x +4-4 = -19 -4
2x = -23
We want to find 2x -14
2x = -23
2x-14
-23-14
-37
The <em>correct answer</em> is:
D) Rotated perpendicular lines always remain perpendicular lines.
Explanation:
Perpendicular lines, by definition, meet at a 90° angle.
As long as both lines are rotated the same direction and the same angle, then the angle between the two lines will not change. They will continue to be perpendicular, no matter how many degrees or which direction they are rotated.
