Y=x+3 and y=-x-5.Is the line parallel, perpendicular or neither?

insens350 [35]

Answer:

Perpendicular.

Step-by-step explanation:

For parallel lines slopes are equal.

The slope of y = x + 3 is 1 and the slope of y = -x - 5 is -1 so they are not parallel.

For perpendicular lines m1*m2 = -1 (where m1 and m2 are the slopes).

So these 2 lines are perpendicular.

What is 3x+15-9=2(x+2) ?

Margaret [11]

SOLVING:

3X + 15 - 9 = 2(X + 2)
3X + 6 = 2X + 4
3X - 2X = 4 - 6
X = - 2 ===> The great answer.

TESTING:
$3(-2)+15-9=2(-2+2)\\ \\-6+6=2(0)\\ \\\boxed{0}=\boxed{0}\quad\checkmark\ Correct.$
GOOD LUCK...!!
