Suppose two lines are parallel.

<h3>3 Answers: Choice A, Choice B, Choice E</h3>

============================================================

Explanation:

Let's go through each answer choice one by one to see if it's true or false.

  • A) This is true. Parallel lines have equal slopes, but different y intercepts.
  • B) This is true because of the corresponding angles theorem.
  • C) This is false. The statement applies to perpendicular lines, rather than parallel ones.
  • D) This is false in general. The only time it's true is when the consecutive interior angles are 90 degrees each. Otherwise, the statement is false.
  • E) This is true. Let's say we drew any diagonal line we wanted. Now imagine picking a point on that line and shifting it up 5 units. Do this for another point and draw a line through the two separated points. This forms a parallel line. The upper line has been shifted up 5 units compared to the lower line.
  • F) This is false in general. It's only true when both alternate interior angles are 90 degrees each; otherwise, it is false.

one of the solutions to x2 − 2x − 15 = 0 is x = −3. what is the other solution? x = −5 x = −1 x = 1 x = 5
Goryan [66]
x^{2} -2x-15=0
P(-15)
s(-2)
x^{2} -5x+3x-15
=x(x-5)+3(x-5)
=(x+3)(x-5)
x=5
