Match the reasons to the statements in the proof. Given:

m 1 + m 5 = 180°

m 1 + m 4 = 180°

Prove:

1.
m∠1 + m∠5 = 180° and

m∠1 + m∠4=180°

Subtraction property of equality
2.m∠1 + m∠5 = m∠1 + m∠4
Substitution
3.m∠5 = m∠4
If alternate interior angles equal, then lines are ||.
4.is parallel to
Given

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
