Complete steps 2 and 3 to solve the system of equations.

y = 4x – 5,

y = –3

1. Use substitution to create a one-variable linear equation: –3 = 4x – 5.

2. Solve to determine the value of the unknown variable.

3. Write the solution to the system of equations as an ordered pair.

The solution to the system is (, –3).

If the measure of angle 1 is 110 degrees and the measure of angle 3 is (2 x+10 degree), what is the value of x?

*let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why?

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
