End of Semester Review

April wants to prove that she can solve the system of equations below using the substitution method.
3x + y = 8
y = 4x - 6

Which equation shows the first step in solving the system of equations using the substitution method?

• 7x + 2y = 2
• -x +2y = 2
• 3x + (4x-6) = 8
• 3(4x-6) +y = 8

Emily makes $10 per hour at her job.  Her paycheck was $370.  If h represented the number of hours Emily worked, which equation below represents Emily's paycheck?

• h =10/370
• 370h = 10
• 370 (10) = h
• 10h = 370

Write the polynomial so the powers of x are in descending order.
 9x² + 5x + 27 + 2x³

• 27 + 5x + 9x² + 2x³
• 9x² + 5x + 2x³ + 27
