Solve the system of equations.
y = 4x+1
3x + 2y = 13

• (1, 5)
• (5, 1)
• (0.25, 2)
• ∅

Determine if (4, 1) is a solution for the system of equations.
y = -x + 5
y = 2x - 7

• yes
• no

Give the solution to the system.

• (3,1)
• (1,3)
• (-1,3)
• (1, -3)

Add the following polynomials:
 (5x + 2) + (4x + 5)

• 9x -7
• -9x-11
• 9x+7
• x+7

Subtract the following polynomials:
(a³ - 2a²) - (-4a³ + 4a²)

• -5a⁶ - 5a⁴
• 5a³  - 2a²
• -2a³  - 6a²
• 5a³ - 6a²

Find the product:
5xy(6x - y)

• 11x² - y²
• 30x² + y²
• 30x²y - 5xy²
• 11x²y + 5x²y²

Solve by completing the square:
x² + 6x = 55

• x = -14, 2
• x = 14, -2
• x = -5, 11
• x = 5, -11

Solve
a² + 2a - 24 = 0

• a = -6, 4
• a = 6, -4
• a = 12, -2
• a = 8, -3

Solve using the quadratic formula.
2x² - 9x - 35 = 0

• x = 7/2, x = -6
• x = -5/2, x =5
• x = -3/7, x =6
• x = -5/2, x = 7

Determine the values of a, b, and c for the quadratic equation:

4x² – 8x = 3

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3
