Final Exam Review

Write the y = rule.

• y = 14 + 8x

• y = 14 + 4x

• y = 6 + 8x

• y = 6 + 4x

Write in standard polynomial form.

(3x - 4)(x + 2)

• 3x² - 2x - 8

• 3x² - 2x - 2

• y = 3(1/2)^x

• y = 3 - 1/2x

Factor out the GCF.

8x² - 12x

• 4x(2x² - 3x)

• x(8x - 12)

• 4x(2x - 3)

• 4(2x² - 3x)

Which inequality matches the graph?

• 4x + 3y < 24

• 3x + 4y > 24

• 3x + 4y < 24

Solve.

6x + 3 - 2x - 9 = 18

• x = -6
