Eve earns $14 per hour for yard work and an extra amount for dog walking. Look at the table. Choose the linear function f Eve can use to determine her pay.

• f(x) = x + 14

• f(x) = 12x + 16

• f(x) = 12x + 14

• f(x) = 14x + 12

• y = 3.5x + 12

• y = 3.5x + 10

• y = 4.5x + 11

• y = 4.5x + 9

What is the solution to the system?

• (-1, 3)

• (-3, 1)

• (3, -1)

• (-3, -1)

There are 15 animals in a barn.  These animals are horses and chickens.  There are 44 legs in all.  Which system of equations represents the situation?

• x + y = 15
  4x + 2y = 44

• 4x + 2y = 15
  x + y = 44

• x = 2y + 44
  4x = y + 15

• 2x - 4y = 44
  x - y = 15

Your family goes to a restaurant for dinner. There are 6 people in your family. Some order the chicken dinner for $14.80 and some order the steak dinner for $17. If the total bill was $91, how many people ordered each type of dinner? Write the system of equations in order to solve.

• 2 steak dinners

  4 chicken dinners

• 1 steak dinner

  5 chicken dinners

• 5 steak dinners

  1 chicken dinner

• 4 steak dinners

  2 chicken dinners

Which inequality is shown in the graph?

• y < 2x + 1

Match

• y < x−2 
  y < 3

• y > -x+2
  y > 3

• y < -x+2
  y < 3

• y < -x+2
  y > 3

Simplify:
(3x - 5) ( 4x² - 2x - 3)

• 12x³ - 26x² - 25x + 15

• 12x³ - 20x² - 5x + 15

• 12x³ - 20x² - 6x + 15

• 12x³ - 26x² + x + 15

Classify by number of terms:
3x³ – 6x
