Review for Math 1: Outcomes 1 - 4

Friendship’s soccer team purchased uniforms and equipment for a total cost of $912. The equipment cost $612, and the uniforms cost $25 each.

Which equation could be solved to determine the number of uniforms, x, the school purchased?

• $612x\ +\ 25\ =\ 912$

• $912\ =\ 612\ +\ 25x$

• $912\ =\ 612x\ +\ 25x$

• $612\ -\ 25x\ =\ 912$

Does the mapping diagram represent a function?

• Yes, it is a function.

• No, it is not a function.

Is the graph a function?

• Yes, it is a function.

• No, it is not a function.

Which set of ordered pairs is NOT a function?

• {(-2, 5), (9, 4), (-5, 6), (0, 4)}

• {(-3, 4), (6, 4), (8, 4), (0, 4)}

• {(0, 2), (-9, 7), (-5, 1), (3, 10)}

• {(-3, 4), (-7, 2), (-3, 8), (0, 7)}

For which interval is the function increasing?

• $x\ >\ 1$

• $x\ \ge1$
  

• $x\ >\ 2$

• $x\ \ge\ 2$

What is the range of the relation shown?

• $-2\le y\le14$

• $-2\le x\le2$
  

• {-2, -1, 0, 1, 2}

• {-2, 2, 6, 10, 14}

What is the equation of the line shown on the graph?

• $y\ =\ 3x\ -\ 2$

• $y\ =\ -2x\ +\ 3$

• $y\ =\ -\frac{1}{2}x\ +\ 3$

• $y\ =\ \frac{1}{2}x\ +\ 3$

Solve for x.

 $\frac{x\ -\ 4}{-6}=\ 3$  

• x = -22

• x = -14

• x = 14

• x = 26
