If $y = 4$, then $8 + 7y > 36$

$10 + 6 \cdot 2 = 32$

The graph of the ordered pair (0, 5) is on the y-axis.

$\begin{bmatrix} 4 & 5 \\ 6 & 7 \end{bmatrix} = \begin{bmatrix} 5 & 4 \\ 7 & 6 \end{bmatrix}$

The graph of the ordered pair (8, 2) is on the graph of the equation $y = 4x$

$3(8 - 2)$

(3 \cdot 8) \div (3 \cdot 2)

$3 + 4 (5) 6$

$\frac{(12 + 4)}{8}$

$12 + \frac{4}{8}$

If one of the members of {1, 2, 3, 4, 5} is chosen at random, find the probability that it is a solution to the inequality $3x - 1 < 12$.

If $y = 8x - 7$, find $y$ when $x = 25$.

Evaluate the expression when $(x,y)=(4,8)$

$\sqrt{14x + y}$

Evaluate the expression when $(x,y)=(4,8)$

$2x + xy$
