Front

What is the solution to the equation 8v - 4(v + 8) = 8?

Back

10

Front

What is the absolute value of |-26|?

Back

26

Front

Is the relation a function? Why? (x-value 11 has two y-values)

Back

No, because the x-value 11 has two y-values pair with it.

Front

Is this mapping a function or not a function? (Given pairs)

Back

Function

Front

Solve the system by substitution: 5x + 4y = -14, y = -7x - 15

Back

(-2, -1)

Front

What is a function?

Back

A relation where each input (x-value) has exactly one output (y-value).

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean for a system of equations to be consistent?

Back

A system is consistent if it has at least one solution.

Front

What is the difference between a linear function and a nonlinear function?

Back

A linear function has a constant rate of change (straight line), while a nonlinear function does not.
