A student is solving the equation 20x = 4(x – 8). Which describes a first step the student could use to solve the equation correctly?

The student can distribute 4 on the right side of the equation, resulting in 20x = 4x – 32.

The student can distribute 4 on the right side of the equation, resulting in 20x = 4x – 8.

The student can divide both sides of the equation by 4, resulting in 5x = x – 2.

The student can divide both sides of the equation by 4, resulting in 16x = x – 8.

A homeowner installs a fence around the perimeter of a pool. The perimeter of the pool is 81 feet, and the homeowner installs the fence in 3-foot sections. The function g(x) = 81 – 3x represents the number of feet remaining to fence after installing x amount of fencing sections. If 0 ≤ x ≤ 27, which statement is true about the function when graphed on a coordinate plane?

As x increases, the number of feet remaining to fence always decreases.

As x increases, the number of feet remaining to fence always increases.

As x increases, the number of feet remaining to fence decreases and then increases.

As x increases, the number of feet remaining to fence stays the same.

Consider the quadratic equation y = (x – 5)(x – 2). Which statement is true?

The point (0, 10) lies on the graph of the quadratic equation.

The point (−5, −2) lies on the graph of the quadratic equation.

The point (5, 2) lies on the graph of the quadratic equation.

The point (10, 0) lies on the graph of the quadratic equation.

The table shows the amount of dog food bags, y, a rescue center must purchase per month to feed x dogs.

There is a strong positive linear association.

There is a weak positive linear association.

There is a weak negative linear association.

There is a strong negative linear association.

Two bus drivers use linear functions to represent the amount of time it takes to complete each route, f(x) and g(x), and the number of stops per route, x. If 0 ≤ x ≤ 16, which statement is true?

The function representing f(x) has a greater slope and y-intercept than g(x).

The function representing f(x) has a greater slope but a smaller y-intercept than g(x).

The function representing f(x) has a smaller slope and y-intercept than g(x).

The function representing f(x) has a smaller slope but a greater y-intercept than g(x).
