The table shows how an elevator 500 feet above the ground is descending at a steady rate.

h(t) = 5t + 500

h(t) = 5t – 500

h(t) = –5t + 500

h(t) = –5t – 500

Which is the graph of linear inequality 6x + 2y > –10?

Option

Which graph represents the function g(x) = |x + 4| + 2?

Option

A function g(x) is defined as shown.g(x) = What is the value of g(4)?

Which system of linear inequalities has the point (2, 1) in its solution set?

y less-than negative x + 3. y less-than-or-equal-to one-half x + 3

y less-than negative one-half x + 3. y less-than one-half x.

Option

y less-than one-half x. y less-than-or-equal-to negative one-half x + 2

Which is the graph of y – 3 = (x + 6)?

Option

The function f(t) represents the cost to connect to the Internet at an online gaming store. It is a function of t, the time in minutes spent on the Internet.f(t) =Which statement is true about the Internet connection cost?

It costs $5 per hour to connect to the Internet at the gaming store.

The first half hour is free, and then it costs $5 per minute to connect to the Internet.

It costs $10 for each 90 minutes spent connected to the Internet at the gaming store.

Any amount of time over an hour and a half would cost $10.

Which graph shows the solution to the system of linear inequalities?2x – 3y <12y < –3

Option

Which graph represents the function y = 2x – 4?

Option

On a coordinate plane, a curved line with minimum values of (negative 2, 0) and (2.4, negative 51) and a maximum value of (negative 0.75, 6), crosses the x-axis at (negative 2, 0), (0, 0), and (3.5, 0), and crosses the y-axis at (0, 0).

As the x-values go to positive infinity, the function's values go to negative infinity.

As the x-values go to zero, the function's values go to positive infinity.

As the x-values go to negative infinity, the function's values are equal to zero.

As the x-values go to negative infinity, the function's values go to positive infinity.

Which linear function represents the line given by the point-slope equation y – 2 = 4(x – 3)?

f(x) = 6x – 1

f(x) = 8x – 6

f(x) = 4x – 14

f(x) = 4x – 10
