What is the domain of the function on the graph? Ans: all real numbers
Elias and Niko are polishing the silver at the heritage museum. Elias
could polish all the silver himself in 40 minutes. That task would take
Niko 50 minutes to complete alone. Which table is filled in correctly and
could be used to determine how long it would take if Elias and Niko
polished the silver together? Ans: A
Line JK passes through points J(-3, 11) and K(1, -3). What is the
equation of line JK in standard form? Ans: 7x + 2y = 1
What is the inverse of the function f(x) = 4x + 8? Ans: h(x)=1/4x-2
The tables represent the functions f(x) and g(x).
Which input value produces the same output value for the two functions?
Ans: x = -6
Yesterday, Selma read 75 pages of her book. If she reads at a pace of 2
pages per minute today, which table shows only viable solutions for the
total number of pages she has read, y, after x minutes have elapsed?
Ans: D
What is the solution to 4|0.5x - 2.5| = 0? Ans: x = 5
Which table represents a direct variation function? Ans: D
Which is the graph of linear inequality 6x + 2y > -10? Ans: A
Using a stopwatch, Tyrone determines it takes him 58.2 minutes to travel
30 miles to work. The stopwatch measures to hundredths of a minute.
Going by the accuracy of the stopwatch, which is the most accurate
determination for the number of feet per second Tyrone traveled on his
way to work?
, Page | 2
1 mile = 5,280 feet Ans: 45.36 feet per second
Which are points on the graph of y = 1.5 + ⌈x⌉? Select three options
Ans: (-4.5, -2.5)
(7.9, 9.5)
(1.3, 3.5)
Which statement is true about the end behavior of the graphed function?
Ans: As the x-values go to negative infinity, the function's values go to
positive infinity.
A function g(x) is defined as shown.
g(x) =
What is the value of g(4)? Ans: 12
Percy works two part-time jobs to help pay for college classes. On
Monday, he works 3 hours at the library and 2 hours at the coffee cart
and earns $36.50. On Tuesday, he works 2 hours at the library and 5
hours at the coffee cart and earns $50. His hourly wage at the library, x,
and hourly wage at the coffee cart, y, can be determined using the
system of equations below.
3x + 2y = 36.502x + 5y = 50.00
At which job does Percy earn the greater hourly wage? How much does
Percy earn each hour at this job? Ans: Percy earns a greater hourly
wage of $7.50 at the library.
Marlena created a table of values representing the height in feet, h(t), of
a coconut falling to the hard ground with a height of 0 feet, collected over
t seconds. Assume the coconut does not bounce.
Which statement is true? Ans: The values of h(t) when t = 4 and 5
should be 0.
How many intersections are there of the graphs of the equations below?
