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?
A
Line JK passes through points J(-3, 11) and K(1, -3). What is the equation of line
JK in standard form?
7x + 2y = 1
What is the inverse of the function f(x) = 4x + 8?
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?
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?
D
What is the solution to 4|0.5x - 2.5| = 0?
x=5
Which table represents a direct variation function?
D
Which is the graph of linear inequality 6x + 2y > -10?
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?
1 mile = 5,280 feet
45.36 feet per second
Which are points on the graph of y = 1.5 + ⌈x⌉? Select three options
(-4.5, -2.5)
(7.9, 9.5)
(1.3, 3.5)
Which statement is true about the end behavior of the graphed function?
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)?

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?
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?
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?
1/2x + 5y = 6
3x + 30y = 36
