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 - correct answer-45.36 feet per second
Which are points on the graph of y = 1.5 + ⌈x⌉? Select three options - correct answer-(-
4.5, -2.5)
(7.9, 9.5)
(1.3, 3.5)
Which statement is true about the end behavior of the graphed function? - correct
answer-As the x-values go to negative infinity, the function's values go to positive
infinity.

g(x) =
What is the value of g(4)? - correct answer-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? - correct answer-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? - correct answer-The values of h(t) when t = 4 and 5 should be
0.

1/2x + 5y = 6
3x + 30y = 36 - correct answer-infinitely many
The table represents a function.
What is the value of f(-1)? - correct answer-f(-1)=0
