You are recording an album at a music studio. You will be charged a $100 base fee and $50 an hour for each hour you use the studio. This function in function notation models the situation where h = the number of hours you rent the studio and c = the cost to rent the studio.
What is c(h) = 50h + 100
The inequality that models the following situation: "A test has multiple-choice questions worth two points each and constructed-response questions worth four points each. You need at least 40 points to pass. Let x = number of correct multiple-choice questions and let y = the number of constructed-response questions."
What is 2x + 4y ≥ 40?
The truthfulness of this statement: a number when written as a decimal never ends is irrational.
What is false?

What are 3 and 4?
In the sequence 20, 18, 16, 14,... this is the fiftieth term.
What is -78?
It just snowed you have 16 inches of snow in your front yard! You can't even open the door. If the snow melts at a rate of 2 inches per hour, this function in function notation models how many inches of snow are still frozen on your front yard where t is the number of hours since it stopped snowing and h is the height of the snow.
What is h(t) = 16 - 2t?
A test has multiple-choice questions worth two points each and constructed-response questions worth four points each. You need at least 40 points to pass. Let x = number of correct multiple-choice questions and let y = the number of constructed-response questions.
This one point of the following points is a solution: (-5, 18), (5, 8), (8, 5), or (8, -15)
What is (5, 8)?
The sum of these two of the following numbers is rational.
√50, 4.333333333..., √49, and 𝝅
What are 4.333333333... and √49?
The number that is added to complete the square for the equation x2 - 10x = 11
What is 25?
These are the roots of the function g(x) = x2 + 5x + 6
What are -2 and -3?
You are recording an album at a music studio. You will be charged a $100 base fee and $50 an hour for each hour you use the studio. This is the DOMAIN of this situation if the studio will charge you for the three hours if you use the studio for two hours and one minute?
What is positive integers/positive whole numbers/natural numbers/ h>0 such that h is an integer/whole number/natural number?
The solutions to the inequalities x + y ≤ -4 and 7x - 14y ≤ 0 are in these two quadrants.
What are II and III?
The product these two of following numbers is rational.
√5, √10, √15, √20
What is √5 and √20?

The factors of the expression 6x2 - 7x - 20
What are (3x + 4) and (2x - 5)?
It just snowed you have 16 inches of snow in your front yard! You can't even open the door. If the snow melts at a rate of 2 inches per hour, this is the DOMAIN of the function that models this situation.
What is 0 ≤ t ≤ 8 where t is a real number? Or [0, 8]...
The inequality 2x - 6y < 30 when converted into slope-intercept form looks like this.
The simplified version of the radical ∛(686w11)
What is 7w3 ∛(2w2)?
The equivalent equation to 6x2 - 24x = 54 when written in the form (x-a)2 = b
What is (x-2)2 = 13?
