Domain is the set of values that you can input in a function
Range is the set of values that corresponds to the output of a function, the set of values corresponding to its results
The vertical line test is a simple test you can do with a graph to know if this graph correspond to a function or not: you have to draw a vertical line, parallel to the y-axis and if that line touch the graph in just one point, it is a function
What is the domain and range of each function?
Domain = {3, 5, 7, 8, 11}
Range = {6, 7, 9, 14}
Is each relation a function?
Yes

$1200 each month
Step-by-step explanation:
So Craig pays $720 each year, so he pays 720/12 = $60 each month
Since $60 is 1/20 of his monthly income, we multiply 60 by 20
60* 20 = 1200
Craig earns $1200 each month

A pipe is leaking at 1.5 cups per day. About how many gallons per week is the pipe leaking? (Hint: 1 gallon=16 cups)
Answers
Answer:
21/32 gal
Step-by-step explanation:
1 gallon equals 16 cups, so we first need to convert the rate from cups to gallons
1.5cup/1 x 1/16 gal
can be simplified to 3/32 gal
so we now multiply this rate by 7 for a week
so in total it leaks
3/32 x 7/1 = 21/32

Data for length of the tail (in millimeters) and age (in days) of tadpoles is entered into a statistics software package and results in a regression equation of ŷ = 15 - 1.5x.
What is the correct interpretation of the slope if the length of the tail is the response variable and the age is the explanatory variable?
Answers
Using the slope concept, it is found that the correct interpretation is that each day, the length decreases by 1.5 millimetres.
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which
m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.b is the y-intercept, which is the value of x when y = 0.In this problem, the length of the tail, in millimetres, after x days, is given by:
[tex]y = 15 - 1.5x[/tex]
The slope is of [tex]m = -1.5[/tex], which means that each day, the length of the tail decreases by 1.5 millimetres.

Solve the inequality
-5/2(3x-2)<6-2x.
Show and explain every step.
Answers
Answer:
its true the answer is true but would u need a whole Paragraph like an explanation I could make one for you.
The solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).
What is inequality?
inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
Given inequality will be solved as below:-
( - 5 / 2 ) ( 3x - 2 ) < 6 - 2x
Multiply the other hand by 2 and solve further.
( - 5 ) ( 3x - 2 ) < 2 ( 6 - 2x )
( - 5 ) ( 3x - 2 ) < ( 12 - 4x )
Take like terms to the same side and solve.
-15x + 30 < 12 - 4x
-15x + 4x < 12 - 30
-11x < - 18
x < 18 / 11
Therefore, the solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).
