Answer:
The domain for A is 0, 1, 2, 3 and the range is 0, 5, 10, 15
and the domain for B is 2, 2, 4, 4 and the range is 4, 3, 2, 1
Only A is a function because for the same input value in B, there is two different output values which is not possible.
Step-by-step explanation:
I just wanna let you know so you don't waste any more points for us, but the domain is the x-values/ input/ stuff on the left of a given point. The range is the y-values, the output, and the stuff on the right side of a given point. So on (1, 7) for example, the 1 would be the domain number and the 7 would be the range number.
The y-axis values are the output/range and the x-axis values are the input/domain.
Hope this helps bro

A company rents out 11 food booths and 22 game booths at the county fair. The fee for a food booth is $125 plus $6 per day. The fee for a game booth is $80 plus $10 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answers
Answer:
$3135 + $286d
Step-by-step explanation:
Given that:
Food booth = 11
Game booth = 22
Let number of days = d
Food booth rent = ($125 + 6d) * 11
Game booth rent = ($80 + 10d) * 22
Food booth = $1375 + $66d
Game booth = $1760 + $220d
Amount company is paid :
Food booth rent + game booth rent
($1375 + $66d) + ($1760 + $220d)
$(1375 + 1760) + $(66d + 220d)
$3135 + $286d

This isn't something specific I need to know for school, I'm just curious. I know the most commonly used variables are x, y, and z. But what if you have more then three variables, what are the next letters you are supposed to use?
Answers
Answer:
Any letter you want
Step-by-step explanation:
The letters used for variables don't matter. What matters is what the variables represent: their numerical value. Variables are just to help identify what needs solving. Other common variables are a, b, and c which are found frequently in trigonometry. To answer your question, there are no "next letters." You can use any letter you'd like as a variable because it holds the same numerical value. Basically, the whole alphabet is at your disposal.
What is 12 = 1 + a/1 -a?
Answers
Answer:
There is no solution
Step-by-step explanation:
There are no values of (a) that make the equation true.
Answer:
a = 11/13
Step-by-step explanation:
Multiply both sides by 1 - a
12(1 - a) = 1 + a
= 12 - 12a = 1 + a
Subtract 12 from both sides
= -12a = -11 + a
Subtract a from both side
-13a = -11
Divide by -13 each side
-13a/13 = -11/-13
= a = 11/13

What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
Here, given that,

Square 7 and 14:
[tex]a^2 + 49 = 196[/tex]
Minus 49 from both sides:
[tex](a^2 + 49) - 49 = (196) - 49[/tex]
[tex]a^2 = 147[/tex]
Square root both sides:
[tex]\sqrt{a^2} = \sqrt{147}[/tex]
[tex]a = 12.12[/tex]
Therefore x is equal to 12.12

Given that,
Jonas was visiting Garner State Park. At the entrance, he saw a map of the park. The legend stated that 1.5 inches on the map represent 2.5 feet in the park. On the map, how many inches would represent 6 actual feet is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
On the map,
1.5 inches = 2.5 feet
1 feet = 1.5 / 2.5 inches
1 feet = 0.6 inches
Multiply both sides by 6.
6 feet = 3.6 inches
Thus, the required scale in inches for the 6 actual feet is 3.6 inches.
