Answers
Answer: D. X = 6 maps to y = 2
Step-by-step explanation:
i guessed and got it right lol
The option that does not represent another possible mapping in the relation is x = 6 maps to y = 2.
This mapping is not possible because we can not have the same inputs for different outputs.
y = 4 when x = 6 (given)
Option D is the answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Function:
A function can have the same output for different inputs.
A function can not have different outputs for the same inputs
Now,
y = 4 when x = 6.
Other possible mappings are:
A.
x = 4 maps to y = 6
This mapping is possible.
B.
x = 3 maps to y = 2
This mapping is possible.
C.
x = 0 maps to y = 0
This mapping is possible.
D.
x = 6 maps to y = 2
This mapping is not possible because we can not have the same inputs for different outputs.
y = 4 when x = 6 (given)
E.
x = 1 maps to y = 6
This mapping is possible since we can have different inputs for the same outputs.
Thus,
The option that does not represent another possible mapping in the relation is x = 6 maps to y = 2.
This mapping is not possible because we can not have the same inputs for different outputs.
y = 4 when x = 6 (given)
Option D is the answer.

wash 10 loads of dishes?
Answers
Answer:
❤️
Step-by-step explanation:
Answer: It would be 80 gallons of water that the dishwasher will use to wash 10 loads of dishes. To figure this out you would need to divide 32 by 4 which would equal 8. You would do this to figure out how many gallons of water a dishwasher needs to wash 1 load of dishes. Then you would multiply 8 times 10 which would equal 80.

PLEASE HELP WILL MARK BRAINLIEST (if possible).......................Braden bought 18 pencils for $4.50. Let x represent the number of pencils purchased, and let y represent the total cost. Graph the line that represents the proportional relationship.
Answers
Answer:
We are given x represent the number of pencils purchased, and let y represent the total cost.
We also given 18 pencils for $4.50.
Therefore, cost of each pencil = 4.50/18 = $0.25
Total cost (y) = cost of each pencil × number of pencils.
Therefore, equation would be
y = 0.25x.
In order to graph it, let us find some points for graph using table.
Plugging x=4, we get
y = 0.25(4) = 1.
Plugging x=8, we get
y = 0.25(8) = 2.
We got two coordinates, (4,1) and (8,2).
Plotting those points on the graph and joining the points.
We can see that graph represents the proportional relationship.

Answer:
a) ∠BAC = 30°b) ∠B = 120°c) ∠BAG = 150°Step-by-step explanation:
2x + 18 = 5x
18 = 5x - 2x
3x = 18
x = 6
a) find m∠BAC
substitute x=6 to ∠BAC
∠BAC = 2x + 18
= 2(6) + 18
= 30°
b) find m∠B
∠B = 180 - ∠A - ∠C
= 180 - 30 - 30
= 120°
c) find m∠BAG
∠BAG = 180 - ∠A
= 180 - 30
= 150°

Answer:
0.45 = 9/20
0.88 = 22/25
Step-by-step explanation:
Answer:1. 9/20
2. 22/25
Step-by-step explanation:
The decimals are in the hundredths place, which means the denominator should be 100. To make it 100, divide the numbers by 100
45 / 100 = 45/100
88 / 100 = 88/100
Then, you can easily simplify.
45/100 = 9/20
88/100 = 22/25

What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
