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.

Step-by-step explanation:

What statements can be supported by data from the table? Check all that apply.
The table shows a partial representation of the equations.
(2, 3.1) is an ordered pair from the table.

For a relation where y is a function of x, y = 4 when x = 6. Which of the following does not represent another possible mapping in the relation?
Choose the correct answer below.
O A. x = 4 maps to y = 6
OB. x = 3 maps to y = 2
O C. X=0 maps to y = 0
OD. X = 6 maps to y = 2
O E. X = 1 maps to y = 6
help asap please.

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?

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.

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:

c = 3[tex]\sqrt{6}[/tex]

Step-by-step explanation:

triangle is right isosceles so both sides equal 3[tex]\sqrt{3}[/tex]

can use pythagorean theorem which is square each leg and set it equal to the hypotenuse (side 'c') squared

(3[tex]\sqrt{3}[/tex])^2 +  (3[tex]\sqrt{3}[/tex])^2 = c^2

(9x3) + (9x3) = c^2

27 + 27 = c^2

54 = c^2

c = [tex]\sqrt{54}[/tex]

simplify  [tex]\sqrt{54}[/tex] to equal = [tex]\sqrt{9}[/tex] x [tex]\sqrt{6}[/tex] which simplies to 3[tex]\sqrt{6}[/tex]
