1st box: 2

2nd box: 5

3rd box: 8

4th box: 11

5th box: 14

Step-by-step explanation: Plug in the formula y=3x+5. For example, you plug -1 as x, and you get y=(3)(-1)+5. 3 x -1 is -3, and then you add 5. The final answer is 2. Just do the same thing on the other boxes. Use the x values and plug it in into the formula shown.

All you have to do to find y is plug in the values of x given in the chart and onto the equation

1st: x = -1
y = 3x + 5
y = 3(-1) + 5
y = -3 + 5
y = 2

(-1, 2)

2nd: x = 0
y = 3x + 5
y = 3(0) + 5
y = 0 + 5
y = 5

(0,5)

3rd: x = 1 y= 8

4th: x = 2 y= 11

5th: x = 3 y= 14

Which of the following
represents a function?
PLEASE HELP 15 POINTS OR BRAINLIEST JUST ASK PLEASE HELP ME

Answers

Answer:

A: represents a function

Explanation:

Every other option, A,  has two y for one x.

It can be a function if there is 1x for 1y.

If this was helpful, please mark brainliest. Have a beautiful day!

Answer: Choice C (upper right corner)

Choice A is not a function because x = 2 leads to more than one y value (y = 1 and y = 7  at the same time)

Choice B is not a function for similar reasoning. Here we have x = 1 lead to y = 2 and y = 5 simultaneously.

Choice D is also not a function because of the two points (5,2) and (5,4). This tells us we have x =  5 lead to y = 2 and y = 4 at the same time.

A function is only possible if you have any input lead to exactly one output. Choice C shows this. Note how it passes the vertical line test. It is impossible to draw a vertical line through more than two points on the function curve.

Answer: the first one

Step-by-step explanation:

In math formulas, A and a, always represent the same number.

Answers

Answer:  False

Step-by-step explanation:

In math formulas, we want to use different symbols to represent different things.

While in linguistics, A and a represent the same thing, the symbols are different, then we can use them to represent different things.

For example, we can define a square of side length a.

And the area of that square will be equal to the square of its side length, we can represent the area with A, such that:

A = a^2.

Here A and a are different numbers (and also represent different measures, a is in units of length and A is in units of surface).

Then the statement is false.

which plan to purchase. Plan A has a monthly fee of $4995. Plan B costs $39.95 per month. Plan A

beyond 500 minutes. Which pair of equations could Tina use to decide on the least costly plan for her

(a) c = 39.95 + 0,10m - 300)
(b) c = 39.95 + 0.1(m - 500)
c = 49.95 + 0.050m - 500)
C = 49.95 + 0.05(m - 300)
(c) =3995+0.11 - 50
(d) =3995 +0.11 - 500

Simplify your answer.​

Answers

Answer:

[tex]\frac{4}{25}[/tex]

Step-by-step explanation:

Given expression:

          [tex]-\frac{1s }{20r}[/tex]  

   r  = [tex]-\frac{1}{4}[/tex] , s = [tex]\frac{4}{5}[/tex]

Now;

     [tex]-\frac{1s }{20r}[/tex]    = [tex]-\frac{s}{20r}[/tex]

              Insert the parameters:

                = [tex]-\frac{\frac{4}{5} }{20 x (-\frac{1}{4} )}[/tex]  

               = - [tex]\frac{\frac{4}{5} }{-5}[/tex]  

              -x - = +

                = [tex]\frac{4}{5}[/tex] x [tex]\frac{1}{5}[/tex]
