Is the following a function?
{-1,5), (2, 5), (3,5) (8,5)}

Answers

Answer 1

Answer:

Yes

Step-by-step explanation:

A function is where each x value maps to one y-value -> and that is true here.

Even though the 5 is repeated, different x-values are used, so that is okay.

It would just be a straight line.

Vertical Angles: Find the Supplementary Angles (photo provided)

Answers

Answer:

105°

Step-by-step explanation:

The given angles are vertical and congruent , then

8x - 21 = 6x + 3 ( subtract 6x from both sides )

2x - 21 = 3 ( add 21 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Then

6x + 3 = 6(12) + 3 = 72 + 3 = 75°

Supplementary angles sum to 180° , thus

supplementary angle = 180° - 75° = 105°

2y + 3y = 4 - 6 - 13

Answers

Answer:

y=-3

Step-by-step explanation:

2y+3y=4−6−13

2y+3y=4+−6+−13

(2y+3y)=(4+−6+−13)

5y=−15

5y=−15

y= −3

Answer:

y = -10

Step-by-step explanation:

You add 2y and 3y, you'd get 5y from it. You do 4-6-13 which is -15.

So 5y = -15.

You subtract 5 from the y side and add 5 to the -15.

So basically:

5y = -15

-5 & +5

y = -10

There are multiple answers this could be,

(x-18) (x)

(x-20) (x+2)

If you went with the first on (x-18) (x), then you wouldn't have to add anything.

(x-20) (x+2) = x^2 - 18X - 40.

Joleen is a sales associate in a clothing store. Each week she earns $250 plus a commission equal to 3% of her sales. This week her goal is to earn at least $460. What is the dollar amount of the sales that she must have to reach to get to her goal? Provide work.

Answers

Answer:

She must have to reach $7000 sales to get to her goal.

Step-by-step explanation:

Consider the provided information.

Let her weekly sales is represented by [tex]x[/tex].

Each week she earns $250 plus a commission equal to 3% of her sales. so this can be written as:

[tex]250+\frac{3}{100}x[/tex]

Her goal is to earn at least $460. It means she needs to earn more than or equal to $460.

[tex]250+\frac{3}{100}x\geq 460[/tex]

Now simplify it.

[tex]0.03x\geq 460-250[/tex]

[tex]0.03x\geq 210[/tex]

[tex]x\geq 7000[/tex]

She must have to reach $7000 sales to get to her goal.

You have 200 bottles of Medicine. 99% contain Medicine A; the rest, Medicine B. How many bottles of Medicine A do you need to use/empty to get Medicine A to 98%?

Answers

Answer:

I need to empty 2 bottles to get Medicine A to 98% of the total bottles

Step-by-step explanation:

The first step is to find out what 99% of 200 is. This will give us how many bottles of "Medicine A"  are present.

99% of 200 is 198. This means that there are 198 bottles of Medicine A present.

The next step is to find out what 98% of 200 is. This will give us the number of bottles of "Medicine A " that will be left remaining.

98% of 200 is 196. There neede to be 196 bottles left after I have taken out and emptied a few bottles of Medicine A.

The last step is to subtract 196 from 198 bottles, to get the number of bottles that I need to empty.

This will be 198 - 196 = 2 bottles

I need to empty 2 bottles to get Medicine A to 98% of the total bottles
