Answer 1

Answer:

x = -5  y = -3

Step-by-step explanation:

-3x + 2y = 9

multiply the 2nd equation by 3 to set it up for elimination

3(x - 3y)= 3(4)

3x-9y = 12

so now combine both to add

-3x + 2y = 9

3x - 9y = 12

Adding both gives you

-7y = 21

divide both by -7 and you get

y = -3

and you substitute y back into equation to get x

x - 3 (-3) = 4   gives you

x + 9 = 4

x = 4 - 9

x = -5

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

PLS SOMEBODY ANSWER IM DESPERATE I NEED AN ANSWER OMGGGG I WILL GIVE BRAINLIEST JUST ANSWERR!!! maria earns $4.76 an hour at the local supermarket. each week, 25% of her total pay is deducted for taxes. in addition, she pays $25 a week, after taxes, in union dues. if she wants her takehome pay to be at least $100 a week, how many hours must she work? show work pls :)

Answers

Step-by-step explanation:

Let x be the number of hours Maria work per week.

We have 0.75 * $4.76x - $25 >= $100.

Therefore 0.75 * $4.76x >= $125,

$4.76x >= $166.66

x >= 35.014

Hence Maria have to work at least 36 hours per week.

Which of the following would be a possible solution to the system of inequalities given below?

(3,-3)
(1,-7)
(6,4)
(-5,0)

Answers

Answer:

(3, -3)

Step-by-step explanation:

A point qualifies as a solution to a system of inequalities if it is true when both of its x and y values are substituted into the both inequalities. Knowing this, let's plug in the first option, (3, -3), into both inequalities.

Let's try 6x + 3y > 3 first. Substitute 3 for x and -3 for y:

[tex]6 (3) + 3 (-3) > 3\\18 - 9 > 3\\9 > 3[/tex]

9 is bigger than 3, so (3, -3) is a solution to that inequality.

Let's try [tex]x -y \geq 4[/tex]. Do the same, substituting the same values:

[tex]3 - (-3) \geq 4\\3 + 3 \geq 4\\6\geq 4[/tex]

6 is bigger than 4, so (3, -3) is a solution to that inequality too.

Since (3, -3) is a solution to both inequalities, it must be the answer.

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

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.

Factoring

We are given a trinomial:

The following steps are done to factor the trinomial.

1. Confirm there are no common factors: No common factors (given)

2. Factor out -1:

Multiply all the terms by -1 and take -1 out:

[tex]\boxed{(-1)(x^2+x-6)}[/tex]

3. Factor

[tex]x^2+x-6 = (x+p)(x+q)[/tex]

We have to find two numbers p and q whose product is -6 and the sum is 1. Those numbers are 3 and -2 (in any order):

Factoring:

[tex]x^2+x-6 = (x+3)(x-2)[/tex]

The final factoring is:
