Answers

Answer:

y = -2/3x + 5

Step-by-step explanation:

Find the slope by doing change in y / change in x:

-1 / 1.5 = -2/3

Then, put the equation in point slope form:

y - 5 = -2/3(x - 0)

y - 5 = -2/3x

y = -2/3x + 5

The math club is going to sell t-shirts as a fundraiser. They buy 100 t-shirts and pay a total of $600 for the t-shirts and printing costs.
If they sell each t-shirt for $12, how many t-shirts must they sell to make a profit of $300?
O A. 9
OB. 25
O C. 50
OD. 75
O E 100

Answers

i think the answer would be C

They have to sell D. 75 shirts to make a profit of $300.

The total cost of buying and printing the shirts was $600.

In order to make a profit of $300, they would therefore have to raise:

= Cost + profit

= 600 + 300

= $900

As they are selling each shirt $12, the number of shirts they would have to sell to get to $900 is:

= 900 / 12

= 75 shirts

They would therefore have to sell 75 shirts in order to make a profit of $300.

Answers

Answer:

x = 17

Step-by-step explanation:

number of sides (n) = 5

Sum of angles of polygon = (n - 2) *180

                                            = 3 * 180 = 540

9x + 71 + 92 + 5x + 139 = 540

9x +5x + 71 + 92 + 139 = 540

                   14x + 302   = 540

                               14x  = 540 - 302

                                14x = 238

Answers

Remember the are of a square is the side of a square squared.

This meant that this square's area=5^2=25

Done!

Sense it is a square all sides must be equal to each other
So each side is 5 ft
And to find the area of a square the formula is A=b•h
So A=5•5
Which gives you 25

ALGEBRA 2!!!!!!!HELP


Answers

Answer:

x = - 1, x = - 11

Step-by-step explanation:

Given

2| x + 6 | - 4 = 6 ( add 4 to both sides )

2|x + 6 | = 10 ( divide both sides by 2 )

| x + 6 | = 5

The absolute value function always gives a positive result, but the expression inside can be positive or negative, that is

x + 6 = 5 or - (x + 6) = 5

solve both

x + 6 = 5 ( subtract 6 from both sides )

x = - 1

or

- (x + 6) = 5 , that is

- x - 6 = 5 ( add 6 to both sides )

- x = 11 ( multiply both sides by - 1 )

x = - 11

Answer:Answer below in description:Step-by-step explanation:

Ths question is not complete but I will try my best to guide you through it so you can answer it. So what the question is asking you to do is that you have to plug in the coordinates into the equation. I don't want to give you an incorrect answer so I will explain it and you can do it yourself with the full question. First use the second equation as it is a full equation with an equal sign. Once plugged in you can find that c and d do not make the second equation true. A and B both complete the second equation. This means that either A or B is the answer. Since the first equation does not have an equal sign meaning it is not complete I can not answer it and I am sorry. But I have cut the answer down for you to A and B.

Bethany frowned at the dirt under her fingernails. She shrugged and plunged her fingers back into the upturned patch of soil in her front yard. She grabbed the soil in clumps and broke it through her fingers, letting the pieces fall back into the brown mounds. Once Bethany finished preparing her soil bed, she jumped up to go back in the house. Leaving a trail of dirt, she went to the kitchen and grabbed the seed packets. She was ready to bring the seeds to life. When Bethany stepped back outside, she saw a shiny bottle in the middle of her new flower bed. She went to pick up the litter and noticed soda has spilled into the soil. She looks like a hobo. The contemptuous voice seemed to float on the breeze, but Bethany knew where it came from. Sure enough, Viola was sitting on her porch with another girl from school. Seeing Viola sent a shiver through Bethany. They were friends as little kids, but in ninth grade, Viola had decided that she was better than everyone else. She always criticized Bethany, so they stopped being friends. Bethany felt her face tingle, but she kept her head down to focus on her work. She cleaned up the mess and carefully worked the seeds into place. After that, she dragged out the hose to soak the ground. Once she was finished, Bethany collapsed on the ground, hot and tired. Weeks later, bright flowersyellows, reds, pinks, and whitessprung to life. One afternoon, Bethany got home from school and was greeted with bad news. The night before, Viola had been in a car accident. She was in the hospital and would have to miss an entire semester of school. Bethany remembered how Viola had treated her weeks ago. Then, a stray memory popped up in her mind. She remembered a time that she cut her foot, and Viola carefully cleaned and bandaged the gash for her. Viola offered to do everything for Bethany so that she wouldnt have to walk. Bethany decided to visit that girl, and she arrived at the hospital room.
