Answers

Answer 1

Answer:

rewrite equation 2 for x

x=8-7y

plug in x for equation 1

3/8*(8-7y)+1/3y=17/24

solve for y

3-17/24=21/8y-1/3y

55/24 = 55/24y

y=1

sub y back into eq. 2

x+7(1) = 8

x = 1

Which expression is equivalent to 2(a+3) when a=3?
O 2(3)
05(3)
O 2(3)+3
O 2(3)+6

Answers

Answer:

The answer is 2(3)+6

Step-by-step explanation:

The perenthesis means multiplication so you would first do 2 times three which is 6 and then 6+6=12 and the first expresion is 2(a+3) a=3 to solve that you would do whats in the perenthesis 3+3 which equals 6 and then the 6 in the perenthesis means mulitplication. so then you would do 2 times 6 and get 12. so the 3rd one is the answer.

identify the sequence 18,13,8,3,-2 PLZ HELPPPPP

Answers

The common difference between each term is -5. The nth term of the sequence as follows: aₙ = 18 - 5(n-1)

The given sequence is 18, 13, 8, 3, -2.

To identify the pattern in the sequence, we can observe that each term is decreasing by 5. Starting from 18, we subtract 5 to get the next term, and so on. The common difference between each term is -5.

Using this pattern, we can continue the sequence as follows:

-2 - 5 = -7

-7 - 5 = -12

-12 - 5 = -17

-17 - 5 = -22

The extended sequence would be -2, -7, -12, -17, -22.

In terms of the general formula, we can represent the nth term of the sequence as follows:

aₙ = 18 - 5(n-1)

What is the slope of a line perpendicular to Line AB given A (6,2) and B (-3,2)

Answers

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m of AB using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(- 3, 2)

m = [tex]\frac{2-2}{-3-6}[/tex] = [tex]\frac{0}{-9}[/tex] = 0

A line with a slope of zero is a horizontal line, parallel to the x- axis.

Thus a line perpendicular to AB is a vertical line parallel to the y- axis.

The slope of a vertical line is undefined

True or False? In reference to different sampling methods, systematic sampling includes the steps: list the members of the population; use simple random sampling to select a starting point in the population; let k = (number of individuals in the population)/(number of individuals needed in the sample); choose every kth individual in the list starting with the one that was randomly selected.

Answers

Answer:

True

Step-by-step explanation:

In the simple random sampling every individual in the population has an equal chance to be selected in the sample. Systematic sampling is a probability sampling in which selection of elements is made from order frame. These samples are selected based on intervals of the population.

A music store is receiving a shipment of Ipads. Each box comes with 12 white, 12 black and 24 grey
Ipads. They already have 23 white, 16 black and 22 grey Ipads. If the store is receiving 5 boxes, how
many of each color Ipad will they have?

Answers

Answer:

142 Grey, 83 white, 76 black

Step-by-step explanation:

If you were to take 5 boxes and put 24,12,12 in each, then multiply each number by 5 you wpuld get 120 Grey, 60 white and 76 black. Then you would add what they already have 120 Grey + 22 Grey is 142 grey, 60 white + 23 white is 83 white, and 60 black + 16 black is 76 black.

m = 5

Step-by-step explanation:

m + 3s = 50

m + s = 20

m + 3(20-m) = 50

m + 60 - 3m = 50

60 - 2m = 50

60 = 50 + 2m

60 - 50 = 2m

10 = 2m

5 = m

Mother Natures FuryTracy Wilson1 Looking back, I was sure that I was going to die that November afternoon. Tornado watches in Alabama are as common as eggs are for breakfast. So much so, that I had begun to ignore them altogether. This disregard for Mother Natures power nearly proved fatal for me and my sister. As we approached a fresh red light on a main thoroughfare through Huntsville, I glanced at the sudden peculiar coloring of the sky. The unusual hue and the stillness of the air gave me a sudden sense of uneasiness. The light changed and we made the left turn that would lead us home. It was after the turn that everything around me seemed to be occurring in slow motion. I heard it before I saw anything. At first I was sure that a train or a big truck was directly behind the car. Then I saw the debris, not the image of swirling winds we tend to associate with a tornado, but trash and wires and dirt. I remember a sudden feeling of weightlessness as we were lifted off of the ground. Strangely, she lifted us up like a feather on a breeze. It seemed more like floating than flying until she launched us from her grip with a fury few will ever understand.2 While I cannot remember the actual impact, pictures from the aftermath tell the story word for word. The tin can that once was a car was belly up in the top of a 100 foot maple. We hung there for hours, oblivious to the disaster around us. When rescuers could finally get to us, power lines made it too dangerous to touch the metal car. I awoke first 32 days after my ride in the sky and remembered much of the ordeal. My sister however, after lying in a coma for nearly three months, has no recollection of any detail from her life before the accident. Lack of oxygen erased her past. My physical wounds have long since healed, but I spend many hours below ground. The slightest hint of thunder or an awkward colored sunset sends me racing to my life below to hide from her.Which sentence would be the MOST accurate summary of this passage?A) Tornadoes are dangerous, unpredictable, and tremendously frightening. B) Everyone needs to take tornadoes seriously and always be prepared in case of severe weather. C) After barely surviving a tornado, the narrator now has a respect and even fear of nature's power. D) Tornadoes and hurricanes, while often confused, are actually not the same type of natural disaster at all. did she jump over the moon Estimate the total of 3,933+790+3,528+1,830 by adding the numbers and then rounding the result to the thousands place.
