Write a function in the form y = mx + b for the line that passes
through the points (2, 4) and (6, 16).

Answers

y=3x-2 i believe is the answer i did y2-y1 divided by x2-x1 which is 16-4 divided by 6-2 and 16-4 is 12 and 6-2 is 4 and 12/4 is 3 so 3 is your slope (m) so to find b you chose either (2,4) or (6,16) either one will work and i chose (6,16) then your plug in 16 for y and 6 for x so your equation is 16=3(6)+b then 3(6) is 18 so your new equation is 16=18+b then you subtract 18 from both sides to isolate b and 16-18 is -2 so your final equation is y=3x-2 you can do the same thing with the (2,4) point and end up with the same answer

Meg ate 3/8 pound of blueberries. Jon ate 7/8 pound of blueberries. How many more pounds did Jon eat than
Meg?

Please help me

Answers

Answer:

4/8 more pounds

Step-by-step explanation:

7/8-3/8=4/8

Answer:

Jon ate 5/8 more pounds of blueberries than Meg.

Step-by-step explanation:

This is because the question is asking for the difference between how many blueberries Meg ate, and how many Jon ate. Therefore, we have to use subtraction.

7/8 - 3/8 = 5/8, therefore Jon ate 5/8 lb more than Meg.

A bag contains exactly three red marbles, five yellow marbles and two blue marbles. If three marbles are drawn from the bag without replacement, what is the probability that all three will be the same color? Express your answer as a common fraction

Answers

Answer:

11/120

Step-by-step explanation:

Red = 3Yellow = 5Blue = 2

Possible options would be red or yellow as only two blue marbles.

Probability of 3 red:

3/10*2/9*1/8 = 1/120

Probability of 3 yellow:

5/10*4/9*3/8 = 1/12

Probability of same three is:

1/120 + 1/12 = 11/120

now do -3 * -1 and get 3 because two neg. = posit.

so now the question should say

4096+3= 4099-7= 4092

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Step-by-step explanation:

Given

The attachment

Required

Express the area as a sum of stores and parking lots

First, calculate the area of the stores

[tex]Store\ A = 25\ by\ 10[/tex]

[tex]Store\ B = 25\ by\ w[/tex]

[tex]Stores\ A\ and\ B = 25\ by\ 10 + w[/tex]

The area is then calculated as:

[tex]A_1 = 25 * (10 + w)[/tex]

Next, calculate the area of the parking lots

From the attachment, we have the following

[tex]Parking\ lot\ A = 13.5\ by\ 10[/tex]

[tex]Parking\ lot\ B = 13.5\ by\ w[/tex]

[tex]Parking\ lots\ A\ and\ B = 13.5\ by\ 10 + w[/tex]

The area is then calculated as:

[tex]A_2 = 13.5 * (10 + w)[/tex]

The area of the shopping centre is then calculated as:

[tex]Area = A_1 + A_2[/tex]

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

If y varies directly as x and x=2 when y=−4, find y when x=−6.

Equation: ____________

Solution: y = ___________

Answers

Answer:

Equation: x × -2 = y

Solution: y = 12

Step-by-step explanation:

if (x = 2) is (y = -4) then (x = 1) is (y = -2) so if (x = -6) is (y = 12) if we follow the equation [x × -2 = y] which was found using the first set of variables and dividing each by 2.

c. subtract from 100% with percentages, subtract from 1 with decimals.

Step-by-step explanation:

a. To find the percentage of red and yellow, skip back the decimal point two times: 0.26 > 26% 0.04 > 4%

Add all of the percentages together to get 70%

b. To find how many times more students said red than yellow, divide yellow from red. It shows you how many times yellow can go into red, giving you the correct answer.

0.26 ÷ 0.04

26 ÷ 4

c. 14% + 26% + 40% + 4% = 84%

100% - 84%

16%

C. Find the absolute risk reduction.

Answers

Answer:

Reduced/depressed

courageously/daringly

Boost/inflate

Explanation:

The following statement displays the recommendation of National Football League's(NFL) rule to wear new and lighter helmets by the players to diminish the chances of head injury during collisions between players. However, it has led the players to play more brazenly and fearlessly that eventually may cause the expansion of the number of collisions suffered by NFL players due to the valiant behavior of the players. This equates the ratio and leading to no improvement in the reduction of injuries among them even after this rule.

Please answer quickly! merry christmas (: Read the story.Life on the Sea The storm roiled on the horizon as rough waves rocked the helm of the fishing vessel. The captain had known the storm was cominghe had watched the weather reports for the past several days of the journeybut he started to question his decision as the waves got more powerful. One wave slapped the vessel and knocked him to the deck; when he stood up on unsteady feet, he grabbed the wheel with both hands. Though he had been a fishing boat captain for years and knew that the sea was the safest place for a vessel in a storm, these moments always terrified him. He had spent most of his life on the sea; he knew the habits and nuances of the water like it was his closest friend. The calmness that he felt when the water was placid wasnt like any stillness that he experienced on land. And though he didnt like the choppy waves when he could barely stay upright, he knew that these moments were necessary too. It was like lifein order to get to the peace, he had to weather the storm. His wife, Marla, didnt understand his obsession with the water, why he spent months of the year navigating a boat full of crab fishermen to isolated spots of the ocean hundreds of miles from shore. She couldnt grasp why he didnt get the same satisfaction from life behind a deskthe stable job in an office downtown that Marla wanted him to have. He had tried things her way, but that had only lasted a couple years; after a while, she could tell that he was miserable, and she gave him her permission to do what he loved. He gave his job two weeks notice and was back on the sea right away. He knew he missed things while he was away on these fishing boats: he listened to his wifes voice over an unreliable cell phone connection. Hed had to watch his daughter Ky speak her first words on a video that chirped into his phone. And though hed been there for her first steps, hed missed her first day of preschool, and there would inevitably be other milestones that he would miss. He stared into the blackness of the storm and knew that the fishermen below deck were relying on him to get them safely back to their familieshe knew this because he was aware of how his own family relied on him. He knew that he had to stay focused, even when he wanted to think about what his wife was doing now. He would see her in a weekand hed be able to take his daughter to school again. Hed be able to go to the grocery store and the park and do all the everyday things that he missed while at sea. He touched the picture of his family that was inside his raincoat as the next wave approached. He imagined their voices telling him that they were proud of him, and it filled him with a strength that he hadnt felt at other times during this journey. In the morning, the storm would die down, and he would enjoy the quiet. In the morning, he would call his daughter and tell her about the big storm and hear the wonder in her voice as he described the size of each wave. But for now, he was a man on a mission; he took a deep breath and held onto the steering wheel with every bit of his strength. Lets go, he thought as the biggest wave of all crashed into the boat.Question 1Part AIn the story "Life on the Sea," how does the captain mostly feel when he is on the sea?proudguiltyconfidentmiserableQuestion 2Part BWhich excerpts from the story best support the answer in Part A?Select the two correct answers."He gave his job two weeks notice and was back on the sea right away.""The calmness that he felt when the water was placid wasnt like any stillness that he experienced on land.""The storm roiled on the horizon as rough waves rocked the helm of the boat.""He had spent most of his life on the sea; he knew the habits and nuances of the water like it was his closest friend."
