Find the slope and y-intercept of y – 3x = 2

Answers

Answer:

slope is 3/1 y=2

Step-by-step explanation:

Slope: 3
Y-intercept: 2

Slope-intercept form can be represented as y=mx+b. The m is the slope and the b is the y-intercept. To get the equation into y=mx+b, add 3x to both sides to get the y by itself. When you add 3x to both sides you will get y=3x+2. The slope will be 3 because the 3 is in place of the m. The y-intercept is 2 because the 2 is in the place of the b.

chapter 13 medical math assignment sheet cengage learning a dental laboratory technician (DLT) earns $14 per hour when she works days and $18 per hour when she works nights. One month she works six 4-hour days, three 8-hour days, three 10-hour days, five 6-hour nights, and four 8-hour nights. What is her total pay for the month

Answers

Answer:

$2,208

Step-by-step explanation:

In order to calculate her total pay for the month we simply need to use the hours provided in the question, multiply each amount of hours by they pay rate for that day/night. Finally, we add all of the products together to get the final pay for the month.

6 * (4*14) = 336

3 * (8 * 14) = 336

3 * (10 * 14) = 420

5 * (6 * 18) = 540

4 * (8 * 18) = 576

336 + 336 + 420 + 540 + 576 = $2,208

Finally, we can see that her total pay for the month is $2,208

When you go swimming the pressure in your ears varies directly with the depth at which you swim. At 10 feet, the pressure is about 4.3 pounds per square inch (psi). a) Write the variation function. b) Predict the pressure at 50 feet. c) It is unsafe for amateur divers to swim where the pressure is more than 65 psi. How deep can an amateur swimmer safely swim (round to the nearest thousandth)

Answers

Answer:

(a) [tex]p = 0.43d[/tex]

(b) [tex]p = 21.5[/tex]

(c) [tex]d = 151.163[/tex]

Step-by-step explanation:

Given

Variation: Direct

Represent ear pressure with p and depth with d.

So, we have:

[tex]p\ \alpha\ d[/tex]

[tex]d =10[/tex] when [tex]p =4.3[/tex]

Solving (a): Write a variation

We have:

[tex]p\ \alpha\ d[/tex]

Write as an equation

[tex]p = kd[/tex]

Where: k is the constant of variation

[tex]d =10[/tex] when [tex]p =4.3[/tex]

So, we have:

[tex]4.3 = k * 10[/tex]

Make k the subject

[tex]k = \frac{4.3}{10}[/tex]

[tex]k = 0.43[/tex]

Substitute 0.43 for k in [tex]p = kd[/tex]

[tex]p = 0.43d[/tex]

Solving (b): Pressure at 50 feet

Substitute 50 for d in [tex]p = 0.43d[/tex]

[tex]p = 0.43 * 50[/tex]

[tex]p = 21.5[/tex]

The pressure is 21.5 pounds per square

Solving (c): The safe depth

The safe depth stops at a pressure of 65psi.

Substitute 65 for p in [tex]p = 0.43d[/tex]

[tex]65 = 0.43 * d[/tex]

Make d the subject

[tex]d = \frac{65}{0.43}[/tex]

[tex]d = 151.162790698[/tex]

[tex]d = 151.163[/tex] -- approximated

The safe distance for an amateur is 151.163ft

PLEASSSSSSSSSSSSS HELPPPPPPPPPPPPPPREAD THE PASSAGE THEN ANSWER THE QUESTIONSLast year, Ms. Perry, who taught fifth grade in Minneapolis, had read about the need for volunteers at a rural school in Africa. She applied and was accepted. Now it was summer break, and she was in Uganda. She was staying with Mr. Omara, a teacher at the school, and his family. When Mr. Omara showed her the school, she could not believe how many students were packed into the classroom. Students were seated on benches behind long tables and on the floor. She guessed there were ninety to a hundred students in one classroom! Ms. Perry worked with a small group of students as they practiced writing and speaking English. From her conversations with them, she learned about their lives. Ritah, Joseph, and Winnie got up at 5 a.m. and walked half a mile each way to collect water from the well before they walked to school. At night, they did their homework by candlelight. During her month in Africa, Ms. Perry learned that not only did schools need pens and paper, but books. Five students in a class shared one textbook. Mr. Omara explained that textbooks had to match the curriculum and be bought in Uganda. However, many storybooks in English were needed for reading practice. When Ms. Perry returned to Minneapolis, her class of 25 students looked small. She told them about the school she had visited. After she finished, Jackson said, The students need supplies and books, so we should collect these and send them to the school.Thats a great idea for a project, Victoria said. How can we get started? Ms. Perry said, Remember, we will need money for shipping expenses. If everyone lists their ideas for the project, we will talk about your ideas on Friday. On Friday, everyone was eager to share ideas. Eva had found a Web site that listed books needed in Uganda. Ms. Perry suggested they focus on fiction, or storybooks about made-up people and events. It would help students practice their skills in reading English. Logan pointed out that drop-off boxes for books could be placed in the front hall of the school and in the cafeteria. Everyone would see them there during lunchtime. Molly suggested publicity, saying they could make posters to get their information to the public. Ians idea was to collect books from families and neighbors and sell them in the shopping mall one weekend to make money. Molly drew a poster decorated with colorful books. It said, Bring your books to Parkside School for our book drive. From November 1 through November 15, we are collecting books to send to a school in Uganda. We need picture books and especially the books listed below. She printed the titles of the recommended books.At the bottom, it said, We are selling used books for adult readers to pay for our shipping charges. Stop by Vernon Mall on November 13 or 14.
