1. y=5x+3

2. y=5-3x

3. y=3x+5

It would be y=3x+5. This is because if it is going at a rate of 3cm a month, this makes it the constant value or the slope. But since it’s starting value is 5cm, that would make it the y-intercept, which is why your answer would be y=3x+5.

**Answer:**

y=3x+5

**Step-by-step explanation:**

The plant starts at 5cm so +5 is the starting height, It grows at 3cm a month making 3x the growth rate. so 3x+5 is the height of the plant every month.

Because of demand, concert tickets that normally sell for 89.99 each are marked up 20%, If Mark wishes to purchase 8 tickets, how much will he pay in total?

20 points will be given

Answer:$863.92

Step-by-step explanation:20% of 89.99 is 18

89.99x8=719.92

18×8=144

719.92+144=

863.92

**Answer:**

he will pay 864 dollars in total

**Step-by-step explanation:**

first we have to find 20% of 90 (i just rounded 89.99 to 90).

20% = 1/5, and 1/5 in decimal form is 0.20. (you can find the decimal value by multiplying the numerator and denominator by 10/10 and then simplifying it)

0.20 * 90 is 18, so we then add that to 90 making 108.

next, since Mark is buying 8 tickets, we multiply 108 by 8, giving us 864

**therefore, 864 is our final answer**

3. Given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solution. Show why this is true by solving the system of equations given. Justify the reason for each step. HINT: Use the addition property of equality and multiplication property of equality in your answers. (8 points: 1 point for each question)

5x + 2y = 7

3x – y = 2

To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)

Why is this multiplication allowed? (1 point)

What variable will be eliminated when the equations are combined after

the multiplication? (1 point)

Next, add the equations together. Your answer should be a single equation with one variable. (1 point)

Why can you add the equations? (1 point)

Solve the equation for x. (1 point)

Substitute x back into one of the equations to solve for y. (1 point)

What is the solution to the system of equations? (1 point)

**Answer:**

**Step-by-step explanation:**

To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)

5x + 2y = 7

**6x –2y = 4**

Why is this multiplication allowed? (1 point)

**Because the entire equation was multiplied by the same number, the equation remains the same.**

What variable will be eliminated when the equations are combined after the multiplication? (1 point)

**The Y variable**

Next, add the equations together. Your answer should be a single equation with one variable. (1 point)

**11x = 11**

Solve the equation for x. (1 point)

**X = 1**

What is the solution to the system of equations? (1 point)

**X = 1 and Y = 1 so the answer is (1, 1)**

**(If you solve this again, but eliminate the X variable, you will still receive that answer 1, so Y = 1)**

A. Are the expressions 3(m−2) + 2(m−2) and 5(m−2) equivalent expressions?

B. In two or more complete sentences, justify your answer to A.

The answer is yes. If you solve both expressions it would be 5m-10.

**Answer: yes, this is because when you solve the first equation then your answer will be 5(m-2). You do this by distributing 3 to m & 2 (multiply), then you will distribute 2 to m & 2 (also multiply). **

**Step-by-step explanation:**

Sam’s discount shoes is have a 40 percent off sale. A — use the percent ruler at right to find how much Lorna will save on her purchase of 80 dollar professional basketball shoes. B What will she pay for the shoes?

**Answer:**

A, 32

B, 48

**Step-by-step explanation:**

Since the discount is 40% off, she will save 40% of the 80 dollar shoes, which is 40% of 80 dollars. 40 * 80 = 3200, and 3200/100 = 32 dollars worth of savings. She will pay a total of 80 dollars minus the 32 dollar discount to get a total of 48 dollar payment.

**Answer:**

40% off that means her shoes will be 60% of the value so 80* 0.6 or 60% = $48 she will pay and 32 she will save

Solve for b.

b - 7 = -20

A. b = -27

B. b = -13

C. b = 13

D. b = 27

**Answer:**

B. b = -13

**Step-by-step explanation:**

b - 7 = -20

move variables and numbers to different sides of the equal sign by adding 7 to both sides

b - 7 + 7 = -20 + 7

b = -13

your answer would be -13 :) have a good day

When assessing whether product release deadlines were met during the first three months of the year, the quality assurance (QA) team noted that they were late 23 percent of the time. During that time, the team had hired two new specialists. The team immediately assessed their processes, including that of approving lot records, a required step to ensure that each lot met product requirements, which then triggered a product release. They found that the new QA reviewers were slow to make decisions because of lack of experience and knowledge. Which statement best explains why analyzing the lot record process and identifying the major constraint for product release was helpful to the QA director so she could take action to improve?a. Knowing what the constraint was helped the QA director to watch deadlines more closely as she is the one responsible for meeting them.b. Analyzing the root cause of the delays helped the QA director alert the new specialists that their work was not acceptable.c. Understanding what went wrong helped the QA director rethink her hiring policy and process so she could identify stronger candidates.d. Identifying the constraint informed the QA director of the need for increased training for the new specialists.
