Consider the following graph and rotate point P 90° counterclockwise
around two points: the origin and (-2,4). Sketch both points on the
graph.

Answers

Answer 1

Answer:

[tex]P: (-2,4)[/tex]

[tex]P' : (-4,-2)[/tex]

Step-by-step explanation:

Given

[tex]P: (-2,4)[/tex]

Required

Rotate 90 degrees counterclockwise

Show both points on graph

[tex]P: (-2,4)[/tex]

When a point is rotated counterclockwise by 90 degrees, the new point is:

[tex]P':(-y,x)[/tex]

In

[tex]P: (-2,4)[/tex]

[tex]x = -2[/tex]

[tex]y = 4[/tex]

Hence:

[tex]P':(-y,x)[/tex]

[tex]P' : (-4,-2)[/tex]

You work at a grocery store part-time. You estimate that you spend three-fifths of your time stocking shelves. You work 20 hours each week. How many hours of your work week do you spend stocking shelves?

Answers

Answer: 12

Step-by-step explanation:

You spend 20 hours working at a grocery store each week. You spend 3/5 of that time stocking shelves. You need to find out what 3/5 of 20 is.

Step 1: Turn 20 into a fraction

20 = 20/1

Step 2: Multiply

3/5 x 20/1 = 60/5

Step 3: Simplify

60/5 = 12

Sam decides to download some new music. She downloaded 3 albums and 10
singles, and her total was $61. The next day she purchased more music from the
same retailer and downloaded 6 more albums and 8 singles for a total of $74.
Assuming that all albums and singles are the same price, how much did she spend on
each album and each single? Write a system of equations to represent this
situation. Then solve for the solution using the elimination method.

Answers

Answer:

An album costs $7 while a single cost $4

Step-by-step explanation:

Let the amount spent on singles be $x while the amount spent on albums be $y

First day, she downloaded 3 albums and 10 singles that cost $61

Hence;

3y + 10x = 61 ••••••••(ii)

Second day, she downloaded 6 albums and 8 singles for $74

8x + 6y = 74 ••••••••(ii)

We now want to use elimination method to solve both equations

Multiply equation i by 2 and ii by i

20x + 6y = 122

8x + 6y = 74

Subtract ii from i now

12x = 48

x = 48/12

x = 4

Recall;

3y + 10x = 61

substitute for x

3y + 10(4) = 61

3y + 40 = 61

3y = 61-40

3y = 21

y = 21/3

y = 7

An album costs $7 while a single cost $4

A. addition property of equality
B. subtraction property of equality
C. multiplication property of equality
D. division property of equality

Answers

The answer would be B

The addition property of equality was used to solve this equation. option A is correct.

A solution is given we have to determine the solution contains which property of equality.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
x − 5 = -14

x − 5 + 5 = -14 + 5

x = -9

We can see, in step 2 5 is added to both sides of an equality, which implies the property of additions.

Thus, the addition property of equality was used to solve this equation. option A is correct.

The image shows a 6-side polygon. The sum of the interior angles is:
