Answer:
6. [tex]\pi = \frac{C}{2r}[/tex]
7. Translation
Step-by-step explanation:
6: To solve for π means to isolate it on one side.
Step 1: Divide both sides by 2r.
[tex]\frac{C}{2r} = \frac{2\pi r}{2r}[/tex] [tex]\pi = \frac{C}{2r}[/tex]Therefore, π = circumference over twice the radius, or circumference over diameter.
7: #7 is a translation because each point is moving vertically 3 units and horizontally 1 unit (3 units up and 1 unit to the right). If it were a reflection, we'd be able to spot a line of reflection, but there isn't any here. Also, if it were a rotation, the triangle would change the way its angled, and it'd be in a different quadrant
Therefore, this is a translation.

Therefore, we need to find the slope (“m”) of the line (change in y/change in x), which is rise/run. We also need to find the y-intercept (“b.”)
1.) (0, -3) (1, -1)
We took two points from the line to find the slope. We will use the 2 coordinate pairs to find the slope.
2.) m=(y2-y1)/(x2-x1)
This is the slope “m” formula.
3.) m=( -1+3)/(1-0)
Input the coordinate values into the formula. The +3 you see is due to -(-3)=+3.
4.) m=2/1
We simplified the above formula.
5.) m=2
By division.
We now have the slope or “m.” M=2. Therefore, the equation rises 2 units and runs 1 unit.
Now, finding the y-intercept:
The y-intercept or “b” is where the line intersects the y-axis. It is the starting point of a linear equation.
To find the y-intercept, we need to figure out what the output is when the input is 0. We can see on the table in the picture that with an input of 0, the output is -3.
Therefore, b=-3. This is because an input of 0 means that there is no movement on the x-axis, so we can determine where the where the linear intercepts the y-axis.
Therefore, the equation is y=2x-3, where m=2 and b=-3.
That’s the answer: y=2x-3

What is the rate of return when 10 shares of Stock
A, purchased for $15/share, are sold for $210? The
commission on the sale is $6.
Rate of Return = [?] %
Give your answer as a percent rounded to the
nearest tenth
Answers
10 shares at 15 each is 150$ that it costed you to buy. You sold it for 210$ so you gained 54$ (60$ minus the 6$ commission).
Set up a proportion: 150/100 = 210/x. x=136% or your investment returned you 36% of your initial 150.

2x - 19
Step-by-step explanation:
Perimeter = sum of sides
First let's simplify each side
We can simplify each side by using distributive property. Distributive property is where you multiply the number on the outside of the parenthesis by the numbers on the inside of the parenthesis.
2(x + 5)
Distribute by multiplying x and 5 by 2
2 * x = 2x and 2 * 5 = 10
2x + 10
1/2(4x + 8)
Distribute by multiplying 4x and 8 by 1/2
1/2 * 4x = 2x and 1/2 * 8 = 4
2x + 4
-3(2x + 11)
Distribute by multiplying 2x and 11 by -3
-3 * 2x = -6x
-3 * -33
-6x - 33
Finally add all the simplified expressions ( remember that they represent the side lengths of the triangle )
2x + 10 + 2x + 4 - 6x - 33
Combine like terms
2x + 2x - 6x = -2x
10 + 4 - 33 = -19
Perimeter: -2x - 19

For her phone service, Yolanda pays a monthly fee of $12, and she pays an additional $0.05 per minute of use. The least she has been charged in a month is $63.80
What are the possible number of minutes she has used her phone in a month? Use m for the number of minutes, and solve your inequality for m.
Answers
Answer:
Step-by-step explanation:
12 + 0.05m = 63.80
12 + 1m/20 = 63.8
12 + m/20 = 63.8
(20 * 12)/20 + m/20 = 63.8
(20 * 12 + m)/20 = 63.8
(m + 240)/20 = 63.8
20((m + 240)/20) = 63.8
m + 240 = 20 * 63.8
m + 240 = 1276
m = 1276 - 240
m = 1036
order -.48, -.47, -.45, -.46 from least to greatest pls
Answers
Answer:
-0.48, -0.47, -0.46, -0.45
Step-by-step explanation:
Initially, you may think to put -0.45 as the least value out of the four. However, we are dealing with negatives. This changes the way we order the numbers.
Here's what you need to know:
The closer a negative number is to 0, the greater it is. The farther a negative number is to 0, the less it is. For instance, -1 is a lot closer to being a positive number as opposed to -14.
Now, you apply that concept to this question.
-0.45 is the greatest since it is closer to 0 than -0.48!

How to find perimeter with equations
I attached a pic of the problem I’m really struggling with, if I could get a step by step explanation of how to do it that would be great. Thanks so much
Answers
Step-by-step explanation:
In blue colour square
Perimeter= 4 × side
= 4 (3x +7)
=12x +28 unit
In green colour square
Perimeter= 4 × side
= 4 ( 5x+1)
= 20x +4 unit
Answer:
12x + 28 = p
20x + 4 = p
Step-by-step explanation:
Assuming that both shapes are square, the perimeter of a square is the equation:
4 * x = p
Where x is the length of one side. Plug the variables in for the first square:
4 * (3x + 7) = p
Expand the brackets:
4 * 3x = 12x
4 * 7 = 28
12x + 28 = p
For the second square, plug the variables in again:
4 * (5x + 1) = p
Expand the brackets:
4 * 5x = 20x
4 * 1 = 4
20x + 4 = p
