-0.6 should be subtracted from 3
You have used the Distributive Property to transform numerical expressions such as (5)(3) + (2)(3) to (5 + 2)(3). How would you transform 5x + 2x into a single term? Substitute five different values into the expressions 5x + 2x and 7x - 1. What do you notice about the values of the expressions? Is there any value that would make the two expressions equal? Why or why not? No Response(s) Be the first to respond to the Discussion topic!

Answer:
see below
Step-by-step explanation:
we take out a common term (factor) from the expressions /numbers which are being added . In the given expression 5x + 2x , the common factor is x , so we can write it as x(5+2) .
Now we can add 5 and 2 inside the brackets that would be 7 , so in single term it would be 7(x) = 7x .
Substituting 5 different values
In 5x + 2x1. put x = 0 , 5*0 +2*0 = 0 + 0 = 0
2. put x = 1 , 5*1+2*1 =5+2 = 7
3. put x = 2 , 5*2+2*2 = 10+4 = 14
4. put x =3 , 5*3+ 2*3 = 15+6 = 21
5. put x=4 , 5*4+2*4 = 20+8 = 28
In 7x -11. put x = 0 , 7*0 -1 = -1
2. put x = 1 , 7*1-1 = 6
3. put x = 2 , 7*2 -1 = 13
4. put x =3 , 7*3-1 = 20
5. put x=4 , 7*4 -1 = 27
For any value that makes them equal ,
equate the given equations ,
5x + 2x = 7x -1
7x = 7x -1
7x -7x = -1
0 = -1
thus we arrived at a contradiction, so there won't be any values for which the equations will be equal. Also we notice that for same values the result of 2nd equation is one less than equation 1.
And we are done!

Is the function y = -1/2 + 1/10x linear or nonlinear? Check the attachment below
Answers
A customer at a shipping store is planning to send a package and is considering two options. The customer can send a package for $3, plus an additional $2 per pound. The cost, y, can be represented by the equation y = 3 + 2x, where x represents the amount of pounds of the package. Another option is that the customer can pay a one-time fee of $17 to send the box, represented by the equation y = 17.
Based on the graph of the system of equations, when will the cost of the two shipping options be the same?
A: A package that weighs 10 pounds will cost $17 for both options.
B: A package that weighs 7 pounds will cost $17 for both options.
C: A package that weighs 17 pounds will cost $31 for both options.
D: A package that weighs 17pounds will cost $37 for both options.
Answers
Answer: B
Step-by-step explanation:
the question is what number do you replace X with to make Y equal 17.
the two equations are Y=3+2X and Y=17
we want to know what x equals when y is 17 so in the first equation we can replace y for 17 that gives the equation 17=3+2x
next you will minus 3 from both sides which would make the equation 14=2x
then you will divide both sides by 2 and that will give the equation 7=x
this makes the answer B because if the pacage weight is 7 then y will equal 17
put y=2x in a table place eeeeeeeeeeeeeeeeee

B) r=5
Step-by-step explanation:
7r - 7 = 2r + 18
= 7r - 2r = 18 + 7
= 5r = 25
= r=5
The value of expression is,
⇒ r = 5
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 7r - 7 = 2r + 18
Now, We can simplify as;
⇒ 7r - 7 = 2r + 18
⇒ 7r - 2r = 7 + 18
⇒ 5r = 25
⇒ r = 25/5
⇒ r = 5
Thus, The value of expression is,
⇒ r = 5

Data was collected on the amount of time that a random sample of 8 students spent studying for a test and the grades they earned on the test. A scatter plot and line of fit were created for the data.

Determine the equation of the line of fit.
y = 5x + 60
y = 5x + 80
y = 10x + 60
y = 10x + 80
Answers
Answer:
y = 10x + 60
Step-by-step explanation:
So, the chart coordinate should looks like this:
(1, 75)
(2, 70)
(3, 80)
(4, 95)
(4, 100)
And there is a line passing (0, 60) and (2, 80)
So we just need to find the y-intercept and the slope by the line:
Slope: [change in x over change in y] = 20 ÷ 2 = 10
y-intercept: [the value of y when x equal 0] = 60 (because the line passed through (0, 60) )

33) A student has a set of cards, Each cara nas a picture of one shape.
The table shows the number of cards that have a picture of each
shape. The student will randomly select one card from the set.
Shape Cards
Circle = 8
Pentagon = 12
Rectangle = 10
Square = 6
Triangle = 4
Which statement is true?
A) The probability of selecting a card with a picture of a circle is 5/8, and the probability of selecting a card that is not a picture of a circle is 3/8
B) The probability of selecting a card with a picture of a circle is 3/8, and the probability of selecting a card that is not a picture of a
circle is 5/8
C) The probability of selecting a card with a picture of a circle is 1/5, and the probability of selecting a card that is not a picture of a
circle is 4/5
D) The probability of selecting a card with a picture of a circle is 4/5, and the probability of selecting a card that is not a picture of a circle is 1/5
Answers
Answer: C The probability of selecting a card with a picture of a circle is 1/5, and the probability of selecting a card that is not a picture of a
circle is 4/5
Step-by-step explanation:
First you need to find the total amount of cards in the set by adding up all of the cards: 8 + 12 + 10 + 6 + 4 = 40
Then to find the probability of selecting a circle divide the number of cards that have a circle by the total number of cards: 8/40
You can simplify it to be 1/5 since 8/8 = 1 and 40/8 = 5
So the probability of a circle is 1/5
This means that the probability for all of the other shapes that are not a circle have to be 4/5-- but you can check by adding up the rest then dividing by 40:
12 + 10 + 6 + 4 = 32
32/40 --> 32/8 = 4 & 40/8 = 5
4/5

The height of a cylinder is 4 millimeters. The circumference of its base is 10pi mm.
a. What is the radius of the cylinder? Explain.
b. Find the volume of the cylinder to the nearest tenth.
Answers
Answer:
Solutions below.
Step-by-step explanation:
Cylinder FormulasLets define the required formulas for the question regarding the cylinder.
The base of the cylinder is a circle, therefore the formula for the circumference of the base is:
[tex]2\pi r[/tex]
The formula for the volume of the cylinder is:
[tex]\pi r^{2} h[/tex]
Questiona) Given from the question, the circumference of the base is [tex]10\pi[/tex] mm.
Therefore, we can use the circumference formula to find radius of the base.
[tex]2\pi r = 10\pi \\2r = 10\\r = \frac{10}{2} \\r = 5mm[/tex]
b) With all the parameters given, we can find the volume of the cylinder.
Volume of the Cylinder =
[tex]\pi r^{2} h\\= \pi (5)^{2} (4)\\= 100\pi mm^{3} \\= 314.2mm^{3} (nearest\ tenth)[/tex]
