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) )

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

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

Step-by-step explanation: 12 to the third and 2 to the 6 times 3 to the third

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

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

Answer;

3 terms

Step-by-step explanation;

Just know that a number , a letter or both are terms.

6b is a term, a is a term and 1 is a term, the rest are plus signs.

so that makes 3 terms .

Step-by-step explanation:

Answer:

Solutions below.

Step-by-step explanation:

Lets 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]

a) 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]

Answer: 1/7 + 3/21 = 6/21

Step-by-step explanation:

1. Convert 1/7 to have a denominator of 21.    7 * 3 = 21

2. Multiply the numerator with the same number.   1 * 3 = 3

3. Add the new fraction straight across the top, leaving the bottom the same.

1/7 + 3/21 = 6/21

Answer:

[tex] \frac{2}{7} [/tex]

Step-by-step explanation:

Cancel out the second fraction because 7 is a multiple of 21.

1/7 + 1/7

Write the duplicate numerstors above the denominator

1+1/7

Add

1+1/7 = 2/7

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

1. 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

1. 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!
