Answer:

Step-by-step explanation:

The symbol that would go on the line would be the multiplication symbol. Because if you time 24 and 3/4 you get 18

Answer:

1. 24 x 3/4 = 18

2. 24 ÷ -3/4 = -32

3. 12 - 15 = -3

4. 12 - (-15) = 27

5. -18 ÷ -3/4 = 24

You could check and see if these work just in case but I hope they are correct.

Step-by-step explanation:

I hope you don't mind that there is no explanation. :)

And I also hope this helped and that I'm not too late.

Answer:

Since in your question you don't specify the coordinates of any of them, the best answer would be (-x, y) since that is the formula to find the reflection over the y-axis.

Answer:

525

Step-by-step explanation:

If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Answer: 25.12 ft

To find the circumference of a circle, multiply the diameter with π (pi)

Formula: 2πr (2 × radius) (π = 3.14)

In the problem...

-----------------------------------------------------------------------------------------------------------------

We can multiply 3.14 by 8 to get the circumference.

3.14 × 8 = 25.12

Hence, 25.12 is the answer, but we can do it another way.

Let me know if you have any questions.

Note to asker: Hi there, make sure to write down these formulas!

Circumference: 2πr

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!

Answer:

The solution is ([4], [19]).

Step-by-step explanation:

To solve the system of equations using the substitution method, we can follow these steps:Step 1: Start with the given equations:

y = 4x + 3 (Equation 1)

y = 7 + 3x (Equation 2)Step 2: Choose one of the equations and solve for one of the variables in terms of the other variable. Let's choose Equation 1 and solve for y in terms of x:

y = 4x + 3Step 3: Substitute the expression for y from Equation 1 into Equation 2 and solve for x:

4x + 3 = 7 + 3x (Substituting y = 4x + 3 from Equation 1)

4x - 3x = 7 - 3

x = 4Step 4: Substitute the value of x found in Step 3 back into either Equation 1 or Equation 2 to solve for y. Let's use Equation 1:

y = 4(4) + 3 (Substituting x = 4)

y = 19So the solution to the system of equations is x = 4 and y = 19. Therefore, the solution is ([4], [19]).

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

? = 110

Step-by-step explanation:

We know the one angle is 25 and the other is 45 because the 90 degree angle that is cut off perfectly in the middle.

All angles of a triangle always adds up to 180

Add all the known angles 25 + 45 = 70

Than subtract 180 - 70 = 110

Step-by-step explanation:

Step 1: Find the volume of tank 1

V= Lwh

l= 6in

w= 1.5in

h= 3in

6x1.5x3= 27

Step 2: Find the volume of tank 2

l= 2 in

w= 1.5 in

h= 9 in

2x1.5x9= 27

Step 3: Compare

27=27

answer= C

Explanation: Since they have the same volume, they can hold the same amounts. Using the formula V=lwh, I multiplied the lengths, widths, and heights of both tanks and then compared their volumes.

Answer:

y = x + 7

Step-by-step explanation:

This is a linear equation graph because the line is straight and it is going at a constant rate. You can just either add or subtract the dependent event or the y variable.  So I use the linear equation y = mx + b.

Use the y2 - y1 / x2 - x1 to find the slope. The slope is basically m.  You can use any coordinate for this.

I will use (2, 9) and (3,10) as the coordinates for an example.

So y2 = 10

y1 = 9

x2 = 3

x1 = 2

10 - 9 / 3 - 2 = 1/1 = 1

1 is the same thing as x.

So the slope is x.

Now in order to find b(or the whole number on the far right), you use one of the x and y coordinates.

For an example I will use (5, 12)

Now all I do is use the formula y = mx + b

y = 12

x = 5

m = 1.  M is the same thing as slope.

b is what I must find out.

So I write 12 = 1(5) + b

12 = 5 + b

Then you subtract 5 from 12

and you will get 7.

12 - 5 = 7

The b or the y intercept equals 7.

So the equation for this graph is y = x + 7

Simple bro! The hard part was the explanation.

The equation for the line is y=x+7

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

Given here, the points on the line are (2,9) , (3,10) , (4,11) , (5,12) , (6,13)

Let's assume the the equation of the line is y=x+7 then putting on the points on the equation we get

(2,9)  9=2+7

(3,10) 10=3+7

Similarly the equation holds good for all the points in the graph.

Hence, The equation for the line is y=x+7

Step-by-step explanation:

the rate of change or slope is the factor of x, when we have the function in the form y = ...

so, it is 2.

that means y changes by 2 whenever x changes by 1.

Answer:

\(x=\frac{1}{r} +1\)

Step-by-step explanation:

\(r=\frac{1}{x-1}\)
\(r(x-1)=1\)
\(x-1=\frac{1}{r}\)
\(x=\frac{1}{r} +1\)

Answer:

\(x=\dfrac{1+r}{r}\)

Step-by-step explanation:

Given equation:

\(r=\dfrac{1}{(x-1)}\)

Multiply both sides by (x - 1):

\(\implies r(x-1)=\dfrac{1}{(x-1)} \cdot (x-1)\)

\(\implies r(x-1)=1\)

Expand the brackets:

\(\implies rx-r=1\)

Add r to both sides:

\(\implies rx-r+r=1+r\)

\(\implies rx=1+r\)

Divide both sides by r:

\(\implies \dfrac{rx}{r}=\dfrac{1+r}{r}\)

\(\implies x=\dfrac{1+r}{r}\)
