Answer:

Price in dollars = $3 * number of comics

Step-by-step explanation:

Yes , they do show a relationship

Looking at the table, we can observe that if we multiply the number of comics by 3 , we get the price in dollars

What this is saying is that the cost of 1 comic is $3

The equation is thus;

Price = $3 * number of comics

Answer: X= -15

Step-by-step explanation:  

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer: 4r = 4

Step-by-step explanation:

Ruth bought 4 rulers and each ruler is to be represented by r. She therefore bought:

= 4r

She bought these for a total of $4.00 so the equation then becomes:

4r = 4.00

Equation representing situation is: 4r = 4

Answer:

C

Step-by-step explanation:

Remark

A midsegment is 1/2 the size of the side that it is parallel to.

Equation

6x - 6 = 2*(x + 3)                    Remove the brackets

6x - 6 = 2x + 6                       Subtract 2x from both sides

6x - 2x - 6 = 6                        Combine

4x - 6 = 6                               Add 6 to both sides

4x = 6 + 6                              Combine

4x = 12                                   Divide by 4

x = 12 / 4

x = 3

Find DF

But that's not the answer.

DF = x + 2

DF = 3 + 2

DF = 5

Answer:

2

Step-by-step explanation:

Answer:

(8, - 5 )

Step-by-step explanation:

Given the 2 equations

3x + 4y = 4 → (1)

- x - 3y = 7 → (2)

Multiplying (2) by 3 and adding to (1) will eliminate the x- term.

- 3x - 9y = 21 → (3)

Add (1) and (3) term by term to eliminate x, that is

0 - 5y = 25

- 5y = 25 ( divide both sides by - 5 )

y = - 5

Substitute y = - 5 into either of the 2 equations and solve for x

Substituting into (1)

3x + 4(- 5) = 4

3x - 20 = 4 ( add 20 to both sides )

3x = 24 ( divide both sides by 3 )

x = 8

solution is (8, - 5 )

sorry mine was a mistake

Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out.

Number of students that want a beef meal = 12

Number of students that want a chicken meal = 8

Number of students that want a pasta meal = 5

Total number of students = 12 + 8 + 5 = 25

The prediction of the meals wanted by the 200 students will be:

Beef meal = 12/25 × 200 = 96

Chicken meal = 8/25 × 200 = 64

Pasta meal = 5/25 × 200 = 40

Answer:

1) Slope, m = 2, y-intercept, b = 5 ↔ y = 2·x + 5. 2) Slope, m = 3, y-intercept, b = 5 ↔ y = 3·x + 5. 3) Slope, m = 5, y-intercept, b = 4 ↔ y = 5·x + 4. Step-by-step explanation: The equation of a straight line in slope and intercept form is given as follows; y = m·x + b. Where; m = The slope. b = The y-intercept. 1) When m = 2 and b ...

Step-by-step explanation:

1/-2 i think i would need to see the graph to be sure

The answer is: 4%  

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 5750 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 5750, so we can write it down as 100%=5750.

4. We know, that x% equals 230 of the output value, so we can write it down as x%=230.

5. Now we have two simple equations:

1) 100%=5750

2) x%=230

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=5750/230

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 230 is what percent of 5750

100%/x%=5750/230

(100/x)*x=(5750/230)*x       - we multiply both sides of the equation by x

100=25*x       - we divide both sides of the equation by (25) to get x

100/25=x

4=x

x=4

now we have:

230 is 4% of 5750

answer is 5/10-4/10= 1/10 sorry if im wrong

Answer:

[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]

Step-by-step explanation:

equation of line formula:

[tex]y = mx + c[/tex]

m = slope

c = y-intercept

1) find m

slope formula:

[tex]m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} [/tex]

take 2 coordinates from the given graph and substitute the values into the slope formula

i) (-1,0)

[tex]x _{1} = - 1[/tex]

[tex]y_{1} = 0[/tex]

ii) (3,2)

[tex]x_{2} = 3[/tex]

[tex]y_{2} = 2[/tex]

substitute the values into the slope formula

[tex]m = \frac{2 - 0}{3 - ( - 1)} [/tex]

[tex]m = \frac{2}{4} [/tex]

[tex]m = \frac{1}{2} [/tex]

2) find the half equation of the line by substituting the value of m into the equation of line formula

[tex]y = \frac{1}{2} x + c[/tex]

3) find c by substituting either coordinate into the half equation

(3,2)

x = 3

y = 2

[tex]2 = \frac{1}{2} (3) + c[/tex]

[tex]2 = \frac{3}{2} + c[/tex]

[tex]2 - \frac{3}{2} = c[/tex]

[tex] \frac{1}{2} = c [/tex]

[tex]c = \frac{1}{2} [/tex]

4) find equation of line by substituting the value of c into the half equation

[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]

Answer: Eva's dog actually gained 3/8 pounds ( 0.375pounds)

Step-by-step explanation:

Step 1

Given that

old weight = 1 7/8  pounds

New weight = 2 1/4 pounds

weight gained = New weight - Old weight

Step 2

 weight gained = New weight - Old weight

                  2 1/4  pounds - 1 7/8 pounds

      2.25 pounds - 1.875 pounds

         0.375pounds = 3/8 pounds
