The equation that has a graph with a y-intercept of -8 is y =3x - 8. The correct option is A. y =3x - 8

To determine which of the given equations has a graph with a y-intercept of -8.

We will compare the equations with the slope-intercept form of the equation of a straight line.

The slope-intercept form of the equation of a straight line is

y = mx + c

Where m is the gradient or slope

and c is the y-intercept

By comparing with y = mx + c

m = 3 and c = -8

∴ The y-intercept here is -8

By comparing with y = mx + c

m = -8 and c = 3

∴ The y-intercept here is 3

This can be written as

y = (3/8)x + 5/8

By comparing with y = mx + c

m = 3/8 and c = 5/8

∴ The y-intercept here is 5/8

This can be written as

y = (8/3)x - 5/3

By comparing with y = mx + c

m = 8/3 and c = - 5/3

∴ The y-intercept here is -5/3

Hence, the equation that has a graph with a y-intercept of -8 is y =3x - 8. The correct option is A. y =3x - 8

Answer:

$0.15

Step-by-step explanation:

3÷20=$0.15

I hope this helps

The cost per message is $0.15

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Given that, a graph,

The graph is showing a straight line,

Considering a coordinate (3, 20),

That means, they cost $20 for 3 messages.

Therefore, for 1 message = 3/20 = 0.15

Hence, the cost per message is $0.15

Answer:1. 0.35. 0.35

Step-by-step explanation:

I did the question on edgenuity

The change for each consecutive time given is: 1

The change of each consecutive height given is: 0.35

The rate of change for the relationship between time and height is: 0.35

The table that displays the height of water when a pool is being filled against time is shown in the image attached. (See attachment).

Recall:

Rate of change can be calculated as: change in output / change in input

Change in output = difference between consecutive outputs

Change in input = difference between consecutive inputs

In the question given,

Time is input

Height is output

Thus:

Change for each consecutive input (time):

Therefore, the change of each consecutive input (time) is: 1

Change for each consecutive output (height):

Therefore, the change of each consecutive output(height) is: 0.35

Rate of change of the relationship between time and height:

Rate of change = change in height / change in time

Rate of change = 0.35/1 = 0.35

In summary:

The change for each consecutive time given is: 1

The change of each consecutive height given is: 0.35

The rate of change for the relationship between time and height is: 0.35

Answer:

y=9

Step-by-step explanation:

5(y-10)=-5

We move all terms to the left:

5(y-10)-(-5)=0

We add all the numbers together, and all the variables

5(y-10)+5=0

We multiply parentheses

5y-50+5=0

We add all the numbers together, and all the variables

5y-45=0

We move all terms containing y to the left, all other terms to the right

5y=45

y=45/5

y=9

The value of y = 9 is correct. Therefore, the solution is y = 9.

To solve the equation 5(y - 10) = -5 for y, follow these steps:

Step 1: Distribute the 5 on the left side of the equation:

5y - 50 = -5

Step 2: Move the constant term to one side by adding 50 to both sides:

5y - 50 + 50 = -5 + 50

Step 3: Simplify the left side and evaluate the right side:

5y = 45

Step 4: Isolate y by dividing both sides by 5:

5y / 5 = 45 / 5

Step 5: Simplify and calculate y:

y = 9

The solution to the equation is y = 9. To verify, substitute y with 9 in the original equation:

5(9 - 10) = -5

5(-1) = -5

-5 = -5

Since both sides are equal, the value of y = 9 is correct. Therefore, the solution is y = 9.

The statement that does not represent the same value as the others is 'the opposite of 9'

"It is the actual distance of the number from zero."

For given question,

We need to find the statement which does not represent the same value as the others.

We find the value for each statement.

a) the distance between 0 and 9

The distance between 0 and 9 is 9.

b) the absolute value of negative 9

We know, |-9| = 9

So, the absolute value of -9 is 9

c) the opposite of 9

The opposite of 9 is -9.

d) the absolute value of 9

|9| = 9

So, the absolute value of 9 is 9.

Therefore, the statement that does not represent the same value as the others is 'the opposite of 9'

Step-by-step explanation:

A rectangle's perimeter is given by the formula:

[tex]P=2(l+w)[/tex]

A rectangle's area is given by the formula:

[tex]A=lw[/tex]

We are given that they have the same numerical value. In other words:

[tex]2(l+w)=lw[/tex]

And we are also given that the length is 12 feet. So, substitute 12 for l:

[tex]2(12+w)=12w[/tex]

To solve for the width, we just need to solve for w.

On the left, distribute:

[tex]24+2w=12w[/tex]

Subtract 2w from both sides. The left side cancels:

[tex]24=10w[/tex]

Divide both sides by 10. Flip also:

[tex]w=\frac{24}{10}[/tex]

Reduce both layers. Use 2. So:

[tex]w=12/5=2.4[/tex]

So, the width is 2.4 feet.

The equation to find the proportion painted is: [tex]\mathbf{c = \frac{7}{8}x}[/tex]

Let the size of the art be x.

In the morning, she paints 3/4 of x.

So, we have:

[tex]\mathbf{Morning = \frac 34 x}[/tex]

In the evening, she paints 1/8 of x.

So, we have:

[tex]\mathbf{Evening = \frac 18 x}[/tex]

So, the amount of project painted is:

[tex]\mathbf{c = Morning + Evening}[/tex]

This gives

[tex]\mathbf{c = \frac 34x + \frac 18x}[/tex]

Take LCM

[tex]\mathbf{c = \frac{6x + x}8}[/tex]

Add the numerator

[tex]\mathbf{c = \frac{7x}8}[/tex]

So, we have:

[tex]\mathbf{c = \frac{7}{8}x}[/tex]

Answer:

x = 8

Step-by-step explanation:

Solve for x:

6 x + 9 = 4 x + 25

Subtract 4 x from both sides:

(6 x - 4 x) + 9 = (4 x - 4 x) + 25

6 x - 4 x = 2 x:

2 x + 9 = (4 x - 4 x) + 25

4 x - 4 x = 0:

2 x + 9 = 25

Subtract 9 from both sides:

2 x + (9 - 9) = 25 - 9

9 - 9 = 0:

2 x = 25 - 9

25 - 9 = 16:

2 x = 16

Divide both sides of 2 x = 16 by 2:

(2 x)/2 = 16/2

2/2 = 1:

x = 16/2

The gcd of 16 and 2 is 2, so 16/2 = (2×8)/(2×1) = 2/2×8 = 8:

Answer: x = 8
