Write an equation for each line in slope-intercept form.

Answers

Answer:

y = x + 7

Step-by-step explanation:

The slope-intercept form of a line is:

y = mx + b

where m is the slope and b is the y-intercept.

Looking at the graph, we can see that the line intersects the y-axis at y = 7. So 7 would be our y-intercept.

To find the slope, we would divide the rise of the line by the run. Or m = rise/run. From looking at the graph, we can see that for every 1 unit the line moves in the x-direction, the line moves in the y-direction by 1 unit. Therefore, the rise would be 1 and the run would be 1. 1/1 = 1 so the slope of the line would be 1.

Plugging in 7 for b and 1 for m into the equation for the slope-intercept form, we get:

y = x + 7

So that would be the equation for the line in slope-intercept form.

A. The Clear-Picture Cable Company charges different rates for ordering different levels of cable service. Clear-Picture Cable Company charges $24.95 a month for basic cable services plus $6.95 a month for each additional premium channel. If Stacey's monthly bill is $45.80, how many premium channels is she receiving? Write and solve and equation to answer the question. Show all work.


B. Dan signed a contract for 12 months of basic cable service with 2 premium channels each month. Dan budgeted $400 for this year's cable expenses. EXPLAIN whether Dan budgeted enough money to cover the yearly cost for his cable contract.


(please answer with all work and a full explanation for B. THANKS SO MUCH!!)

Answers

Answer:

A. 3 premium channels

B. No, he did not

Step-by-step explanation:

1a. make an equation that shows the price Stacey has to pay each month. x is how many premium channels she's paying for.

  24.95 + 6.95x = 45.8

2a. subtract 24.95 from both sides.

  6.95x = 20.85

3a. divide both sides by 6.95.

  x = 3

1b. make an expression to show the price of Dan's contract. (keep in mind, he has to pay for 2 premium channels for 12 months, so you would have to pay for the premium channels 24 times!)

  24.95(12) + 6.95(24)

2b. multiply.

  299.4 + 166.8

3b. add.

  $466.20

Dan would have to pay $466.20, so no, he did not budget enough money.

Who to tell if the question is rational or irrational

Answers


An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point. Any number that can be written as a fraction or a ratio is a rational number. The product of any two rational numbers is therefore a rational number, because it too may be expressed as a fraction.

d is ur answer maybe ok ok ok

Answer:

B. N(n+8)

Step-by-step explanation:

A rectangle's area is Length x Width

The rectange's length is not known to us. N is it's variable

It says the width is 8 units mor then the length and ask for the are of the rectangle.

Now since rectangle's area is length times width we multiply n (the length) with the width (8+n).

This would be N(n+8)

mass is dropped onto the mat from a height of 1 m above the mat. During the impact,
the cylinder’s vertical velocity reaches zero at the instant the mat has compressed to
only 4 cm thick.

a. How much kinetic energy does the cylinder have at the instant just before it
contacts the mat?

b. How much work does the mat do to stop the fall of the cylinder?

c. What average vertical force does the mat exert on the cylinder during the impact,
from contact until the cylinder’s vertical velocity is zero?

Answers

Answer:

A)196J

B)-208J

C)3467J

Step-by-step explanation:

We are given that a 20 kg cylindrical  mass is dropped onto the mat from a height of 1 m above the mat. During the impact,  the cylinder’s vertical velocity reaches zero at the instant the mat has compressed to  only 4 cm thick.

So, The Mat gets compressed by : 10cm - 4 cm = 6 cm=0.06 m

a)

Using Conservations of energy

Potential energy at the top = Kinetic energy at the point before touching the surface

Kinetic energy = mgh= [tex]20 \times 9.8 \times 1 = 196 J[/tex]

b)

Work done  by the mat do to stop the fall of the cylinder =[tex]-mg(h+0.06)=-20 \times 9.8(1+0.06)=-208 J[/tex]

C)

Work done=[tex]\text{Average force} \times \text{ Compression of mat}[/tex]

Reese loves to drink healthy green smoothies. A 16oz serving of smoothie has 170 calories. How many calories are in a 24oz smoothie?

Answers

Answer:

255 calories.

Step-by-step explanation:

There are many different ways to solve this, but I only know two.

First I noticed that 16 and 24 were both divisible by 4 so divided 16 by 4 and got 4. Then I divided 170 by 4 and got 42.5. So then I divided 24 by 4 and got 6. I multiplied 6 by 255.

OR

Divide 170 by 16 which gave me 10.625 which is the unit rate or constant of proportionality. So I multiplied 10.625 by 24 and got 255.

Answers

Answer:   30%

Step-by-step explanation:

Pie eaten by Anita = 30%

Pie eaten by Bob = 40%

total Pie = 100%

Pie left for by Sheila = 100 - (30 + 40)

                                 =  100 - 70

                                  = 30%

Sohie’s mom cans jelly. She fills each jar with 1/2 a pint of jelly. If she made 1 7/10 pints of jelly, which expression can be used to find how many jars Sophie’s mom can fill?

Answers

Answer:

Number of jar Sohie's mom can make can be found out by dividing the total amount by the amount in one jar, so we can frame a equation like this,

Let the number of total jar be x,

x = (1 7/10) / 1/2

That is the answer, let us solve this equation,

x = 1 7/10 / 1/2

=> x = 17/10 * 2/1

=> x = 17/5 * 1/1

=> x = 17/5

17/5 = 3.40

Therefore, she can pack 3.4 jars of jelly.
