Answer:

undefinedx = Pdoes not exist0

Step-by-step explanation:

2. The x-value of the given points is the same, so the points both lie on the vertical line ...

  x = P

__

1. The slope of a vertical line is "undefined".

__

3. Given that P ≠ 0, the vertical line is parallel to the y-axis, so there is no y-intercept.

__

4. A line perpendicular to a vertical line will be horizontal. A horizontal line has a slope equal to zero.

A snow making machine priced at $1800 is on sale for 25% off. The sales tax rate is 6.25%. What is the sale price including tax? If necessary round your answers to the nearest cent.

Answers

Answer:

1434.375

Step-by-step explanation:

If you multiply 1,800 by 25% you get 1,350

you take 1,350 and add 6.25% because the 6.25% is the tax.

Then you will get 1434.37 or 1434.40

2.5(a + 4) + 0.5a = 12.4

Answers

Answer:

a=0.8

Step-by-step explanation:

First I distributed 2.5 into (a+4) and got (2.5a+10)+0.5a=12.4. I then combined like terms which are 2.5a and 0.5a and got 3a+10=12.4. I subtracted 10 from both sides to get rid of it and got 3a=2.4. Later, I divided 3 from both sides to get a which comes out to be 0.8.

Answers

Answer:

For solving x         x= -24+y/4  For solving Y                y=−24−4x

Step-by-step explanation:

This is solving for x

Add y to both sides.

−4x=24+y

Divide both sides by -4

and the answer is

x= -24+y/4

THis is solving Y

Add 4x to both sides

−y=24+4x

Multiply both sides by -1

Bob runs a total of 12 miles each week. He wants to increase the number of miles he runs each week by 1.5 miles until he is running a total of 26 miles each week. Provide an equation that can be used to determine the number of weeks Bob will need to reach his goal

Answers

Answer:

The equation is 12 + 1.5w = 26

Step-by-step explanation:

Each week running = 12 miles

He wants to increase the number of miles he runs each week by 1.5 miles until he is running a total of 26 miles each week.

12 + 1.5w = 26

Where,

w = number of weeks to reach his goal

12 + 1.5w = 26

1.5w = 26 - 12

1.5w = 14

Divide both sides by 1.5

w = 14 / 1.5

= 9.33 weeks

amount of storage space downloading it will take up. She starts the download and
notices it will download at a constant rate. After 3 minutes, she checks her phone
and sees that she has 2,345 MB of space available. She checks her phone after 7
minutes and notices that she now has 2,105 MB of space available.
(a) How many MB of available storage are being filled by the movie per minute?

Answers

Answer:

240

Step-by-step explanation:

by minusing the both values it'll be 240

The rate at which the storage space of the mobile gets filled by the movie is - 60 MB per minute.

Given that,
A student buys a movie to watch on her phone
it will download at a constant rate.
After 3 minutes, she checks her phone and sees that she has 2,345 MB of space available.
She checks her phone after 7 minutes and notices that she now has 2,105 MB of space available.

What is the rate of change?

The rate of change is defined as the change in value with the rest of the time is called rate of change.

Here,


Rate = (storage available after 3 minutes) - (storage available after 7 min)]
             ---------------------------------------------------------------------------------------------
                                              Time interval

Rate = (2,345 - 2105 ) / (3 - 7)
Rate = - 240 / - 4
Rate = - 60

Where negative sign shows that the amount of storage getting reduced.

Thus, the rate at which the storage space of the mobile gets filled by the movie is - 60 MB per minute.
