Please plot this linear equation on a graph, and also explain how to plot it.
[tex]y=3x-7[/tex]

Answers

Answer 1

Answer:

See below:

Step-by-step explanation:

Hello! I hope you are having a nice day.

We can solve this equation in a single step, we just need a bit of theory and a graph.

We can first see that its in [tex]y=mx+b[/tex] form. Which is also known as Slope-Intercept form.

This means that we know the following.

[tex]b[/tex] is the y coordinate of the y intercept.[tex]m[/tex] is the slope of the line.

Since we know that, we can see that from our equation that the slope of the line is 3 and the y intercept is (0,-7).

Now that we've gotten that, we can start graphing.

The y intercept is -7 so we can plot (0,-7) as one of our points.

The slope of 3 means that we got up 3 units then right a single unit.

Therefore, another point could be (1,-4).

With our two points, we can create our graph by creating a straight line through those two points and therefore plotting our line.

Cheers!

Answer 2

Answer:

Step-by-step explanation:

y = 3x - 7 is a linear equation with y-intercept -7 (or    (0, -7)   ) and slope 3.  These two quantities are instantly readable from the equation.

There are several ways in which we may graph this equation.  One is to plot the y-intercept (0, -7)  Then choose an x-value, such as 3, and evaluate the function at that x value.  We see that y = 9 - 7, or y = 2, when x = 3. Then another point on the graph besides (0, -7) is (3, 2).  Plot (3, 2) and then draw a line through the two plotted points.

Here's another way:

The slope here is 3, or 3/1, which represents rise / run.  Plot (0, -7) as before.

Move your pencil from (0, -7) 1 space to the right and 7 spaces up.  Then plot a new point at that location.  Draw a line through (0, -7) and (1, 0).

I think it’s C sorry if it’s wrong

Answer:

The answer is B

Step-by-step explanation:

You can turn them into improper fractions

so

[tex]10 \frac{1}{2} = \frac{21}{2} [/tex]

[tex]2 \frac{1}{4} = \frac{9}{4} [/tex]

when we divide we invert the second fraction

[tex] \frac{21}{2} \div \frac{9}{4} = \frac{21}{2} \times \frac{4}{9} [/tex]

now we can multiply as usual

[tex] \frac{21}{2} \times \frac{4}{9} = \frac{84}{18} [/tex]

[tex] \frac{84}{18} = \frac{14}{3} = 4 \frac{2}{3} [/tex]

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a radius of 13 feet and a height of 14 feet. Container B has a radius of 10 feet and a height of 18 feet. Container A is full of water and the water is pumped into Container B until Conainter B is completely full.

After the pumping is complete, what is the volume of water remaining in Container A, to the nearest tenth of a cubic foot?

Answers

Answer:

The percentage ≅ 48.4%

Step-by-step explanation:

The volume of water left in container A = 2197π - 1134π = 1063π feet³

* To find the percentage of the water that is full after pumping

 is complete, divide the volume of water left in container A

 by the original volume of the container multiplied by 100

∴ The percentage = (1063π/2197π) × 100 = 48.3841 ≅ 48.4%

A tire from Karens car is shown below Which is closest to the distance traveled, in feet, after 3 full rotations of the tire? use pi= 22/7

Answers

Answer:

264 inches

Step-by-step explanation:

Circumference = pi x diameter

28 x 22/7 = 88 (in)

88 x 3  = 264 (in)

The closest distance traveled by Karen's car is, 18.86 feet.

What is Circle?

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We know that;

One rotation of the tire is equal to the circumference of the tire.

And, The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd

where, π = 22/7

d = diameter

Here, The size of one revolution = 2 x 22/7

                                                   = 44/7 feet

Hence, The distance covered in one rotation of the tire is 44/7 feet

So, The distance covered in 3 rotations = (44/7) x 3

                                                             = 18.86 feet

Excerpt from To Build a Fire This passage is an excerpt from Jack London's famous short story describing the experience of a man hiking in the middle of an extremely cold winter morning. With his faithful companion a husky dog, the man and the dog walk through the winter morning hoping to meet his associates later that day. All this the man knew. The oldtimer on Sulphur Creek had told him about it the previous fall, and now he was appreciating the advice. Already all sensation had gone out of his feet. To build the fire he had been forced to remove his mittens, and the fingers had quickly gone numb. His pace of four miles an hour had kept his heart pumping blood to the surface of his body and to all the extremities. But the instant he stopped, the action of the pump eased down. The cold of space smote the unprotected tip of the planet, and he, being on that unprotected tip, received the full force of the blow. The blood of his body recoiled before it. The blood was alive, like the dog, and like the dog it wanted to hide away and cover itself up from the fearful cold. So long as he walked four miles an hour, he pumped that blood, willynilly, to the surface; but now it ebbed away and sank down into the recesses of his body. The extremities were the first to feel its absence. His wet feet froze the faster, and his exposed fingers numbed the faster, though they had not yet begun to freeze. Nose and cheeks were already freezing, while the skin of all his body chilled as it lost its blood. But he was safe. Toes and nose and cheeks would be only touched by the frost, for the fire was beginning to burn with strength. He was feeding it with twigs the size of his finger. In another minute he would be able to feed it with branches the size of his wrist, and then he could remove his wet footgear, and, while it dried, he could keep his naked feet warm by the fire, rubbing them at first, of course, with snow. The fire was a success. He was safe. He remembered the advice of the oldtimer on Sulphur Creek, and smiled.
