How do i graph -7x-2y=-21???

Answers

Answer:

-7/2 is the slope. -10.5 is your starting point on the y-axis. You go from -10.5, up 7 and over to the left 2 times because it's negative.

Step-by-step explanation:

-7x-2y=-21

-2y=7x-21

y=-7/2x-21/2

y=-7/2x-10.5

Hope this helps!

You might want to simplify the equation first. Basically, we'll use y = ax+b instead.

[tex]-7x-2y=-21\\-2y=-21+7x\\y=\frac{-21}{-2}+\frac{7x}{-2} \\y=\frac{21}{2}-\frac{7x}{2}\\y=\frac{21-7x}{2}[/tex]

Should have been like this then you are able to graph.

To graph, you need to find the x-intercept and y-intercept.

(1) Find x-intercept, substitute y = 0

[tex]0=\frac{21-7x}{2} \\0=21-7x\\7x=21\\x=3[/tex]

Thus, the graph has a x-intercept at (3,0). For those who are wondering where does the fractional 2 go, just multiply the whole equation by 2 to get rid of the fraction.

(2) Find y-intercept, substitute x = 0

[tex]y=\frac{21-7x}{2}\\ y=\frac{21-0}{2}\\ y=\frac{21}{2} \\[/tex]

Also 21/2 = 10.5, Thus the graph passes y-axis at (0, 10.5)

Now plot the graph, make a line from x-intercept and y-intercept and you should get like this (Picture below.)

Solve v2 = 47.

please :)

Answers

Answer:

v=± 47=±6.8557

Step-by-step explanation:

(1): "v2" was replaced by "v^2".

(2) Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: v^2-(47)=0

The value of v is ± 6.856.

What is a perfect square ?

A number when taken square root gives an integer is a perfect square and when a number is not a perfect square and we have taken it's square root the number is an irrational number.

According to the given question v² = 47.

∴ v = ±[tex]\sqrt{47}[/tex].

We know that v is between 6 and 7 but more closer to 7 as [tex]\sqrt{49}[/tex] is ±7 and [tex]\sqrt{36}[/tex] is ±6 we we can write an approximate value of v which is ±6.9 or we can use a calculator for which v = ± 6.856.

The basic recipe for split pea soup serves 8 people. Find the amount of each ingredient needed to serve 32 people.

Answers

Answer:

Dried split peas: 9 cups

Water: 8 quarts

Chopped onion: 3 cups

Chopped celery: 4 cups

Ham shank: 8 pounds

Step-by-step explanation:

Since the basic recipe serves 8 people and you need to serve 32 people, you just multiply each ingredient by 4. (32÷8=4)

Dried split peas: 2 1/4 c.   x 4 = 9 cups

Water: 2 qt  x 4 = 8 quarts

Chopped onion: 3/4 c.  x 4 = 3 cups

Chopped celery: 1 c.   x 4 = 4 cups

Ham shank: 2 lb.  x 4 = 8 pounds

Emanuel can skateboard 3.375 miles against a 2-mph wind in the same amount of time he skateboards 6.375 miles with a 2-mph wind. Find the speed Emanuel skateboards with no wind.

Answers

Answer:

6.5 mph

Step-by-step explanation:

Given that :

Emanuel can skateboard 3.375 miles against a 2-mph wind in the same amount of time he skateboards 6.375 miles with a 2-mph wind. Find the speed Emanuel skateboards with no

Wind speed = 2mph

Let time taken to skateboard = t

Speed = distance / time

Distance of 3.375miles against 2 mph wind

Let skate speed = x

skate speed - wind speed=

(3.375 miles / t) + 2mph = x - - - (1)

Distance of 6.375miles with 2 mph wind

(6.375 miles / t) - 2 mph = x - - - - (2)

Equate (1) and (2)

(6.375/ t) - 2 = (3.375/ t) + 2

(6.375 - 3.375) / t = 2 + 2

3 / t = 4

3 = 4t

t = 3/4

t = 0.75

Hence, speed without wind will be :

(3.375 miles / 0.75) + 2mph = x

4.5mph + 2mph = 6.5 mph

They stopped when they heard the call, but looking round and seeing nobody, they went on again with their fighting, which now became more furious. He cried out again, and again they paused and looked about, but seeing no one went back to their fighting. A third time he called out, and then thinking he should like to know the cause of dispute between the three men, he went out and asked them why they were fighting so angrily with one another. One of them said that he had found a stick, and that he had but to strike it against any door through which he wished to pass, and it immediately flew open. Another told him that he had found a cloak which rendered its wearer invisible; and the third had caught a horse which would carry its rider over any obstacle, and even up the glass mountain. They had been unable to decide whether they would keep together and have the things in common, or whether they would separate. On hearing this, the man said, I will give you something in exchange for those three things; not money, for that I have not got, but something that is of far more value. I must first, however, prove whether all you have told me about your three things is true. The robbers, therefore, made him get on the horse, and handed him the stick and the cloak, and when he had put this round him he was no longer visible. Then he fell upon them with the stick and beat them one after another, crying, There, you idle vagabonds, you have got what you deserve; are you satisfied now! After this he rode up the glass mountain.What theme is explored in the story?A) Do not trust strangers. B) People will get what they deserve. C) Appearances can be deceiving.
