Answer:

y-inctercept=4, x-intecept=7

Step-by-step explanation:

I did it with the standard to slope again!

7y=28-4x

y=4-\frac{4}{7}x

Now don't get confused here, 4 is the y incetecept, not -4.

When y=0, x=7

UPDATE:

To determine x and y intercept using graph, see where the line intersects at the x or y axis.

Vaselesa [24]

Answer:

\boxed{r =  \frac{h}{3}  +  \frac{v}{\pi {h}^{2} } }

Step-by-step explanation:

Solve \:  for \:  r:  \\  =  >   v= \pi {h}^{2}(r -  \frac{h}{3}  ) \\  \\  v=\pi {h}^{2}(r -  \frac{h}{3}  )is \:  equivalent  \: to   \:   {h}^{2}\pi(r -  \frac{h}{3}  ) = v: \\  =  >  {h}^{2}\pi(r -  \frac{h}{3}  ) = v \\  \\ Divide  \: both \:  sides  \: by  \: \pi  {h}^{2} :  \\  =  > r -  \frac{h}{3}  =  \frac{v}{\pi {h}^{2} }  \\  \\ Add \:   \frac{h}{3}  \:  to  \: both \:  sides:  \\  =  > r =  \frac{h}{3}  +  \frac{v}{\pi {h}^{2} }

The amount of money raised at a charity fundraiser is directly proportional to the number of attendees. The amount of money rais
sattari [20]

Answer:

a. M=20A

b. k=20

c. $1200

Step-by-step explanation:

<u>Direct proportions </u>

Two variables are proportional if one of them is the other by a real number. That real number is called the Constant of proportionality. If x and y are proportional, then

y=kx, where k is the constant of proportionality.

The question describes the relationship between the amount of money raised at a charity fundraiser and the number of attendees. If they have five attendees, they raise $100

a.

Let's call A the number of attendees and M the amount of money raised, and

M=kA

We know that M=100 when A=5, so

100=k(5)

This means that  

k=20

The equation for the amount raised at the charity event is

M=20A

b.

The constant of variation is k=20

c. If there are 60 attendees (A=60), then

M=(20)(60)=$1200
