To solve this equation, plug your input value into the function to find your output.

This would leave you with:
f(4)=4+21

Add the two integers together:
f(4)=25

So he output value of that function with he input of 4 would be 25.

Jen Butler has been pricing​ Speed-Pass train fares for a group trip to New York. Three adults and four children must pay $ 99. 
8090 [49]

Answer:

An adult ticket is 17

A childs ticket costs 12 dollars

Step-by-step explanation:

Let a = adult price

c = child price

3a + 4c = 99

2a + 3c = 70

Multiply the first equation by 2

2(3a + 4c) = 99*2

6a + 8c = 198

Multiply the second equation by -3

-3 (2a + 3c) = 70*-3

-6a -9c = -210

Add these new equations together

6a + 8c = 198

-6a -9c = -210

----------------------

     -c = -12

Multiply by -1

        c = 12

A childs ticket costs 12 dollars

Now we need to find the price of an adult ticket

2a + 3c = 70

2a + 3(12) = 70

2a +36 = 70

Subtract 36 from each side

2a +36-36 =70-36

2a = 34

Divide by 2

2a/2 = 34/2

a = 17

An adult ticket is 17

The formula for the volume of a sphere is v= 4/3 3.14rWhat is the formula solved for r?
prohojiy [21]

Answer:

r = \frac{3}{4\pi}V

Step-by-step explanation:

First, the formula for the volume of a sphere is:

V = \frac{4}{3}\pi r^3

\frac{3}{4}V = \pi r^3

\frac{3}{4}V\frac{1}{\pi} = r^3

r^3 = \frac{3}{4\pi}V

r = \sqrt[\leftroot{-2}\uproot{2}3]{\frac{3}{4\pi}V}
