The function f(x) = 2x2 + 2 represents the rate of a bus traveling in miles per hour. The function g(x) = x + 2 represents the t

ime the bus traveled in hours. Solve (f • g)(3), and interpret the answer.
(f • g)(3) = 100, the distance in miles the bus traveled
(f • g)(3) = 100, the number of buses
(f • g)(3) = 25, the distance in miles the bus traveled
(f • g)(3) = 25, the number of buses

Answer:

  (f • g)(3) = 100, the distance in miles the bus traveled

Step-by-step explanation:

The product of (miles/hour) and (hours) is (miles), so only answers with units of distance are applicable. The numbers are ...

  f(3) = 2·3² +2 = 20 . . . . miles per hour

  g(3) = 3+2 = 5 . . . . hours

so (f·g)(3) = f(3)·g(3) = 20·5 = 100 . . . . miles

This means only the first answer choice is applicable.

Please help!!!!!<br>Solve the equation 5(2y - 1) - 2(3y)= 1<br>​
-Dominant- [34]

Answer:

y = 3/2

Step-by-step explanation:

5(2y - 1) - 2(3y) = 1

First we use distributive property:

10y - 5 - 6y = 1

because 5 × 2y = 10y

and -2 × 3y = -6y

Now we combine the like terms:

4y -5 = 1

because 10y - 6y = 4y

Now we have to send the -5 to the other side. (when we send it to the other side it becomes positive because right now it is negative)

4y = 1 + 5

Again we combine the like terms:

4y = 6

(because 5 + 1 = 6)

Now we have to send the 4 to the other side because we need to get the y value. (when we send it to the other sidr it will be divided)

y = 6/4

and we simplify:

y = 3/2

And we cannot simplify or do anything else. So that is the answer.

Hope that helped!

Hello, please I will kindly ask if you take your time to help me with this math question
Finger [1]

Answer:

The answer to your question is below

Step-by-step explanation:

9)

They are supplementary angle. The sum of supplementary angles is 180°.

                   b + 50 = 180

-Solve for b

                    b = 180 - 50

                    b = 130°

10)

They are vertical angles. Vertical angles measure the same

                    b = 43°

11)

They are vertical angles. Vertical angles measure the same.

                    b = 73°

12)

They are supplementary angles. The sum of supplementary angles is 180°

                  b + 35 = 180

-Solve for b

                  b = 180 - 35

                  b = 145°
