Penelope leaves her house. For eight minutes, she drives to the store at a rate of one block per minute. Then, she stops for five minutes to shop in the store. Finally, she drives back to her house at a rate of four blocks every three minutes. Write the equation to model Penelope's trip to the store.

Answers

Answer 1

Answer:

T = 8 + 5 + 6

Step-by-step explanation:

Since it took Penelope 8 minutes to drive to the store at a rate of 1 block per minute then that means the store was 8 blocks away. That being the case if she drives back home from the store at 4 blocks every 3 minutes that would mean that she took 6 minutes (4+4 = 8) to get back home. Using this data we can create the following equation model to calculate the total time of the trip.

T = 8 + 5 + 6

which one of these tables shows a direct variation​

Answers

Answer:

The first one

Step-by-step explanation:

A direct variation is when x and y are multiplied or divided by the same number. For example, in the first one y is always 8 times x. But, in the 2nd 3rd and 4th one that is not the case.

f(x) = x + 4 g(x) = 3x ^ 2 - 7 Find (fg)(x) .

Answers

Answer:

Step-by-step explanation:

(fg)(x) )

[tex](x+4)*(3x^{2} -7)[/tex]=[tex]3x^{3} -7x+12x^{2} -28[/tex] = [tex]3x^{3} +12x^{2} -7x-28[/tex]

Composite functions are functions that are gotten from combining multiple functions.

The value of the composite function (f o g)(x) is 3x^2 -3.

The functions are given as:

[tex]f(x) = x + 4[/tex]

[tex]g(x) = 3x^2 - 7[/tex]

To calculate the composite function (f o g)(x), we make use of:

[tex](f\ o\ g)(x) = f(g(x))[/tex]

We have:

[tex]f(x) = x + 4[/tex]

Substitute g(x) for x

[tex]f(g(x)) = g(x) + 4[/tex]

Substitute [tex]g(x) = 3x^2 - 7[/tex]

[tex]f(g(x)) = 3x^2 - 7 + 4[/tex]

[tex]f(g(x)) = 3x^2 -3[/tex]

Recall that:

[tex](f\ o\ g)(x) = f(g(x))[/tex]

So, we have:

[tex](f\ o\ g)(x) = 3x^2 -3[/tex]

Hence, the value of the composite function (f o g)(x) is 3x^2 -3.

A Sandra and Ben used gasoline at the same rate because - 15
B Sandra and Ben used gasoline at different rates because Ben drove a longer distance.
C Sandra and Ben used gasoline at the same rate of 12 miles per gallon.
Sandra and Ben used gasoline at different rates because Sandra used less gasoline.

Answers

Answer:

It is A

Step-by-step explanation:

6 x 15 = 90

9 x 15 = 135

Answer: A

Step-by-step explanation:

because the rate Sandra is using gas is 90/6 which is 15 and the rate Ben is using gas is 135/9 which is also 15. Since they are USING the gas, it is minus 15 (-15).
