Using the functions f(x) = 2x + 7, g(x) = x2 - 4, and h(x) = 5x. Find all of the following. Make sure your answer is in simplest
Stolb23 [73]

Answer:

Given

f(x) = 2x+7

g(x) = x^2-4

h(x) = 5x

a. 4h(x)

= 4 * 5x

= 20x

b. f(x) - g(x)

f(x) - g(x) = 2x + 7 - (x^2 - 4)

= 2x+7-x^2+4

=-x^2+2x+7+4

=-x^2+2x+11

c. f(g(x)) = 2(g(x))+7

=2(x^2-4) +7

=2x^2-8+7

=2x^2-1

d. g(x)h(x) = (x^2-4)(5x)

= 5x^3 - 20x

e. g(x) / f(x) = x2 - 4/ 2x + 7

Answer: It would take 9 hours for 4 painters to paint 720 feet of fence.

Step-by-step explanation:

1.) Calculate the time needed to paint the 720 ft fence with 2 painters.

    a.) Divide 720 by 280 to get how many times greater 720 is than 280.

         720 / 280 ≈ 2.57

    b.) Multiply the time needed to paint the 280 ft fence with 2 painters by 2.57.

         7 * 2.57 ≈ 18

2.) Calculate the time needed to paint the 720 ft fence with 4 painters.

   a.) Assuming that each painter paints the same amount of fence, divide the time in half, as 4 painters is double the original amount, so it would take half of the time.

       18 / 2 = 9

First tour is 4 child tickets and 8 adult tickets for 128 dollars second tour is 6 adult tickets for 72 dollars what is the pric
V125BC [204]

Answer:the price of one child ticket is $8

the price of one adult ticket is $12

Step-by-step explanation:

Let x represent the price of one child ticket.

Let y represent the price of one adult ticket.

First tour is 4 child tickets and 8 adult tickets for 128 dollars. This means that

4x + 8y = 128 - - - - - - - - - - 1

Second tour is 6 adult tickets for 72 dollars. This means that

6y = 72

y = 72/6 = $12

Substituting y = 12 into equation 1, it becomes

4x + 8 × 12= 128

4x + 96 = 128

4x = 128 - 96

4x = 32

x = 32/4 = $8
