Given the functions f(x)=7-2x and g(x)=5x-3 find g(f(-4)) find f(g(x))
lara31 [8.8K]

Answer:

g(f(-4)) = -8

f(g(x)) = 13-10x

Step-by-step explanation:

g(f(-4)):

Plug in the equation f(x) into the variable x of g(x), we have:

(gof)= 5(7-2x)-3

Plug in x = -4 and the answer is -8

f(g(x)):
Plug in the equation g(x) into the variable x of f(x), we have:

7-2(5x-3) = 7-10x+6 = 13-10x

Service Department Charges and Activity Bases
gladu [14]

The answers to the question are:

  • 50
  • 75
  • 10
  • 14

<h3>a. How to determine the service charge rate for the month of October</h3>

This is the number of calls for the help desk

160000/3200 = 50per call

network center

735000/9800

= 75 per device that was monitored

Electronic mail

100000/10000 =

10 for the mail account

For smart phone support

124600/8900

= 14 per phone extension

<h3>b. Charges to the COMM sector </h3>

for helpdesk

5200 * 0.25 * 0.96 *1.5 calls * $50

= 93600

For network center

(5200 * 0.25 * 0.96) + 600] x 75

= 138600

For Electronic mail

5200 * 0.25 * 0.96 * 10 per email account

= 12480

Smart support charge

5200 * 0.25 * 14 = 18200
