Evaluate if x = 4.
f(x) = = - 3x + 8

Answers

Given that,

f(x) = -3x + 8

To find,

The value of f(x) at x = 4.

Solution,

We have,

f(x) = -3x + 8

We need to find the value of f(x) at x = 4

Pu x = 4 in f(x).

f(4) = -3(4) + 8

= -12 +8

= -4

So, f(4) is equal to -4.

?
PLEASE HELP ASAP

Answers

Answer:

20%

Step-by-step explanation:

So, I would set this up as a proportion-

72          x

90        100

Cross multiply-

100 x 72 = 7200

Divide-

7200/90 = 80

Subtract-

100 - 80 = 20

So, it is a 20% decrease

Alex is a stockbroker. Earns ​% commission each week. Last​ week, sold ​$ worth of stocks. How much did he make last week in​ commission? If he averages that same amount each​ week, how much did he make in commission in​ 2011?
