Given f(x) = 3x + 1, solve for x when f(x) = 7.
irakobra [83]

Answer:

f(7) = 22 or x =2

Step-by-step explanation:

  1. f(x) = 3x + 1
  2. f(7) = 3(7) + 1
  3. f(7) = 21 + 1
  4. f(7) = 22

<u>Or if the equation meant it like this:</u>

  1. f(x) = 3x + 1
  2. 7 = 3x + 1
  3. 6 = 3x
  4. 2 = x

can two different numbers have the same absolute value? if yes, give an example. if no, explain why not.
jekas [21]
Yes.  Absolute values are always positive, so for example:

the absolute value of 1 is 1, and the absolute value of -1 is also 1


or the absolute value of 7 is 7, and the absolute value of -7 is also 7

and so on!

A company sells doughnuts. They incur a fixed cost of $23000 for rent, insurance, and other expenses. It costs $0.1 to produce e
olasank [31]

Answer:

C(x) = 0.1x+23000

Step-by-step explanation:

Given that a company sells doughnuts. They incur a fixed cost of $23000 for rent, insurance, and other expenses. It costs $0.1 to produce each doughnut. The company sells each doughnut for $0.2.

Let X be the no of units produced

Then we have variable cost = 0.1x

Fixed cost = 23000 (irrespective of value of x)

Total cost

C(x) = 0.1x+23000

where C represents the total cost and x no of units produced.

Revenue function would be

R(x) = 0.2x assuming all doughnuts are sold.

Profit function would be

P(X) = 0.1x-23000
