Evaluate f(-12) given f(x) = -21x - 12
frozen [14]

Answer:

The answer for the given function is f( -12 ) = 240.

Step-by-step explanation:

Given:

f(x)=-21x-12

To Find :

F ( -12 ) = ?

Solution:

Function:

  1. A function is like a machine that gives an output for a given input.
  2. A function has an independent variable which is called the input of the function.
  3. The output for a given input is called the dependent variable.

For Example

f ( x ) = x + 3

x = independent variable

f ( x ) = Output for a given input

Here we have

f(x)=-21x-12\\Put\ x=-21\\\therefore f(-12) = -21\times -12 - 12\\\therefore f(-12) = 252 - 12\\\therefore f(-12) = 240

Therefore f(-12) = 240

Carlos didn't earn enough for the last apartment he was looking at, so he is still searching. He found one that costs $625 per m
tresset_1 [31]

Answer:

$1875

Step-by-step explanation:

Given the information:

  • An apartment costs: $625 per month
  • They require that the cost of rent be no greater that a third of his monthly income
  • The must earn at least 3 times the cost of his rent

=> the smallest amount of money that Carlos needs to make per month to be approved to move in:

= 3 times of $625

= 3*$625

= $1875

because 625  is exactly 1/3 of $1875

Hope it will find you well.
