If f(x) = 2x - 9, which of the following are correct? Select all that apply. f(-1) = -11 f(2) = 5 f(3) = -3 f(0) = -9 f(-3) = 15
Yuri [45]

f(-1) = -11 and f(3) = -3 . these functions are true .

What does a math function mean?

  • A relationship between a group of inputs and one output each is referred to as a function.
  •  A function is an association between inputs in which each input is connected to precisely one output.
  • A domain, codomain, or range exists for every function. f(x), where x is the input, is a common way to refer to a function.
  • In mathematics, a function is an expression, rule, or law that establishes the relationship between two variables (the dependent variable).

given function  f(x) = 2x - 9

   f(-1) = -11 ⇒ x = -1 put in function

                       f( -1 ) = 2 * -1 - 9  ⇒ - 11

    f(2) = 5   ⇒ x = 2 put in function

                    f( 2 ) = 2 * 5 - 9 = 1

    f(3) = -3  ⇒  x = 3 put in function

                     f ( 3 ) = 2 * 3 - 9 = -3

       f(-3) = 15   ⇒  x =  -3 put in function

                     f( -3) = 2 * -3 - 9 = - 15

Jorge’s printer can print 36 pages in 18 minutes. How many pages can it print in 1 hour
Sloan [31]

Answer:

120 pages can be printed in 1 hour.

Step-by-step explanation:

First divide 36 by 18 to figure out how many pages can be printed in a minute.

Like this: 36 pages ÷ 18 minutes = 2 pages in one minute.

Now, multiply 2 by 60 to figure out how many pages can be printed out in a hour.

Like this: 2 pages in one minute × 60 minutes ( one hour) = 120 pages in one hour can be printed.

Hope this helps!
