Answer:

Distance=3.1 miles

Step-by-step explanation:

Step 1: Determine how many meters make a mile

The conversion rate expression is;

1 mile=1.60934 kilometers

Step 2: Convert 5 km to miles

Using the expression below;

Distance in miles=distance in kilometers/1.60934

where;

distance in kilometers=5 km

replacing;

Distance in miles=5/1.60934

Distance in miles=3.10686 miles

Step 3: Round off to nearest tenth of a mile

Nearest tenth of a mile=1/10=0.1 , the same as rounding of to the nearest 1 decimal place

Distance 3.10686 miles rounded off to 1 decimal place=3.1 miles

Distance=3.1 miles

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
