Answer:

  a. (4, 26)

  b. The number of people jogging in 2004 was 26 million.

  c. 43 million

Step-by-step explanation:

To complete the ordered pair, use the given first value of the pair as the value of the variable in the equation. Evaluate the equation to find the second value of the ordered pair:

<h3>a.</h3>

  y = x +22

  y = 4 +22 = 26

The ordered pair is (4, 26).

__

<h3>b.</h3>

The ordered pair tells you (years after 2000, number of joggers in millions). That means the ordered pair (4, 26) tells you <em>4 years after 2000, there were 26 million joggers</em>.

__

<h3>c.</h3>

21 years after 2000, the value of x is 21, so the value of y is ...

  y = 21 +22 = 43

There will be 43 million joggers in 2021.

Evaluate 23x + 4y when x=20 and y=23
never [62]

Answer:

552

Step-by-step explanation:

23x + 4y when x=20 and y=23

if x=20 and y=23 all you have to do is replace the numbers and solve

23(20) + 4(23)

Multiply 23*20 which is equal to 460

Then you multiply 4*23 which is equal to 92

The problem is now 460 + 92

add it, and you get 552.

Hope this helps!!
