Jason is selling video games. to earn his monthly bonus, he must sell a minimum of 5 games. he has 30 he can sell. the video games cost $20 each. the function f(x) = 20x can be used to represent this situation. what is the practical range of the function? question 16 options: 1. all whole numbers from 5 to 30, inclusive. 2. all whole numbers from 100 to 600, inclusive. 3. all real numbers. 4. all multiples of 20 between 100 and 600, inclusive.

Correct choice is B

Step-by-step explanation:

The function represents the situation, where x is the number of sold video games and f(x) is the total cost of sold games.

Jason  must sell a minimum of 5 games, this means that  He has 30 video games he can sell, then . Thus, the domain of the function is

The range of the function f(x) is

21

jk it's 20

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
