Answer:

Step-by-step explanation:

Step 1:

Age of grace = x

Age of her son = y

Step 2:

   x > 20

x + y ≥ 60

Step 3:

    x +y ≥ 60

        y ≥ -x +60            

Step 4

(45, 22)

x > 20              ;     y  ≥ -x + 60

45 > 20           ;    22  ≥   -45 + 60

                            22  ≥ 15

The graph that best represent the relationship between time and cost is option A as it is a proportional graph

<h3>How to know the graph that represent the relationship between time and number of team?</h3>

Each week 6 teams register to participate.

Therefore, for every week 6 team register to participate in the competition.

This simply implies as time increases , the number of participant in the competition also increase.

Therefore, the equation that can be use to represent this situation is as follows:

y = 6x

where

  • y = number of team registered
  • x = time in weeks.

Hence,  the graph that best represent the relationship between time and cost is option A as it is a proportional graph. The registered team increases as the time in weeks increase.
