Question

Dominick is training for a race. He spends 0.75 hours running each time he runs and 1.5 hours swimming each time he swims. This week, he spent more than 6 hours training for the race. Which graph represents his possible training times this week? Image for option 1 Image for option 2 Image for option 3 Image for option 4

Answer 1

The Answer Is A

Step-by-step explanation

For this case we define the variables:

X: Number of times Dominick runs per week

Y: Number of times that Dominick swims per week

If you spend more than 6h training per week, we have an inequality of the form

0.75x + 1.5y > 6

The set of inequality is given by the shaded region of the graph

Answer 2

The answer is "A"!

Explanation:

0.75x + 1.5y> 6
