Richard ran 13.7 km in the morning. After lunch, he continued running. When he finished the run, he
had covered 30.2 km in all. Write an equation that can be used to find how far Richard ran after lunch.
Let n be the distance in kilometers that Richard ran after lunch.

30.2 - 13.7=n

Step-by-step explanation:

To get how far he ran you have to subtract 30.2 from 13.7 therefore giving you  16.5 which will be the total distance he ran after lunch.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
