Step-by-step explanation:

Given : Working together,Edith and Rupert can pick 3 quarts of blueberries in an hour.

i.e. The number of quarts of blueberries they pick in one hour = 3

Then, the number of quarts they can pick in 7 hours is given by :-

Hence, the number of quarts they can pick in 7 hours is 21 quarts.

answer: 4

step-by-step explanation:

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.
