Barb and john each have a savings account with a sum of money in it. barb and john each begin to add a set amount of money each week. the graph shows the total amount in barb's account each week. select each correct answer. barb had more money in her account than john when they started their weekly savings. john is saving at a faster rate than barb. john saves $35 the first week. barb saves $15 each week.

John is saving at a faster rate than Barb.

John saves $35 the first week.

Barb saves $15 each week.

From the given graph, the rate of change of graph with points (0,15) and (5,90) will be

Hence, the amount added to Barb's account each week=$15

From the given table, the rate of change of graph with points (1,35) and (3,75) will be

Hence, the amount added to John's account each week=$20

Since, 20>15, thus John is saving at a faster rate than Barb.

The amount  in Barb's account in the beginning=$15

From table, John saves $35 the first week.

The amount  in John's account in the beginning=35-20=$15

Hence, they both have same amount in the beginning.

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.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
