The table below represents the total number of laps jessica swam in the pool this summer:
week laps
1 18
2 28
3 38
4 48

if the linear function representing the number of laps jessica swam each week is f(w) = 10w + 8, what does the 10 represent in this function?

the number of laps jessica swam in week 0
the week of the summer that jessica swam
the number of laps jessica swam in total
the number of laps jessica increased her swim by each week

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
