Five swimmers are entered into a competition. four of the swimmers have had their turns. their scores are 9.8 s, 9.75 s, 9.79 s, and 9.81 s. what score must the last swimmer get in order to win the competition?

24

step-by-step explanation:

answer: 1 + 1 = 11

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

maya’s expression will generate the wrong sum because she violated the commutative property.
