9. In a 500m race, Alice beat Bridget by 50m and Bridget beat Connie by 50m. By how many metres did Alice beat Connie? Assume that each person runs at a constant speed.
(A) 50 (B) 90 (C) 95 (D) 99 (E) 100

40 minutes

step-by-step explanation:

add the time and multiply by 2

answer: 12

step-by-step explanation:

because yes

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.

for future students the answer is b

hope i
