0.00024

Step-by-step explanation:

= 2.4 × 10-4

(scientific notation)

= 2.4e-4

(scientific e notation)

= 240 × 10-6

(engineering notation)

(millionth; prefix micro- (u))

= 0.00024

(real number)

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.
