Which statement is true about 109?
a. it is a prime number.
b. it is a composite number.
c. it is a whole number that is neither prime nor composite.
d. it is not a whole 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.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
