The actual length of c in the triangle shown is 15 cm. use the scale drawing of the triangle to find the actual length of side a, rounded to 2 decimal places. a) 0.15 cm b) 9.38 cm c) 11.72 d) 15.26 cm needs to be answered in at least 1 hour

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.

i think the answer is true
