Rajah di bawah terdiri daripada tiga buah segi tiga empat sama yang sama saiz dan sebuah sukuan bulatan. diberi perimeter seluruh rajah itu ialah 53cm. Hitung
a)jejari sukuan bulatan itu

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.
