Which expression represents triple the sum of y + 2? A.) 3(y + 2) B.) 5y C.) 3y +2 D.) 6

A. 3(y+2)

Step-by-step explanation:

B wouldn't work because it would be safe to assume that it represents the quintuple of the sum.  C also wouldn't work because although the y is tripled, the 2 isn't.  And D wouldn't work because it is only tripling 2.

A should be your answer since you are distributing the number 3 which is the same thing as a triple to get the sum of the answer which is 3y + 6.

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.

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
