Ax-bx+y=z which of the following represents the formula that could be used to find x?

Step by step explanation:

You first subtract z on both sides of the equal sign

ax-bx=(z-y)

Since a and b both have a "x" you can subtract them

(a-b)x=(z-y)

then you divide "x" on both sides of the equal sign

a is the right answer

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.
