Solve the following equation. Express your answer as an integer, simplified fraction, or decimal rounded to two decimal places. −1=−2v+15

v=8

Step-by-step explanation:

in order to isolate the variable from the numbers, you add 2v to both sides. Then, you add 1 to both sides because you want to leave the numbers on one side, and the variables on the other. You then get 2v=16 and you divide both sides by 2 to get v by itself.

-1=-2v+15

+2v. +2v

-1+2v=15

+1. +1

2v=16

2v÷2=16÷2

v=8

their is no graph showing

step-by-step explanation:

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.
