3. The sum of x and y is 9. The value of y is two more than the value of x. Write a system of equations to model this. fa+y=9
x = y + 2
x - y = 9
y + 2
x-y-9
x = y + 2
X +y=9
y = x + 2

x + y = 9

y = x + 2

Step-by-step explanation:

We need to write a system of equations to represent the given situation . The statements are ,

Statement 1:- The sum of x and y is 9.

Mathematically , we can write it as ,

Statement 2:- The value of y is two more than the value of x.

This simply means that y equals to 2 + x , that is

Therefore the system of equations will be ,

answer: plz give a pic and answer choices so i can answer!

step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
