y= 1/2x +2
if x=0 y=2 (0,2)
if x=2 y = 1/2 *2 +2 =1+2 =3 (2,3)
you now have two points so you can plot the line
The answer is 5
Because if x = 2 then you just do 2+3 which is 5
So for this there is going to be two equations; One showing how much they earned total and one showing how much more Garth made.
Let x mean how much Sandi made and y mean how much Garth made.
The first equation is going to be

The second equation is going to be

.
I'll be using the substitution method since that is already set up for it. So in the first equation substitute y for x+25 since the second equation tells us that is the equivalent to y.
And your equation should look like this:

. From here you can solve for x.
Combine like terms to get

Subtract 25 on each side to get

Divide 2 on each side to get

Now that we had got what Sandi had earned, we can substitute x for 200 in either equation to solve for y. I'll be solving for y in the second equation.

To sum it up, Sandi earned $200 and Garth earned $225.
112
suplementry angle add to 180 so 180_68=112
