Answer 4

2x + y < 10
2x - 4y > 8

Equation 1: 2x + y < 10 --> y < -2x+10
Equation 2: 2x - 4y > 8 --> y < 1/2 x -2
say that they are
y=-2x+10 and
y=1/2 x - 2

plug in x-values to get x-coordinates for each of those, (I mean graph just like any normal equation)
and in each, shade a part that i above the y in a dotted line (since it's not equal it's just more than)

after you shade each, the solution is going to be whatever is shaded in both equations/lines.

thx

Anytime!

Answer 7

so what about the ones that are on the line of the two? do those count too? @SolomonZelman
