The lines represented by the equations 2y + 4x = 4 and y +2x = -4 are the same line, neither parallel nor perpendicular, perpendicular or parallel?

answer: 48

just remember to use pemdas:

parentheses

expressions

multiplication

division

addition

subtraction

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

answer: x=3 and y=4
