8 (Maryland, Michigan, Montana, Missouri, Massachusetts, Mississippi, Minnesota, and Maine)
systems of inequalities can only be solved ______
graphically
4x - 9y = 2
12x - 5y = -38
(-4,-2)
2x - 3y = -2
y= -4x + 24
(5,4)
y = 1/2x + 2
y = 1/4x + 4
(8,6)
What does the acronym “nvm” stand for?
What is nevermind
How is graphing systems of inequalities different than graphing systems of equations?
they use dotted lines sometimes and you have to shade to find the solution
5x + 2y = 48
3x + 2y = 32
x=8
x + y = 10
-y = 5 + x
no solution
4x - 5y = 15
8x + 5y = 45
