Answer:
x > 1
Step-by-step explanation:
5 - 2x < 7
-5 - 5
-2x < 2
/-2 /-2
(dividing by negative switches the sign)
x >- 1
I think the answer is an auction!
a function can't have one input mapped to multiple outputs. this is the case for where 4 maps to -2 and 2, so remove (4, -2)
Graph a.
3x+2y=12
-3x -3x
2y=-3x+12
2/2y=(3x+12)/2
y=-1.5x+6
graph b.
4x-y=5
+y +y
4x=y+5
-5 -5
4x-5=y
c) 11 units is the difference between y-coordinates of graph a and y-coordinates of graph b.
e) at (6,-3) x=6 cuts into graph a
