the graph is incorrect, he shouldve shaded to the right, hope this helps
Answer: 2) Plant C is producing at a cost greater than the goal.
<u>it is the first one</u>, because y CAN be 1-3x, so the line is solid. then, it is a simple matter of placing it correctly based on the y-intercept, which is one. the shading goes under the line because it is <u>less than </u>or equal to
S+(2+1/2)s+20=48
2/2s+5/2s=48-20
7/2s=28
7s=28*2=2(20+8)=40+16
7s=56
s=56/7
s=8
Y >/= -1/2x + 2
Y > 2x - 3
You get the >, <, and = by looking at the shading and line.
A dotted line is just > or <.
A solid line is >/= or </=.
You get the y-intercept, or the +2 or -3 by looking at the point on the y-axis.
