Answer:
P(x) = -0.4 + 100
- 300
+ 500
Step-by-step explanation:
C(x) = 600 + 300
R(x) = -0.4 + 700
- 600
+ 500
P(x) = R(x) - C(x)
(-0.4 + 700
- 600
+ 500) - (600
+ 300
)
= -0.4 + 100
- 300
+ 500
This should be the answer.
Answer:
a. t
b. a (or x = a)
c. r
d.
1) c
2) t
3) a
4) p
Step-by-step explanation:
a. Draw vertical line passing through the point (c,0). This line intersects the graph at point L. Point L has coordinates (c,t), so
b. If draw the horizontal line passing through the point (0,p). This line intersects the graph at point K with coordinates (a,p), so
c. Note that then
d. Coordinates of point L are (c,t), coordinates of point K are (a,p)
