Answer:
C = 9x +2280
Step-by-step explanation:
The 2-point form of the equation for a line can be a place to start.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
C = (4800 -3000)/(280 -80)(x -80) +3000 . . . . . use given values
C = 1800/200(x -80) +3000 . . . . simplify some
C = 9x -720 +3000 . . . . eliminate parentheses
C = 9x +2280
Answer:
BC is 10 units.
Step-by-step explanation:
Given that,
AB=12 units
AD=33 units
AE=18 units
From the figure, AD=AE+ED ⇒ 33=18+ED ⇒ ED=15 units
⇒
⇒
Hence, BC is 10 units.
100% - (39% + 23%) = 100% - 62% = 38% <== the percentage of ppl in the water
