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:
True
Step-by-step explanation:
Givens:
From if part: m<CEF+m<DCF=90
From picture: m<CEF+m<FEG=90
Subtracting the equations we get:
m<DCF-m<FEG=0
Adding m<FEG on both sides:
m<DCF=m<FEG
So true.
The middle one has an error.
