Answer:
A=-4 B=-8 C=8
Step-by-step explanation:
If you need to check these answers multiply the answer by the second number.
A) -4x-3=12 A negative times a negative is always positive.
B)-8x9=-72 A negative times a positive is a negative.
C) 8x-2=-16 A negative times a positive is a negative.

Answer:
Step-by-step explanation:
it has no solutions b/c the lines are parallel...but at a different offset.. so they never cross
For T = 89.5 degrees C:
E(t) = 1100(90 - 89.5) + 520(90 - 89.5)^2= 1100(0.5) + 520(0.5)^2= 550 + 130= 680 m
For T = 90 degrees C:
E(t) = 1100(90 - 90) + 520(90 - 90)^2= 0 + 0= 0 m (meaning that boiling point is 90 degrees C at ground level)
