If it's the average speed of [a,b] where a is less than b, both are on the x axis (time), and both are in the domain of x then the equation is(f(b)-f(a))/(b-a)where f(b) is the distance when time=b and f(a) is the distance when time=a(?)
b + 9 = 21 Take the + 9 across the other side of the equals sign. a plus becomes a minus. b = 21 - 9 so... b = 12. This can be checked by setting b to 12 in the first equation b + 9 = 21 12 + 9 = 21 which is correct.
All the time
12 = -4/2 * -2 + b 12 = -2 * -2 + b 12 = 4 + b 8 = b
The speed upstream is B - C where B is the speed of the badge in still water and C is speed of the current The speed downstream is B + C. Velocity = Distance/Time : therefore Time = Distance/Velocity. Time for upstream journey = 6/(B - C) Time for downstream journey = 6/(B + C) BUT Total time for journey = 2 = 6/(B - C) + 6/(B + C) = 12B/(B2 - C2) Therefore 2B2 - 2C2 = 12B : However, B = 8kph so substituting gives, 128 - 2C2 = 96 : 2C2 = 32 : C2 = 16 : C = 4 The speed of the current is 4kph.
A. a setting from any time in an imaginary place B. a setting from a difficult time with great conflict C. a setting from the current time in a real place D. a setting from a past time in a real place

how do you play a c on the recorder
To play "London Bridge is Falling Down" on the recorder, you must first familiarize yourself with the notes of the song and practice the fingerings on the recorder. Start by playing the notes one at a time, slowly building up the speed as you become more comfortable. Pay attention to the rhythm of the song and practice playing along with a metronome or a recording to help with timing.
its what one would call a B and B setting...
