Answer: a=3 & b=-2
Step-by-step explanation:
40 x 5280 = 211200 feet per hour
211200 / 3600 = 58.666 = 59 feet per second
-3+6k+11k-10-9y+5x-y-13x
-13+17k-10y-8x
-5x+6x-9x+5xy
-8x+5xy
the fees in 1997 was $3088
fees in 2000 was $3292
average rate of increase= (3292-3088)/(2000-1997) = 204/3=68
so average rate of increase is $68 per year
