The # of taxi accidents is approximated by y = -143.3x^2 + 1823.3x + 6820 and the # of injuries is approximated by y = -416.72x^

spin [16.1K]

To analyze the problem first is to arrange the equations according to their uses:
# of taxi accident y = -143.3X^2+1823.3x+6820
# of injuries y = -416.72X^2+4416.7x+8500
So the answer if X = 9 will be represented by 1999
# of taxi accident y = 11622.4
# of injuries y = 14495.98
