# 1 solve the system of elimination. if he system is inconsistent or has dependent equations, say so

x - 4y = - 4

-4 -3y= - 3

#2. Jill is 17.5 kilometers away from joe. both begin to walk toward each other at the same time. Kill walks at 2 kilometers per hour. they meet in 5 hours. how fast is Joe walking?

#3 In a chemistry class, 9 liters of a 4% silver oxide solution must be mixed with 10% solution to get a 6% solution. How many liters of the 10% solution are needed?

#4 divide

42x⁴-36x³+12x²

6x³

#5 decide whether the pair of lines is parallel. perpendicular, or neither

3x - 8y = - 9 and 32x + 12y = 14
