Are the given equations parallel,
perpendicular, or
neither?
y = 3x + 5
y = 3x - 7

Amuffin recipe, which yields 12 muffins, calls for cup of milk for every 1 cups of flour. the same recipe calls for cup of coconut for every cup of chopped apple. to yield a batch of 30 muffins, how much flour will be needed in the mix?

What does x = in this equation x+3+2x=x+5

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
