The truck contained 100 lovaes of bread, and the food was about to be distributed evenly when the village chieftain suddenly stopped proceedings. "the elders of the village have decided that each child will recieve half a loaf of bread, each woman two loaves of bread and each mand three," bellowed the chieftain/ " But we may not have enough bread in those proportions," argued a relief worker. :You have 100 loaves?' asked the chieftain.

At this time of year we note certain larvae forming a cocoon (I hope I am using the correct term) against window frames, sills, grill covers, etc. Recently I have noted a speckled brown and grey spider about 2 cm from leg to leg with its fangs imbedded in the cocoon. Anyone here with an opinion on what the predator and prey are?

ok so the question is
y=-2|3(x+4)|+5
so i know that it is a verticle compression of 2 and a horizontal stretch by 1/3
the normal step pattern is over 1 up 1 over 1 up 1
so does that mean i multiply all over 1s by 1/3 and divide all up 1s by 2?
