A printing machine can print 12 magazines in 2.5 minutes. Which graph has a slope that best represents the number of magazines per minute the machine can print?

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

47 - 90 = 43

43 - 180 = x

x = 137
