Suppose when the price of hybrid automobiles rises, consumers buy fewer hybrid automobiles. this implies that a. there is a negative relationship between hybrid automobile prices and quantities purchased by consumers. b.there is a direct relationship between hybrid automobile prices and quantities purchased by consumers. c.there is a positive relationship between hybrid automobile prices and quantities purchased by consumers. d. there is a oneminus−tominus−one relationship between hybrid automobile prices and quantities purchased by consumers.

Suppose when the price of hybrid automobiles​ rises, consumers buy fewer hybrid automobiles. this implies that  "there is a negative relationship between hybrid automobile prices and quantities purchased by consumers" (A).

A negative relationship implies that there is a backwards connection between two variables- when one variable reductions, alternate increments. The other way around is a negative connection as well, in which one variable increments and alternate decreases.

whats the

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
