After four weeks, they both have the same amount of money. Larissa’s amount of money is constantly decreasing and Chuco’s is constantly increasing. At the four week mark on the graph, their two line intersect, representing that at that point they had the same amount of money.
For this case we must resolve the following inequality:
Subtracting 7 from both sides of the inequality we have:
Dividing by 3 to both sides of the inequality we have:
We multiply by -1 on both sides, taking into account that the sense of inequality changes:
Thus, it is observed that to solve the inequality it is necessary to change the meaning of it.
ANswer:
False. It is necessary to change the sense of inequality
Answer – B. Stretch
Transformations are said to be rigid if they maintain the same size and shape, so by inference, a change in shape can only be accomplished by a non-rigid transformation. A form of non-rigid transformation is a stretch or compression therefore, in order to change the shape of a function, you need to stretch or compress it.
