Describe in words a sequence of transformations that maps ∆abc to ∆a'b'c' transformation #1 transformation # write an ordered-pair rule for each transformation in the sequence: transformation #1 transformation #2

Step-by-step explanation:

There are many ways the figure could be transformed to get from one to the other. The orientation of both figures is ABC is CCW, so if reflection is used, an even number of reflections are needed. The direction of AB is "east" and the direction of A'B' is "north", so we know the transformations have to result in a rotation 90° counterclockwise.

Quick and Easy

Since point A is at the origin, rotation 90° CCW about the origin leaves point A where it is, and aligns the AB segment on the y-axis. From there, the translation up and left is easy to see.

Other Alternatives

There are other transformations that could be used, including rotation about (-3, 1). This latter transformation could do the whole thing in one step. (Your problem requires 2 steps, so this is not a suitable answer.)

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
