I am having difficulties solving this problem someone pls help.
igor_vitrenko [27]

Answer:

Each time, the x is being multiplied by -3 to result in the output.

So for every x input, multiply by -3.

For the y output for 15, you would divide by -3 to find the input x

For example, when 7 is the input, multiply by -3, and the output y would result in -21.

Answer:

BD does bisect the angle created by ABC, however it does not bisect segment AC. So it really depends on what you are determining the bisection to be.

Step-by-step explanation:

We can tell that it is bisecting the angle since it creates two congruent angles.

We can tell that it does not bisect the segment as AD and CD are not the same length.
