PLEASE HELP! HISTOGRAM AND FREQUENCIES!!

In the diagram, the ratio of ab to ae is (1/2) . what is the ratio of the length of to the length of ?

Given the graphed function below which of the following orders pairs are found on the inverse function

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
