Find the expression to represent how much you would expect a cub to weigh $d$ days after it's born as exponential growth function $y=a\cdot b^d,$ where $a$ is the initial panda's weight and $b$ is the rate of growth.

A newborn red panda weighs 100 grams, then $a=100.$

A healthy cub gains about 7% of its newborn weight per day, then

$b=1+0.07=1.07$

Hence,

$y=100\cdot (1.07)^d$

Find the answer to the algebra equation: 18xy - 27y

Im assuming you are supposed to factor this problem considering there is no = sign. starting with numbers, you can factor, or divide, both of those numbers by 9. moving on to letters, both terms have a “y” attached to them, so you can take out a y as well. leaving you with the simplified equation being

9y (2x-3)
