24.75 feet was the initial height of the bird. We can use definitions and corresponding addition here:
The word descending is denoted as something or someone that moves or slopes downward. Our equation will look like so, with x representing the initial height of the bird:
x - 8.25 = 16.5 (or in other words, 16.50)
Now that we have our equation set up, we can use inverse operations to solve.
16.50 + 8.25 = 24.75
Since doing addition gave us a total of 24.75, we know that the initial height of the bird is 24.75 feet. To check our work, we can plug this number in for x:
24.75 - 8.25 = 16.50
When calculating, this equation is true. Therefore, the initial height of the bird is 24.75 feet. If you need extra help, do not hesitate to let me know and I will gladly assist you.

South west
Shifting 4 units left (decreasing in x-axis by 4 units)
Shifting 5 units down (decreasing in y-axis by 5 units)
Apply to every vertices coordinates(x - 4, y - 5)
New coordinates
A(-2, -1)
B(-1, -4)
C(1,0)
Answer:
4+3x
It's pretty straight forward, you have the number 4 that is added to the rest of the expression because sum is addition, and the product of 2 numbers is multiplication so it would make 3(x) or 3x, which results in 4+3x.
