Answer:
18 feet
Step-by-step explanation:
The difference in elevations is ...
-12 -(-30) = -12 +30 = 30 -12 = 18 . . . feet
The ray is 18 feet above the whale.
8x⁵ + 4x² - 12
All numbers are divisible by 4, so we put 4 on the outside of the parenthesis.
So, when doing that, all you have to do is divide everything by 4.
4(2x⁵ + x² - 3)
So, your answer is the first answer choice.

Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4 , then
y = - 4x + c ← is the partial equation
To find c substitute (- 2, - 5) into the partial equation
- 5 = 8 + c ⇒ c = - 5 - 8 = - 13
y = - 4x - 13 → B
