Answer:

The whale is at a depth 120 feet below the sea level.

Step-by-step explanation:

A grey whale is cruising at a depth of 233 feet below sea level. The depth below the sea level has the negative position, thus the initial position of the whale is -233.

It rises 73 feet, the position of the whale becomes 73 feet higher. This means we should add 73.

Then it comes up another 40 feet, so we need to add 40.

Mathematically,

-233+73+40=-160+40=-120

The whale is at a depth 120 feet below the sea level.

Every year Ethan earns 38,428. Each year he spends 21,728 on expenses. How much money should he have left over?
PolarNik [594]

Answer:

16,700

Step-by-step explanation:

Given that,

Earning of Ethan = 38,428

Ethan spends 21,728 on expenses.

We need to find the amount of money he has left over. It can be calculated as follows :

Left money = Earning - Spent

= 38,428 - 21,728

= 16,700

So, he has left over 16,700.

Will mark brainlist please help!!!!
MArishka [77]

Answer:

f(-3)= -8

f(2) = 4

Step-by-step explanation:

The first equation x ≤ 0 means that if the variable x, or in our case, -3, is less than or equal to 0, the answer will be calculated into the equation.

3(-3) + 1 = -8

The bottom equation x ≥ 2 means that if the variable, x, or in our case, 2 is more than or equal to 2, the answer is 4. Since 2 is equal to 2, the answer would then be 4.
