Use a triple integral to find the volume of the given solid. The tetrahedron enclosed by the coordinate planes and the plane 8x+y+z= 4.

Volume = cubic units

Step-by-step explanation: Given the equation find the limits:

For z:

8x + y + z = 4

z = 4 - 8x - y

limits 0 < z < 4-8x-y

For y:

4 - 8x - y = 0

y = 4 - 8x

limits: 0 < y < 4-8x

For x:

4 - 8x = 0

x = 1/2

limits: 0 < x < 1/2

Calculating triple integral and determining volume:

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
