The answer to that is -24a - 6
Answer:
or (1,1)
Step-by-step explanation:
You can apply the Method of substitution.
Knowing that
(second equation), you can substitute it into the first equation and solve for the variable y:

Now you need to substitute
into the second equation
to calculate the value of the variable x. Then:

Then, the solution is:
or (1,1)
Answer:
2.9
Step-by-step explanation:
11.6 divided by 4 equals 2.9
Answer: Four-thirdsπ(6)³
Step-by-step explanation: The formula for the volume of a sphere is attached in the image down below.
Notice that two of the options listed have <em>three-fourths</em> but we use <em>four-thirds </em>to find the volume of a sphere. This means that we can eliminate the 1st and the 3rd option.
Now, we will multiply that by π and then by the radius cubed which is also written as 6³. This means that our answer would be the second option.
Answer:
This may not be entirely satisfied proof but you should get the idea.
Proof: Start with 1 = -1.
Then we know that if a= b then a + c = b + c and also a / c = b / c.
So we can add 1 to both sides.
We have 1 + 1 = -1 + 1 ⇒ 2 = 0.
Now divide both sides by 2 and we would have 1 = 0.
Now add both sides by 1. This yields 2 = 1.
Therefore if 1 = -1 then 2 = 1.
