The first one would be the right one!
you just take all the y one side and the numbers on one side
so 8y+4= 6+3y
now 8y-3y= 6-4
therefore 5y = 2

It depends on what you mean by the delimiting carats "^"...
Since you use parentheses appropriately in the answer choices, I'm going to go out on a limb here and assume something like "^x^" stands for
.
In that case, you want to find the antiderivative,
Complete the square in the denominator:
Now substitute
, so that
. Then
which simplifies to
Now, recall that
. But we want the substitution we made to be reversible, so that
which implies that
. (This is the range of the inverse sine function.)
Under these conditions, we have
, which lets us reduce
. Finally,
and back-substituting to get this in terms of
yields
Answer:
0.236
Step-by-step explanation:
First put it in order
0.199, 0.211, 0.225, 0.236, 0.257, 0.264, and 0.283
Then find the middle number
0.236
Answer:
-233/40
Step-by-step explanation:
5/8 + 1/4 - 2(3/4 + 13/5)
5/8 + 2/8 - 6/4 + 26/5
7/8 - 30/20 + 104/20
7/8 - 134/20
35/40 - 268/40
-233/40
Answer: 31
How: If there are two negative signs like this, you would connect them together and make it into a addition sign where you then can add them.
