Answer:
-5/7
Step-by-step explanation:
-3 3/7 + 2 5/7
-3 - 3/7 + 2 + 5/7
-3 + 2 + 5/7 - 3/7
-1 + 2/7
-5/7
I think the correct answer should be 1/8 or 1:8
Answer:
B
Step-by-step explanation:
I had this on my previous test, lol
Step-by-step explanation:
To do Order of Operations, we need to go with the order of the formula, PEMDAS.
P= Parenthesis
E= Exponents
M= Multiply (Whatever Comes First in Equation: M and D)
D= Divide
A= Addition (Whatever Comes First in Equation: A and S)
S= Subtraction
---------------------------------------------
So, we need to start with parenthesis, there aren't any, so we move on to Exponents.
There are no Exponents either, so we start with division, then multiplication.
(We always have to go left to right).
So,
-9 - 6 + <u>8 / -4</u> x -2
-9 - 6 + <u>-2 x -2</u>
-9 - 6 + 4
Our problem is:
-9 - 6 + 4
We do subtraction, then addition. (Left to Right)
<u>-9 - 6 </u>+ 4
<u>-15 + 4</u>
-11.
Therefore, the answer is -11.
(Corrected)
Let's take the derivative of each term one by 1
x^2
Apply the power rule for derivatives.
2x^(2-1) = 2x
You get 2x.
2x
Apply the power rule (x^1) and the constant multiple rule.
2 * x^(1-1) = 2 * x^0 = 2
You get 2.
-4
The derivative of a constant is 0.
Put that together and you get 2x + 2
Have an awesome day! :)
