Answer:

Step-by-step explanation:
Let's start by finding the first derivative of
. We can do so by using the power rule for derivatives.
The power rule states that:
This means that if you are taking the derivative of a function with powers, you can bring the power down and multiply it with the coefficient, then reduce the power by 1.
Another rule that we need to note is that the derivative of a constant is 0.
Let's apply the power rule to the function f(x).
Bring the exponent down and multiply it with the coefficient. Then, reduce the power by 1.
Simplify the equation.
Now, this is only the first derivative of the function f(x). Let's find the second derivative by applying the power rule once again, but this time to the first derivative, f'(x).
Simplify the equation.
Therefore, this is the 2nd derivative of the function f(x).
We can say that: 
Lol another one?
So I looked at the graphs and the only one that actually even reaches 75 is the dotted one on the left. The one in the middle obviously doesn't go anywhere and the one on the right goes to 65, not 75.
Answer: d) 14
Step-by-step explanation:
Equation of a line passing through (a,b) and (c,d):

Equation of a line passing through (2, 18) and (–3, 8):

Comparing resulting equation
to
, we get value of b= 14.
Hence, correct option is d) 14
-7 - 7( 8x - 7 ) = -19 + 5x
⇔ -56x + 49 = -12 + 5x
⇔ -61x = -61
⇔ x = 1
Answer:
5/2
Step-by-step explanation:
In order to make the fractions equivalent, you need to place the whole number INTO the fraction itself. By doing so, your answer will be 5/2
Hope this helps :)
