40:28 is equivalent to 10:7
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! :)
To find the absolute value remove abt negative sign in front of a number and to think of all numbers as a positive
Answer:
90
Step-by-step explanation:
Answer:
no solutions
Step-by-step explanation:
Since the two terms have the same base, we are able to use the rule for subtracting logarithms:
Therefore, the equation can be written as:
By using the definition of a logarithm we can say that:
When plugging this solution in, you find that the term 
has x-6 evaluate to a number less than 0. This is not included in the domain of log functions, so 
is not a valid solution. This means that there are no solutions.
