I want to believe the equation is,
f(x) = -5/x
This can be written as;
f(x) = y
y = -5 x⁻¹
derivative = dy/dx = (-1)(-5)x(⁻1-1)
= 5x⁻²
Derivative at x=11,
dy/dx = 5(11)⁻²
= 5/(11²)
= 5/121
So, the derivative of f(x) = -5/x at x=11 is 5/121.
Answer:
an hour....
Step-by-step explanation:
Answer: Charlie have to drive at a speed of 80miles per hour in order to reach there on time.
Step-by-step explanation:
At 4pm Charlie realizes he has half an hour to get to his grandmothers house for diner. Knowing that the time he has left is 30 minutes and the distance to his grandmother's place is 40 miles, the only thing that he can control is his speed
Speed = distance travelled / time taken
40/0.5 = 80 miles per hour
The graph first, and the graph fifth have no solution because there are no intersection options (A) and (E) are correct.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The graph of equations is shown in the graph.
As we know, if two equations of a function intersect on the coordinate plane that means they have a solution.
If there will be no intersection then the equations have no solution.
Thus, the graph first, and the graph fifth have no solution because there are no intersection options (A) and (E) are correct.

Answer:
B
Step-by-step explanation:
The entry A is the result of multiplying - x and 3x, that is
- x × 3x = - 3x² → B
