Let's solve this problem graphically. Here we have the following equation:

So we can rewrite this as:

So the solution to the equation is the x-value at which the functions f and g intersect. In other words:

Using graphing calculator, we get that this value occurs at:

Answer:
March is the first month
Step-by-step explanation:
If we make a graph. We can see that the quantity of sold water skis overpasses the quantity of snow skis in the month of March.
Answer:
The graph is positive and decreasing for all real values of x where x < -1
Step-by-step explanation:
we have

The function is a vertical parabola open up
The roots (x-intercepts) are x=3 and x=-1
The vertex is the point (1,-4 ) is a minimum
using a graphing tool
see the attached figure
we know that
In the interval (-∞,-1) ---> the function is positive and decreasing
In the interval (-1,1) ---> the function is negative and decreasing
In the interval (1,3) ---> the function is negative and increasing
In the interval (3,∞) ---> the function is positive and increasing
therefore
The graph is positive and decreasing for all real values of x where x < -1
Answer:
64%
Step-by-step explanationI added total and points earned and divided 66/102 and I got 0.64. I moved my decimal 2 places to the right and got 64%
-150 points cause 200-350= -150
