Trevor is analyzing a circle, y2 + x2 = 49, and a linear function g(x). Will they intersect?
2 answers:
We have a circumference that is given by the following equation:
We can write this equation in its standard form as follows:
On the other hand, the linear function is given as the following table:
To check if the circle and the line intersects, let's substitute the equation of the line into the equation of the circle to see if there is a real solution, so:
Finally the intersects are:

Answer:
Step-by-step explanation:
We essentially need to solve for l; in other words, we must isolate it to one side.
First, notice that the term doesn't have any l terms in it, so we can just move this to the left side by subtracting both sides by
:
A - = 2lw
Now, the right side has 2lw, so we must divide both sides by 2w to isolate l:
