Answer:
This system has no solution:
y = x²
y = 0 · x - 1
Step-by-step explanation:
Hi there!
I propose these two equations:
y = x²
y = 0 · x - 1
This system has no solution because in the quadratic function "y" is always positive for every value of "x", while in the linear function "y" is always -1 for every value of "x". Then, there will not be a pair (x,y) shared by both functions.
In other words, there is no value of "x" that satisfies this expression:
x² = 0 · x - 1
In the attached graphic, you can see that both curves never touch (in red is the quadratic function and in blue is the linear function), hence, the system has no solution.
Have a nice day!
<u>ANSWER</u>
See attachment for the graph
<u>EXPLANATION</u>
The standard equation of the vertical ellipse with center at the origin is given by
where
The ellipse has its vertices at (0,±17).
This implies that:a=±17 or a²=289
The foci are located at (0,±15).
This implies that:c=±15 or c²=225
We use the following relation to find the value of b²
We substitute into the formula for the standard equation to get:
