Answer:
Step-by-step explanation:
x²+y²=25
it is a circle with radius=5
x²-y²=3
it is a hyperbola.
x²-y²=3
so they intersect in four points.
If a binomial x-a is a factor of a polynomial p(x), then p(a)=0.
x+2 is a factor of p(x)=x³-6x²+kx+10, so p(-2)=0.
Answer:
The third one (parabola)
Step-by-step explanation:
Do a vertical line test.
Basically draw vertical lines over the function. If the x-value has more than one y-value then it is a relation and not a function
Answer:
N/A
p-by-step explanation:
x minus 1 is already a simplified expression (can only be solved if you know x)
