Think about all of the ways in which a circle and a parabola can intersect.
xeze [42]

There will be four ways a circle and a parabola can intersect because the solution of the quartic equation will be 4.

<h3>What is a circle?</h3>

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have a circle and a parabola:

As we know the standard form of a circle:

\rm (x-h)^2 +(y-k)^2=r^2

The standard form of the parabola:

\rm y = a(x-h)^2+k  

If we plug the value of y from the parabola equation in the circle equation, we get a quartic equation(4th order equation)

The solution of the quartic equation will be 4.

Thus, there will be four ways a circle and a parabola can intersect because the solution of the quartic equation will be 4.

Simplify the rational expressions. State any excluded values. Show your work. (3x - 6)/(x - 2)
cluponka [151]
Hello,

Put the 3 as a common factor.

Look:

3x - 6 = 3 . ( x - 2 )

Then,

( 3x - 6) / (x - 2) = 3 .( x - 2) / (x -2)

Now simplity ( x -2)

= 3

15x+5y=30 with y by itself​
SCORPION-xisa [38]

Answer:

15 x 1 + 5 x 3 = 30

Step-by-step explanation:

If you turn the x into a one then it multiplies 15 by one and then it remains at 15, then you multiply 5 and 3 so that's 15 and then 15 + 15 is 30.
