#9 the sum of two angles is 90 degrees, creating a right angle.
#10 the sum of the two angles is 180 because the form a supplementary angle
Answer:
perpendicular
Step-by-step explanation:
2-x =3y
3y = 2-x
y = -1/3x+2/3
slope is -1/3
2y +10 = 6x
2y = 6x -10
y = 3 -5
slope is 3
-1/3 and 3 are negative reciprocals so the lines are perpendicular.
Answer is
D
Step-by-step explanation:
-4xm=-4m
-4x+5= -20
Answer: 6k+19
Step-by-step explanation:
To combine like terms subtract the k term from the 7k term.
7k-k+19 = 6k+19
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:

The standard form of the parabola:
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.
