Answer:
(-15, 13)
Step-by-step explanation:
-3(8x + 9y = -3)
4( 6x + 7y = 1)
-24x - 27y = 9
24x + 28y = 4 (add both equations)
y = 13
6x + 7*13= 1
6x + 91= 1
6x = 1 -91
x = -91/6
x = -15
<span>A parabola that has a horizontal directrix is a parabola that opens up or down.
Here are some of its components:
1) Standard equation of a parabola with a horizontal directrix: (x-h)^2 = 4a(y-k),
a = distance from vertex to focus
2) Vertex at (h,k)
3) Focus(h,k+a)
4) Directrix: y = k-a
5) Axis of symmetry: x = h
A parabola that has a vertical directrix opens to the right or left and is on its side.
Here are some components
1) Standard equation of a parabola with a vertical directrix: (y-k)^2 = 4a(x-h)
2) vertex (h,k)
3) focus (h+a,k)
4) directrix: x = h-a
5) Axis of symmetry: y = k

The striped wall and the floor intersect at a 90 degrees angle since they are perpendicular.
<h3>What is an
angle?</h3>
An angle is formed when two or more lines intersect at a point. Types of angles are<em> acute, obtuse, and right angled</em>.
Two lines are said to be perpendicular if there is a 90 degrees angle between them.
