Answer:
x = ± 
Step-by-step explanation:
Given
y = x² + 7 ( subtract 7 from both sides )
y - 7 = x² ( take the square root of both sides, thus
x = ±
Answer:
{x,y} = {-2,2}
Step-by-step explanation:
Solve equation [2] for the variable y
7y = 7x + 28
y = x + 4
Plug this in for variable y in equation [1]
-8x + 4•(x +4) = 24
-4x = 8
Solve equation [1] for the variable x
4x = - 8
x = - 2
By now we know this much :
x = -2
y = x+4
Use the x value to solve for y
y = (-2)+4 = 2
Solution :
{x,y} = {-2,2}
and this intersects at only one point so your answer is A
Answer:
<u>Colinear points</u>: Points that lie on the same line.
<u>Coplanar points</u>: Points that lie in the same plane.
<u>Plane</u>: a flat, 2D surface with no height.
1. Three colinear points: A, B, E
2. Four coplanar points: A, B, C, E
3. A plane containing E: plane S
4. Two points and a line that lie in Plane T: Points F & G, Line L
5. Two planes that contain l: S and T
