The given lines are
x = 1 + t
y = 2t
z = -3t
The plane is x + y - z = 3
If the lines intersect the plane at a point p, then the lines should satisfy the equation of the plane.
That is,
(1 + t) + (2t) - (-3t) = 3
1 + t + 2t + 3t = 3
1 + 6t = 3
6t = 2
t = 1/3
Therefore the coordinates of the point p are
x = 1 + 1/3 = 4/3
y = 2(1/3) = 2/3
z = -3(1/3) = -1
That is p (4/3, 2/3, -1)
Answer: The point p has coordinates (4/3, 2/3, -1)
Plan A = 9 +0.17x
Plan B = 21 +0.12x
9+0.17x = 21+0.12x
X=240
9+0.17(240)=49.8
21+0.12 (240)=49.8
240 minutes and cost $49.80 each
Answer:
uh... yeah it's best to keep it in simplest form unless if it was involving graphs.
Answer:
98
Step-by-step explanation:
238-140=98 so 98 dollars been added.
Answer:
No it is not equivalent.
Step-by-step explanation:
5h + 2h² = 7h? 
5h + 2h² = 9h 
Because in the equation 5h + 2h² = 7h the 2h² was not calculated yet.
