2x + 5y = -8 . . . (1)
-133x - 4y = -8 . . . (2)
(1) * 4 => 8x + 20y = -32 . . . (3)
(2) * -5 => -665x + 20y = 32 . . . (4)
(3) - (4) => 673x = 0
x = 0
From (1), 2(0) + 5y = -8
5y = -8
y = -8/5
Divide 8 by 9
8 / 9 = 0.888
0.88 is greater than 0.60 so it is not between 0.45 - 0.60
Answer: an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
Step-by-step explanation:
Imagine two planes: they can be parallel or not. If they are parallel, then they don't have common points, but your planes have common points P and Q.
So, you can conclude that these two planes are not parallel, then they should intersect. Two planes intersect <span>in a straight line and this line consists of all common points of both planes.
</span>
If planes are named BPQ (points B, P, Q do not lie on one straight line) and CPQ (points C, P, Q do not lie on one straight line), you can see two common points P and Q. Hence the intersection line must contain these two points and may be named as PQ (and points B and C do not lie on this line).
Answer: correct choice is C.
