Answer:
Step-by-step explanation:
It may not tell you anything. You have to be careful how you think about the answer to this. An ordered pair is just that: it describes an x and y value and that is really all that it does.
However it may also be used to describe the solution to a system of equations which cross in one place. For example, if you plot
y = x + 1
y = -3x + 2
The ordered pair that gives the point where both equations equal the same thing is (0.25,1.25) The graph is shown below, and the ordered pair marks the solution.
Solution:
In Parallelogram B CDE
BC= DE, BC ║DE
CD = BE , CD ║BE
Also, ∠B=∠D and ∠C=∠E →→In a parallelogram opposite sides are equal and parallel, as well as opposite angles are equal.Diagonals Bisect each other.
∠B= 60° , ∠C ED= 40°
CE is a transversal and BC║DE.
∠CED=∠BCE = 40° →→Alternate interior angles
In Δ BCE
∠B + ∠BCE + ∠BEC= 180°→→→Angle sum property of Triangle.
60° + 40° + ∠ B E C= 180°
100° + ∠BEC=180°
∠BEC= 180° -100°
∠BEC= 80°
Answer:
18%
Step-by-step explanation:
=
----> cross multiply
504(100) = 2800x
50400 = 2800x
=
18 = x
