Step-by-step explanation:
y=1/2-5x
Answer:
0.00065104166
Step-by-step explanation:
Hello
y=3x-12
2x-3(3x-12)=-13
==>2x-9x+36=-13
==>-7x=-49
==>x=7
y=3*7-12
==>y=9
The standard equation of an ellipse is:
(x-h)²/a² + (y-k)²/b² = 1
Since the center at the origin, then h = k = 0
The height of this ellipse = 8 units and the width = 4 units, that means the major axis is b (=8) and the minor axis is a (=4)
Then the equation becomes:
x²/16 + y²/64 = 1
