Answer:
78.5
Step-by-step explanation:
x3.14 (pie)
so then substitute.
5x5=25
25x3.14=78.5
1 is A - just plug and chug
2 is B - for 2 linear equations to have infinite solutions they mustbe the same
3 is C
4 is C - that is where they intersect
5 is A - same slope and different intercepts means no solutions
Answer:
114,250
Step-by-step explanation:
Enid invested 43,750
Eddie invested 92,000
the difference is 114,250
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
