- 471 / 33 = 14.3 (rounded)
43= 2x-7 43+7=50 50/2=25 X=25
1- what you have to do is add then mulpity
2- you do the same thing then you get both anwers
Answer:
Equation the ellipse is
Step-by-step explanation:
In the question vertices of an ellipse are given as (1, 5) and (1, -5).Co vertex is (3, 0).
We know the standard form of ellipse is
If a > b then ellipse is horizontal
and the origin is (0, 0)
Given from the question a = 5 and b = 3
Since a > b therefore ellipse is horizontal
So the equation of ellipse will be
Therefore the answer is
Multiplying fractions is simple. You just multiply across so 7/3 x 2/3 is 14/9 and that is the simplest form.
