Question

Hey can you please help me posted picture of question

Answer 1

Answer:
y² = 4 -
`(4x^2)/(25)`

Step-by-step explanation:
The given expression is:
4x² + 25y² = 100

We need to isolate the y².
This can be done as follows:
4x² + 25y² - 4x² = 100 - 4x²
25y² = 100 - 4x²

`(25y^2)/(25) = (100-4x^2)/(25)`

y² =
`(x100-4x^2)/(25)`

y² =
`(100)/(25) - (4x^2)/(25)`

y² = 4 -
`(4x^2)/(25)`

Hope this helps :)
