Answer:
y² = 4 - \frac{4x^2}{25}

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
\frac{25y^2}{25}  =  \frac{100-4x^2}{25}

y² = \frac{x100-4x^2}{25}

y² = \frac{100}{25} - \frac{4x^2}{25}

y² = 4 - \frac{4x^2}{25}

Hope this helps :)

s2008m [1.1K]

Answer:

150(1-x)

Step-by-step explanation:

120(1-x)

Then it is increased by 25%

How could you answer this question?
erastova [34]

Answer:

1000 times

Step-by-step explanation:

because the tenths place would mean the 2 is equal to 0.2

and the 100s place would mean 200

to get to 200 from 0.2 you multiply by 1000, because the decimal point moves to the left for each zero.
