Given:

To find:
The equation that can be simplified to find the inverse of given equation.
Solution:
We have,

To find the inverse first we have to interchange x and y.

Now, we to solve this equation for y to find the inverse.
So, the equation
can be simplified to find the inverse of given equation.
Therefore, the correct option is 4.
0 is the answer ofr 1/3m -1-1/2n when m=21 and n=12
Area of triangle is
A=b•h/2
A=(10x+5)(2x-5)/2
A=20x^2-50x+10x-25/2
A=20x^2-40x-25/2
A=2(10x^2-20x-12.5)/2
cancel 2 in numerator and denominator
A=10x^2-20x-12.5 in^2
Hope this helps
The answer is between Day 3 and Day 4. If you look at the slope of the line between Day 3 and Day 4, you can see that it's horizontal, whereas the other slopes are very steep. Therefore, the answer is between Day 3 and Day 4.
