C is the best choice in my opinion
Implicit expression refers to equation that are not strictly expressed in terms of y and x separately. In this case, the derivative of expression
<span>sqrt(xy)=x^2y+1 is
sqrt x * 0.5 y ^-0.5 dy + </span>sqrt y<span> * 0.5 x ^-0.5 dx= x^2 dy + 2xy dx
dy (x^2 - 0.5 (</span>x/y) ^0.5) = dx (2xy - 0.5 (y<span>/x)^0.5)
dy/dx = </span>(2xy - 0.5 (y/x)^0.5) / (x^2 - 0.5 (<span>x/y) ^0.5)</span>
Answer:

Step-by-step explanation:
Area = L x W
5/9 = 2/3 * W
5/9 ÷ 2/3 = W
5/6 = W
No, it's one or the other.
Answer:
1. always
2.never
3.sometimes
4.always
5.sometimes
6.always
Step-by-step explanation:
It is clear from the given number line, that
is a negative integer and
is a positive integer.
1. It is always true because addition is always commutative property.
2. It is never positive because product of two different sign is always negative.
3.dividing two integer with unlike sign may result in any integer
4.when a positive quantity is reduced from a negative quantity, the result is always negative.
5.division of two unlike integers may result the same,if they both have the same value
6.If an opposite of a positive integer is added to that positive integer itself, the result is is always 0.
