Need help #1. The answer is shown, but I don’t know how to get to the answer. Please teach and show steps.
Rufina [12.5K]

Answer:

B

Step-by-step explanation:

We are given that <em>x</em> and <em>y</em> are functions of time <em>t</em> such that <em>x</em> and <em>y</em> is a constant. So, we can write the following equation:

x(t)+y(t)=k,\text{ where $k$ is some constant}

The rate of change of <em>x</em> and the rate of change of <em>y</em> with respect to time <em>t</em> is simply dx/dt and dy/dt, respectively. So, we will differentiate both sides with respect to <em>t: </em>

<em />\displaystyle \frac{d}{dt}\Big[x(t)+y(t)\Big]=\frac{d}{dt}[k]<em />

Remember that the derivative of a constant is always 0. Therefore:

\displaystyle \frac{dx}{dt}+\frac{dy}{dt}=0

And by subtracting dy/dt from both sides, we acquire:

\displaystyle \frac{dx}{dt}=-\frac{dy}{dt}

Hence, our answer is B.

If 7m = 35, then 7m + 4 = 35 + 4<br> NAME THE PROPERTY
Reptile [31]

The property that is applied in 7m+4=35+4 is addition property of equality

Given :

If \; 7m=35, then \; 7m+4=35+4

From the above equation we can see that 4 is added at the both sides of the equation .

we can add same number at the both sides of the equation to balance the equation . That is called as addition property of equality

Here , 4 is added on both sides of the equality to balance the equation .

So , addition property of equality is applied .
