I think the first photo, to find the answer, you have to add two sides together. If they are greater than the third, it’s a triangle. If not, then it’s not a triangle.

For A on the slide with 4 cards, the two angles labeled x are equal to each other. A triangle has 180 degrees. Subtract the given angle from 180 and divide by two.

I think those clues can Apple to most of the other pictures. That’s the most I can remember from my geometry class.

Use the differential equation given by dy/dx=xy/3, y>0<br><br> complete the table of values

melisa1 [442]

The $\dfrac{\mathrm dy}{\mathrm dx}$ row is filled by just plugging in the corresponding values of $x$ and $y$ into the ODE.

For example, when $x=-1$ and $y=1$ , you have

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{xy}3\implies\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{x=-1,y=1}=\dfrac{(-1)(1)}3=-\dfrac13$

and so on.

aniked [119]

Since you have the answers given, just track their walking.
After one hour, one guy has covered 3mi and the other 4mi, which is in total 7, not 14
After 2 hours, one guy has covered 6mi and the other 8mi, which is 14mi

The algebraic way would be:
3x +4x = 14 *x being the hour
7x = 14
x =2
