Step-by-step explanation:

range = (3,7,1)  -  (9,6,7) \\  = ( - 6,1, - 6) \\ distance =  \sqrt{ {x}^{2} +  {y}^{2} +  {z}^{2}   }  \\  =  \sqrt{ {( - 6)}^{2} +  {1}^{2} +  {( - 6)}^{2}   }  \\  =  \sqrt{73}  \\  = 8.5 \: units

First, multiply the top equation by 2 and bottom by -3.
60x+60y=900
-60x-75y=-1035
————————
-15y=-135
—————-
-15=-15
y=9

So the answer should be 9.

Suppose xy=−4 and dy/dt=−3. Find dx/dt when x=−1.
user100 [1]
When x=-1: \quad (-1)y=-4\qquad\to\qquad y=4\)

Ok that gives us a little more information.
If we implicitly differentiate with respect to t, from the very start, then we can apply our product rule, ya?

x'y+xy'=0

The right side is zero, derivative of a constant is zero.
Where x' is dx/dt and y' is dy/dt.

From here, plug in all the stuff you know:
y' = -3
x = -1
y = 4

and solve for x'.

Hope that helps!

Always

Step-by-step explanation:

we know that

If points A, B, and C lie on a line, the the sum of the length of segment AB plus the length of the segment BC is always the length of segment AC

so

AC=AB+BC
