Answer: -1
Step-by-step explanation:
If k is equal to negative one then we can input it into it for the exponent and solve.
If multiplying exponents and they have the same base then you will just add the exponents and let the exponents stay the same.
The exponents are -3,1, and -1 add them.
-3 + 1 - 1 = -3
The base is 10 so we will raise 10 to the negative 3rd power.
Let l, t, b represent the numbers of lions, tigers, bears, respectively.
2l +3t +3b = 156 . . . . . . . 156 meals per day are supplied
l +t = 3b . . . . . . . . . . . . . . there are 3 times as many great cats as bears
l +t +b = 68 . . . . . . . . . . . there are a total of 68 animals
_____
The last 2 equations tell you
.. 4b = 68
.. b = 17
Subtracting 3 times the last equation from the first gives
.. -l = -48
There are 48 lions, 3 tigers, and 17 bears.

First you differentiate it. So:
x^3 + 2x - 1 = 3x^2 + 2
at point (2, 1) the x value is 2 so you substitute that into the differentiated equation.
you get 3(2)^2 + 2 = 14
Because Jon is walking at a constant rate, the equation will be simple division. Because Jon walks 3 miles per hour, if you divide 12 miles by 3 miles per hour (12 mi / 3 mph), the miles in the equation cancel and you are left with 12 / 3 hours. 12 / 3 = 4, so Jon is hiking for 4 hours.
