To solve this problem you must apply the proccedure shown below:
1. You have that varies jointly as and and inversely as the product of and . Therefore, you can write the following equation, where is the constant of proportionality:
2. Now, you must solve for the constant of proportionality, as following:
3. Susbtiute values:
4. Substitute the value of the constant of proportionality into the equation:
The answer is:
Answer: (B) x^3
Explanation:
If you compare the graphs of
all on the interval -1 < x < 0, you'll find that y = x^3 is the smallest when x = -1
Squaring a negative number leads to a positive result, and similarly that happens with x^4 as well. This is because x^4 = (x^2)^2.
Plugging x = -1 into x^3 leads to y = -1 as a result.
I would be able to but i left my maths book at school and that has the explanation in, sorry :(
Answer:
g-13
Step-by-step explanation:
subtract 14g from 13 making it g and add 6+7
Hope this helps :P
