Hello :
let :

calculate : x ......x <span>≠ -1
</span>





the inverse function is :

domain of : g is the range of : f
as an interval : ]-∞: 3 <span>[</span>U ]3;+∞[
Answer:
A positive times a negative will always be a negative and when u divide a positive by a negative the same rules apply so it will be a negative
The unknown digit is 7 because 6.471 is greater than 6.470 and less than 6.48.
The objective function is simply a function that is meant to be maximized. Because this function is multivariable, we know that with the applied constraints, the value that maximizes this function must be on the boundary of the domain described by these constraints. If you view the attached image, the grey section highlighted section is the area on the domain of the function which meets all defined constraints. (It is all of the inequalities plotted over one another). Your job would thus be to determine which value on the boundary maximizes the value of the objective function. In this case, since any contribution from y reduces the value of the objective function, you will want to make this value as low as possible, and make x as high as possible. Within the boundaries of the constraints, this thus maximizes the function at x = 5, y = 0.
Answer: An article was sold at a 20% discount, at Rs. 400. What was its marked price?
Let M denotes the required marked price of the given article.
Hence from above data we get following relation,
(1 - 20/100)*M = 400
or (4/5)*M = 400
or M = (5/4)*400 = 500 (Rs) [Ans]
