Step-by-step explanation:
Answer:
(3.5, 4)
Step-by-step explanation:
add and then divide (x1+x2 / 2, y1 + y2 / 2) so [(1+6)/2, (3+5)/2], so (3.5, 4)
Answer:
x(x − 6) (x + 5)
Step-by-step explanation:
this is the factored form of x^3 - x^2 - 30x
hope this helps and is right :)
Answer:
\\x= P/(c -d)[/tex],
Assume that the price of each minute in the first plan is $c and that the second plan charges a flat rate of $P and a charge of additional $d for every minute.
Step-by-step explanation
Assume that the price of each minute in the first plan is $c and that the second plan charges a flat rate of $P and a charge of additional $d for every minute.
Thus, the monthly cost of a customer who consumes x minutes in each plan is:
For the first plan: 
and for the second plan: 
Considering that the monthly costs must be the same in each plan, you have to:
![cx = P + dx\\ transposing terms\\cx - dx = P\\ applying common factor\\(c -d)x = P\\ dividing by [tex]c - d](https://tex.z-dn.net/?f=cx%20%3D%20P%20%2B%20dx%5C%5C%20transposing%20terms%3C%2Fp%3E%3Cp%3E%5C%5Ccx%20-%20dx%20%3D%20P%5C%5C%20%20%20applying%20common%20factor%3C%2Fp%3E%3Cp%3E%5C%5C%28c%20-d%29x%20%3D%20P%5C%5C%20dividing%20by%20%5Btex%5Dc%20-%20d)
\\x= P/(c -d)[/tex].
For example if
, Then the number of minutes would be,
and the total cost for each plan would be
