We are given with the expression <span>tan2x / x</span> and asked to evaluate the expression to limit as theta approaches zero. In this case, we substitute first zero. The answer is zero over zero. This is indeterminate so we derive the terms accdg to L'hopital's rule. The derivative is 2 sec^2 2x/1. cos 2x is 1 so is sec^2 2x. Hence the answer is 2.
Just do what you said (subsitute) and solve
x=number of classes
7.5x=5.5x+10
subtract 5.5x from both sides
2x=10
divide 2
x=5
5 classes
to find how much it costs, subsitute 5 for x in any equation
y=7.5(5)
y=37.5
total cost is $37.5 per month

24 • 24= 576 and 25 • 25= 625
76 • 76= 5,776 and 77 • 77= 5, 929
242 • 242= 58, 564 and 243 • 243= 59, 049√
766 • 766= 586, 756 and 767 • 767=588, 298
( by the way,
I'm squaring it because it's a square.)

3x -5≥ 5x-25
-3x. -3x
-----------------
---> -5 ≥2x -25
+25. +25
---------------------
---->20≥2x
20/2 ≥ 2x/2
----->10≥x, the greatest 'x' can be is 10.

why do you need do give almost ALL your points when people and your one only question???????????
