Ok this inequality tells you the number of devices you can have before the new plan costs more than the old plan. The new plan expression is $4.50x + $94m = y ( total cost). The old plan is $175m = y (total cost). You can see m (number of months) in both equations, you don't need it this time since we're going to to compare both to one month. Since they're both equal to y you can make them equal to each other. $4.50x + $94 = $175. Now you want to figure when the new plan is less than the old plan you switch the equal sign for a less than sign. $4.50x + $94 < $175; this will help you find the inequality you want. From there just use algebraic steps to find that x has to less than 18 or
x < 18.
(x-9)(x-3), because -9 and -3 make a sum of -12 and a product of +27
Hey there!
Median number :-
Given numbers are
2,1,3,5,3,1,4
Arranging in ascending order,
1,1,2,3,3,4,5
Median = 3
Hope this helps :)
