If x is squared, that will be biggest by the end because it gets bigger the quickest. x^2 + 4 is always 4 greater than x^2, no matter what the value of x is.

5x+3 is always 3 greater than 5x also.

Besides that, you can rank them based on their slopes (5x < 7x < 8x, etc.)

So,
5x
5x + 3
7x
8x + 3
x^2
x^2 + 4

You can also just say “eventually” means that they’re asking to find the values of each when x is really big. so just choose x=100, and plug that into each one.

So, to check that order:
5(100) = 500
5(100) + 3 = 503
7(100) = 700
8(100) + 3 = 803
(100)^2 = 10,000
(100)^2 + 4 = 10,004

Those are in ascending order, so that must be the right order!

If a gardener make $60 a day working and has to pay $15 for each day that he does not show up and he only works a total of 20 da

nydimaria [60]

Answer:

14 days

Step-by-step explanation:

Amount earned by gardener for each day worked = $60

Amount paid by gardener for each day when absent = $15

Total number of days = 20

Let the total number of days when the gardener was working = x

Then he was absent for (20 - x) days.

Total amount earned during this period = $750

Then, $\[60x - 15(20-x) = 750\]
$

=> $60x + 15x - 300 = 750$

=> \[75x = 1050\]

=> x = 14

So the gardener worked for 14 days out of 20.
