After college you start a job earning $40000 a year. You get a 6% raise each year. a) How much will you earn in year 2?
Elodia [21]
The answer to Part a is $44,800. I did this by 40000*2*3/50 which comes out to 4,800 you add that to your beginning worth, 40,000. Part b is as follows; 9,600 which comes out to be $49,600. Replace the 2 in the original equation to be 40,000*4*3/50. The number '2' and '4' represent the years, and the 3/50 is equal to 6%. 6% in math terms is 3/50. The answer to part c is as follows; 40000*10*3/50 which comes out to be 24,000 so your final answer for part c is: $64,000 I hope this helped! Let me know if you need more work shown, and I'll add more! :)

Plz help me with this

Your answer would be the second option, (-4,5).

We can find this by substituting in each point into the equation y < |x - 3| and seeing if it is true.

For the first one you get 1 < |2 - 1|. |2 - 1| = |-1| = 1, and 1 cannot be less than itself, so this is false.

For the second one you get 5 < |-4 - 3|. |-4 - 3| = |-7| = 7, and 5 is indeed less than 7, so this is correct.

I hope this helps!
