Question

Which of the following is a subset of the set
A: {integers divisible by 2 from 2 to 20}

anonymous · Answer

There are no choices :) I believe that there is supposed to be?

anonymous · Answer

{24, 26, 28}

 {4, 6, 8, 10}

 {integers divisible by 4 from 2 to 40}

 {0, 2, 4, 6 …}

anonymous · Answer

Well, it could technically be either C or D, but I am not quite sure which one it is...

anonymous · Answer

I wish I could help more.

jim_thompson5910 · Answer

It's not C because this set includes numbers that go over 20

and it's not D because this set also has numbers that go over 20 (and it goes on forever whereas the given set does not)

cwrw238 · Answer

its definitely not A as the elements are all over 20

If h(x) = −3x − 10, find h(−3).

jim_thompson5910 · Answer

Replace x with -3 and evaluate

h(x) = -3x-10

h(-3) = -3(-3)-10

jim_thompson5910 · Answer

Note: -3(-3) means "negative 3 times negative 3"

Make sure you follow PEMDAS correctly

jim_thompson5910 · Answer

what is -3 times -3?

anonymous · Answer

9

jim_thompson5910 · Answer

so 

h(-3) = -3(-3)-10

becomes

h(-3) = 9-10

Think of 9-10 as "you have $9 in your pocket and you buy something that is $10. Are you in debt? If not, how much do you have left? If you are in debt, how much are you in debt?"
