when x is an integer, what is the solution set of 5≤x <8? a: {5,6,7,8} b:{5,6,7} c: {6,7,8} d: {6,7}
Well let me help you out with a and you can figure out the rest
ok ;) @swissgirl
Firstly lets look at the notation \( 5 \leq x \leq 8\) This translates to X is less than 8 and greater than or equal to 5
So what can x equal?
What values can x take on? X can equal anything less than 8 or greater than 5 including 5 So x={5,6,7}
Do you follow so far?
yeah, i see what your saying :) @swissgirl
Now a: The set is {5,6,7,8} The question is asking us what values from this set can x be
So what wld ur guess be?
so x = {5,6,7,8} ???
@swissgirl
Can x=8? What did we say in the beggining?
Whoops ;/ lol anything less than 8 and greater than 5 @swissgirl
So what elements in this set equals x?
We scratched 8 But can x equal 5,6 and 7?
hold on.....yes ;) I found out the answer.. i think it is {5,6,7} @swissgirl
Yessssssss
Now lets go on to b The set contains {5,6,7} so what is eh solution set for x?
the integers that satisfy these conditions are 5,6,7 @swissgirl
Yesssss but we would right it as a set x={5,6,7}
How abt the set {6,7,8}?
Its ok :) I got it..... Thank you sooooooo much @swissgirl
Ok GREAT :)
Thank you sooo much @swissgirl
