Which of the following are true about x? check all that apply.

We need to check where does x belongs in the sets.

Notice that x belongs to A and B. It's also belongs to both A and B but it doesn't belong to C. Now let's check each of the choices one by one to get the correct answer.

1) x \notin A is not correct because x belongs to A.

2)x\in B is correct.

3)x\notin C is also correct because x doesn't belong to C.

4) x \in A ∪ B is not correct because x belongs in both A and B.

5)x \in A∪C is not correct since x doesn't lie in C.

6)x\in A∩B is correct because x lie in both A and B.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
