Is it true w is the set of (s,w,n,t,c)
umka21 [38]

Answer:

{w} is the SUBSET of   {s,w,n,t,c}

Step-by-step explanation:

SUBSET: Any set  P is called a SUBSET of a set Q is ALL ELEMENTS of P are in the set Q.

i.e P ⊂ Q

Here, the given set  Q  =  {s,w,n,t,c}

Also, set P = {w}

Now,as the element w of set P is also an element of set Q.

⇒ P is the SUBSET of  Q

⇒ P ⊂ Q

⇒  {w} ⊂  {s,w,n,t,c}

Hence,   {w} is the SUBSET of   {s,w,n,t,c}.

Creating like bases 2to-3 and 16
AfilCa [17]

Answer:

  6

Step-by-step explanation:

Maybe you want a suitable common denominator for 2/3 and 1/6. If so, you can observe that 3 is a factor of 6, so 6 is a suitable common denominator.

  2/3 = (2/3)·(2/2) = (2·2)/(3·2) = 4/6

The equivalents, 4/6 and 1/6, share a common denominator of 6.

Which graph can be used to find the solution(s) to 4x=-4x?
Elden [556K]
<h2>Answer:</h2>

The graph is shown in the Figure below

<h2>Step-by-step explanation:</h2>

In this exercise, we have an equation. On the left side we have a straight line with slope m=4 and there is no any y-intercept. On the right side, on the other had, we also have a straight line, but the slope here is  m=-4. Therefore, by plotting these two straight lines, we have that the solution is the origin, that is, the point (0, 0).
