Answer:
= 6.
Step-by-step explanation:
We are given that n(A) = 4, n(B) = 5, and
= 3.
And we have to find the value of
.
<u>As we know that the union formula is given by;</u>
Now, substituting the values given in the question in the above formula, we get;


Hence, the value of
= 6.
Answer:
x = 0
Step-by-step explanation:
The axis of the symmetry has the same x coordinate of the vertex
V (x) = -b/2a
in both equations b is equal to 0 and a 0/a number different from 0 gives always 0 as a result
Answer:
x¹=-6 x²=0
Step-by-step explanation:
Substitute y =0
Swap sides
Factor expression
Split into possible cases

Answer:
Option B
Step-by-step explanation:
Don't trust answers teachers don't bother to spell correctly. Plus, finding the 100th term is very easy.
However, the explicit formula will take a long time to use, because it's explicit.
Option C is just wrong. You're supposed to multiply in the recursive formula.
Option D might be correct, but never trust those answers. Teachers do that to trip you up
Answer:
(-(23/3), -(11/3))
Step-by-step explanation:
x=y-4
2x-5y=3
=====
2x-5y=3
2(y-4)-5y=3 [Substitute (y-4) for x in the 2nd equation]
2y - 8 -5y = 3
-3y = 11
y = -(11/3)
y = -3 2/3
Use this in the 1st equation to find x:
x=y-4
x=-(11/3)-4
x = -(11/3)-(12/3)
x = -(23/3)
x = -7 2/3
