Answer:
Answer is 81y^4z^4
Step-by-step explanation:
The expression is (-3yz) (-3yz) (-3yz) (-3yz).
Since all the four terms have power 1:
(-3yz)^1 (-3yz)^1 (-3yz)^1 (-3yz)^1
We know that we can add the powers if the terms have same base
So,
=(-3yz)^1+1+1+1
=(-3yz)^4
=(-3)^4(y)^4(z)^4.
If the power is an even number than the negative sign changes into positive sign.
=3^4y^4z^4
=81y^4z^4
Thus the answer is 81y^4z^4....
Answer:
34
first of all use formula:
n(AUB)=n(A)+n(B)-n(AnB)
We can't match events with probability if there is no events... do you have the events?
Answer:
B
Step-by-step explanation:
Since the slope is going down the slope is negative and since 50 is positive when 0 its positive.
Also to find slope you do y/x
25/100=1/4 and since its a decreasing pattern the slope is -1/4
