For #12, they are vertical angles so 4x=84 degrees. Therefore you take 84 and decide by 4 and you get what x is (it’s 21)
Answer:
C) Solution set of{x|X<-3} n {xl x> 5) is an the empty set.
Step-by-step explanation:
Here, the solution set is given as : set of {x| x < -3 } ∩ {x l x > 5)
Now, defining the each set , we get
{x| x < -3 } = ( .... -6,-5,-4 ,-3) = P
and the SET {x l x > 5} = (5,6,7,........ ) = Q
Now, by taking the intersection of two sets,we get
P ∩ Q = NULL SET as they don not have any element in common.
⇒ {x| x < -3 } ∩ {x l x > 5} is an empty set
Hence, solution set of{x|X<-3} n {xl x> 5) is an the empty set.
<u>Answer:</u>
6x-5y=-10
<u>Step-by-step explanation:</u>
We are given an equation in words and we are to translate it and then re-write its standard form:
<em>'y space equals space 6 over 5 x space plus space 2
'</em>
Re-arranging this given equation to get:
So the correct answer option is 6x-5y=-10.
Answer:
-49
Step-by-step explanation:
First you convert them in improper fraction then it comes
35/3 × -21/5
With the help of cross multiplication we get
7×-7
And then 7×-7 = -49
