x=-6+2y
x=2+2y
by subtraction
___________________________
x=-8
Substitute x by one of the two equations :
x=-6+2y
-8=-6+2y
2y=-8+6
2y=-2
y=-2/2
y=-1
I think this is the answer
I hope I helped you^_^
The answer to this is: x = y / 2
Answer:
2/ 5
Step-by-step explanation:
From the venn diagram, find tbe probability ;
P(work | sport)
Recall :
P(A | B) = P(A n B) / P(B)
From the venn diagram :
P(work | sport) = P(work n sport) / P(sport)
P(work n sport ) = 4
P(sport) = 6 + 4 = 10
Therefore,
P(work | sport) = P(work n sport) / P(sport)
P(work | sport) = 4 / 10
P(work | sport) = 2/5
Answer:
Step-by-step explanation:
120 is going to be 45 + x.
120 - 45 = x
120 - 45 = 75.
Answer:
-3.25 >-2.5 +r
Option 4 is right.
Step-by-step explanation:
Given picture is a graph of number line representing the area to the left of -0.75 not including -0.75
i.e. the graph shows r<-0.75, where r is a variable
Subtract 2.5 to both the sides
we get
-2.5+r <-0.75-2.5
or -2.5+r <-3.25
Or -3.25 >-2.5 +r
Option 4 is right.
Why other options are wrong:
i) 3.25<r+2.5. 0 satisfies this inequality but not included in the graph. Hence wrong.
ii)3.25>2.5+r
r=0 satisiffes this contradicting the graph again.
Thus second option is right.
iii) -3.25<-2.5+r
Here r =0 satisfies this equation contrary to graph. Hence option iii is wrong.
