I don't understand your question.
The value of given expression when x=-4 and y=4 is 1250.
The expression is missing in the question which is
.
We have to solve it for x= -4 and y = 4.
Now putting the value of x and y we get,



Hence the value of given expression when x=-4 and y=4 is 1250.

Answer:
B, 7/20
Step-by-step explanation:
If two events are mutually exclusive that means that there is no intersection
so in the union formula: AUB=A+B-A∩B
A∩B=0
we can write P(a)=x
7/10=7/20+x+0
7/10-7/20=x
x=7/20
A line segment has two endpoints and a ray has one endpoint....
so it is a line segment.
