Unfortunately, you cannot delete the question.
Step-by-step explanation:
Unfortunately, you cannot delete the question. Once a question or an answer has been submitted, you can only edit the question/answer for 30 minutes. Once this timeframe is over it can no longer be edited at all. This however does not include deleting the question/answer. The only possible way to delete a question is if it is flagged for whatever reason as going against the website's policy or by getting in contact with an administrator/moderator and having them remove the question.
B) {x|x ∈ U and 2x is prime}
x is greater than 1.
the only even prime number is 2
2 times anything is even.
the minimum x value is 2. 2x is 4, therefore higher than the only even number
every value 2x will have a multiple of 2 so it will not be prime.
Answer:
1st, 3rd and second last one
Any line can be expressed in the form y=mx+b where m is the slope and b is y intercept.
Two lines can either be parallel ,overlap or meet at one point .Let us look at different cases :
1)When two lines are parallel they do not intersect at any point and hence the system of equations have no solution.
2) When two lines overlap each other then the two lines touch each other at infinite number of points and we say the system of equations have infinite solutions.
3) When two lines intersect each other at one point we say the system of equation has one solution.
Part A:
The given lines are intersecting at one point so we have one solution.
Part B:
The point of intersection is the solution to the system of equations .In the graph the point of intersection of the lines is (4,4)
Solution is (4,4)
