Answer:
undefined
Step-by-step explanation:
Becouse any number under a root sign that is negative does not give any answer.Therefore it doesn't exist in real number system.
I'm not so sure but i think it's D hope it's right
Answer: 4
Step-by-step explanation: To have an equation with no solution you have to get something like 0=1 meaning you have to remove all the variables. In this equation you would distribute to get xy+2y+2x=2x+12+4x where y is the missing number. then combining like terms you get xy+2x+2y=6x+12. Subtracting 2x from both sides you get xy+2y=4x+12. Now to get the variables gone y has to be 4 so that the variables to cancel out. By plugging in 4 you can see this works; 4x+8=4x+12 and by subtracting 4x from both sides you get 8=12 which is not true meaning there is no solution.
You are given <span>the system y > 2x and y < 2x. if the system of inequalities changes in sign convention, that is, y < 2x, It would mean that any value of x multiplied by two will always be greater than y.</span>
