Which of the following is an example of why irrational numbers are not closed under addition?
startroot 4 endroot + startroot 4 endroot = 2 + 2 = 4, and 4 is not irrational
one-half + one-half = 1, and 1 is not irrational
startroot 10 endroot + (negative startroot 10 endroot) = 0, and 0 is not irrational
–3 + 3 = 0, and 0 is not irrational

the answer is c

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

what graph
