Answer:
see the explanation
Step-by-step explanation:
we have
closed circle on 2 to closed circle on 6
That means -----> All real numbers greater than or equal to 2 and less than or equal to 6
In interval notation is ------> [2,6]
In set builder notation is ----> { x ∈ R | x ≥ 2 and x ≤ 6 }
The sum will be x+y because their ages are variables.
Answer:
Step-by-step explanation:
Absolute Value. Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative. The absolute value of 2 + 7 is 5.
Has two solutions x = a and x = -a because both numbers are at the distance a from 0. ... An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.
