Use the Pythagorean theorem a+b+c

|a|² = |b|² + |c|²

Step-by-step explanation:

the pythagoras theorem states that in a right angled triangle, the square of the sum of the hypotheneus side is equal to the sum of squares of the opposite side and adjacent side.

That is,

| HYPOTHENEUS|² = |OPPOSTITE|²  + | ADJACENT|²

inorder to use the pythagorean theorem to evaluate this

|a|² = |b|² + |c|²

answer: i believe its b. if you sound out the sentences that sounds wrong.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
