The height of a triangle is 55.5 feet, and the base of the triangle measures 34.4 feet. Find the length, to the nearest tenth of a foot, of one of the two congruent legs of the triangle.

y = x + 95

y = 42 + 95

y=137 mm hg

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.
