Si: \qquad JT = 5x + 8JT=5x+8J, T, equals, 5, x, plus, 8,
\qquad CT = 70CT=70C, T, equals, 70, y
\qquad CJ = 7x + 2CJ=7x+2C, J, equals, 7, x, plus, 2,
Encuentra JTJTJ, T.

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.
