Give your answer in interval notation. Let's solve this : x (x + 7.5) = 38.5 subtract 88.5 from both sides and simplify x^2 + 7.5x - 38.5 = 0 factor as (x - 3.5) ( x + 11) = 0 the solutions will come from one or more of these intervals : (-infinity, -11) , (-11, 3.5) or (3.5, infinity)

WebGraphing inequalities with variables. We can use a number line to show the possible solutions to an inequality. Example 1: x>4 x > 4. An inequality like x>4 x > 4 tells us that x x can be any value greater than 4 4. We can show this on a number line by putting an open circle on 4 4 and shading the numbers that are greater than 4 4. WebExample 2 Solve for x and check: - 3x = 12. Solution. Dividing each side by -3 ... The mathematical statement x . 3, read as "x is less than 3," indicates that the variable x can be any number less than (or to the left of) 3.
