7x+8y=-18, 4x-9y=-3 solve the system of equations

Drag the tiles to the table. the tiles can be used more than once. nd g(x) = 2x + 5 model a similar situation. find the values of f(x) and g(x) let's say that the functions f(x for the given values of x. fix)=5(4) * g(x) = 2x+5

[15 points]find the least common multiple of the expressions: 1. 3x^2, 6x - 18 2. 5x, 5x(x +2) 3. x^2 - 9, x + 3 4. x^2 - 3x - 10, x + 2 explain if possible
