Solve the system of equations below.
y=3x
2x + y = 15

If f(x)=x^3 and g(x)=2x+7 when g(x)=-5

100 points, hi, i’m not sure how to get the equation from the graph and table.

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
