Answer is b . G)f(x))=9x^3+30x
Answer:
|x-3|+4 = 12
|x-3| = 12-4
|x-3| = 8
now solve for both positive and negative values
x - 3 = 8 | x - 3 = -8
x = 8 + 3 | x = - 8 + 3
x = 11 | x = -5
solution set : { 11, -5 }

Answer:
x=10, y=-1
Step-by-step explanation:
The coefficients of y are opposites, so the y-variable can be eliminated by adding the two equations.
... (x -y) +(2x +y) = (11) +(19)
... 3x = 30 . . . . . simplify
... x = 10 . . . . . . .divide by the coefficient of x
Use either equation to find y. We can use the first one, for example:
... 10 -y = 11
... -1 = y . . . . . add y-11
The solution is (x, y) = (10, -1).
