If f(x) = square root of x + 12 and g(x) = 2 square root of x, what is the value of (f – g)(144)?

What is the percent of increase for a population that changed from 438,000 to 561,000

Solve the system by the elimination method. 3x - 2y - 7 = 0 5x + y - 3 = 0 to eliminate y, the lcm is 2. which of the following is the resulting equations? 1.3x - 2y - 7 = 0 5x + y - 3 = 0 2.3x - 2y - 7 = 0 -10x - 2y + 6 = 0 3.3x - 2y - 7 = 0 10x + 2y - 6 = 0

X+y=-4 x-y=2 use elimination with adding and subtraction
