Leon throws a ball off a cliff. The graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds. What is the domain?

{t| 0 ≤ t ≤ 3}
{t| 0 ≤ t ≤ 48}
{t| 0 ≤ t ≤ 64}
{t| all real numbers}Which portrays inadequate data?

The equation 8x-2-5x+7=x has one solution.we start by combining like terms: 8x-5x-2+7=x3x-2+7=x3x+5=xcancel the variable to the right of the equals sign by subtracting: 3x+5-x=x-x2x+5=0subtract 5 from both sides: 2x+5-5=0-52x=-5divide both sides by 2: 2x/2 = -5/2x = -2.5
