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}

{t|<t<3}

Step-by-step explanation:

The domain of the relation represented by the graph is the time from 0 to 3 seconds the range of the relation is the heights from 0 to 64 feet.

1st on it correct

Step-by-step explanation:

Just answered it on Edge and got 100

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
