To find the X intercept, make Y equal to 0. To find the Y intercept, make X equal to 0.
5x - 2(0) = 20
5x = 20
x = 4
5(0) - 2y = 20
-2y = 20
y = -10
Lisa is measuring the depth of a well. She drops a ball from a height of h feet into the well and measures how long it takes the ball to hit the bottom of the well.
Polynomial =
where 0 is the initial speed and h is height it was dropped .
Now find depth of the well, when t = 3.5 seconds and h = 6 ft
=
=
= -196 + 6
= -190
So depth of the well is 190 feet (negative sign represents the depth, below the ground)

It's important to have an order of operations because without it then you could solve the math equation however you want. For example, using order of operations: 5+6×4=29, without using order of operations: 5+6×4=44. Without the order
operations you could solve the math equation however you want. If there was no order then there would never be a correct answer to the equation.
