Answer:

It landed at a height of 14 feet

Step-by-step explanation:

Given

y = -\frac{1}{8}x^2 +4x --- Path of a t-shirt

3y = 2x - 14 --- height of bleachers

Required

Height when t-shirts land in bleachers

3y = 2x - 14

Make y the subject

y = \frac{2}{3}x - \frac{14}{3}

Substitute y = \frac{2}{3}x - \frac{14}{3} in  y = -\frac{1}{8}x^2 +4x

\frac{2}{3}x - \frac{14}{3} =  -\frac{1}{8}x^2 +4x

Multiply through by 24

16x- 112 = -3x^2 +96x

Express as:

3x^2 + 16x  -96x- 112 = 0

3x^2 -80x- 112 = 0

Using a calculator:

x = 28 or x = -\frac{4}{3}

x can not be negative:

So:

x = 28

Substitute x = 28 in y = -\frac{1}{8}x^2 +4x to calculate the height it landed

y = -\frac{1}{8} * 28^2 + 4 * 28

y = 14

There are 2 zeros so there are 2 factors

( x- -4) ( x-8) = 0

(x+4) (x-8) =0
