Yes this is a function. Specifically, it is a linear function. It graphs a straight line. It is impossible to pass a single vertical line through more than one point on this graph. So it passes the vertical line test confirming we have a function.

Any input x leads to exactly one output y.

<h3>Final value : x² -9x - 11</h3>

$\frac{1}{(x - 2)} + \frac{1}{(x + 3)} = \frac{1}{5}$

$\frac{(x + 3) + (x - 2)}{(x - 2)(x + 3)} = \frac{1}{5}$

$\frac{2x + 1}{ {x}^{2} + 3x - 2x - 6 } = \frac{1}{5}$

$\frac{2x + 1}{ {x}^{2} + x - 6} = \frac{1}{5}$

2x + 1 = ⅕ × (x² + x - 6)

2x + 1 = ⅕x² + ⅕x - 6/5

1/5x² +1/5x - 2x - 6/5 - 1 = 0

1/5x² -9/5x - 11/5 = 0

x² - 9x - 11 = 0. #times by 5

Over the course of 8 races, a runner's finishing time was 5 seconds faster each race than the race prior. if her combined total

ANEK [815]

X+(x-5) +(x-10) ...
This adds up to 8x -140 seconds where x is the 1st race time.
This adds up to 44:20 minutes
44mins * 60 sec/min = 2640 seconds + 20 = 2660 seconds cummulative
8x - 140 = 2660 8x =2800 sec
8x = 350 seconds or 4.5mins for the 1st race
Race 2: subtract 5 seconds yields 4 mins 25 seconds
