Final answer:
To find the value of y when x is 9 in the equation y = (20)/(x - 19), first compute the denominator (9 - 19 = -10), and then divide the numerator by this result, yielding y = -2.
Step-by-step explanation:
The problem requires us to determine the value of y when x is given to be 9 according to the equation y = (20)/(x - 19). Plugging in the value of x into the equation, we get:
y = 20 / (9 - 19)
First, we calculate the denominator:
9 - 19 = -10
Then, we divide the numerator by the denominator:
y = 20 / (-10)
After performing the division, we find:
y = -2
Therefore, when x is 9, the value of y is -2.
