Answer:
12.5
Step-by-step explanation:
y varies inversely as x.
y = k/x
10 = k/20
200 = k
The constant proportion k is 200.
16 = 200/x
Cross multiply.
200 = 16x
200/16 = x
x = 12.5
I believe the answer is 2 since it is half of it and so you’d just be doubling it but I may be wrong
values of the variable that cause the polynomial to evaluate to zero.
