Answer:
0.71. with the bar notation over the 1
Step-by-step explanation:
The formula for direct variation is y = kx<span> where k </span>≠ 0
y = 9/x is an inverse relation
Step-by-step explanation:
1) first eliminate constant(number without variable) you eliminate constant by doing the inverse operation(if constant is being added, then subtract)(if constant is being subtracted, then add it)
ex: if x+9=32
subtract 9 from both sides to get rid of it
x=23
2) if there is another constant but this constant is being multiplied/divided then do the opposite operation to remove it
you could multiply by 3 on both sides:
x+9=69
x=60
The answer is -1 because it is subtracting by -2
