Converting an equation into inverse function, we need to interchange x with the y.
f(x) = 1/9x + 2
y = 1/9x + 2
Interchange x and y
x = 1/9y + 2
Get the y.
-1/9y = -x + 2
1/9y = x - 2
y = 1/9x - 2/9
So the final answer is
<span>y = 1/9x - 2/9</span>
Answer:
unit rate of lemonade to cranberry juice
= 5:1
Step-by-step explanation:
A recipe for fruit punch calls for 1/2 liter of lemonada and 1/10 liter of cranberry juice
1/2 liter of lemonada= 0.5
1/10 liter of cranberry juice = 0.1
unit rate of lemonade to cranberry juice
= 0.5/0.1
unit rate of lemonade to cranberry juice
= (5*10^-1)/(1*10^-1)
unit rate of lemonade to cranberry juice
= 5/1 *(10^-1)/10^-1)
unit rate of lemonade to cranberry juice
= 5/1
unit rate of lemonade to cranberry juice
= 5:1

X = number of years
78 + 7x = 111 + 4x
-78 from both sides
7x = 33 + 4x
Subtract 4x from both sides
3x = 33
Divid both sides by 3
X= 11
In 11 years both trees will be the same height.
