Answer:
Step-by-step explanation:
To find the inverse of a function you must first swap the places of x and y
Now solve for y
Step 1: Flip the equation.
Step 2: Subtract 9 from both sides.
" of " means multiply
1/10 * 3.1 = 3.1/10 = 0.31 <===
Independent variable: 1 tsp. salt
dependant variable: bubble solution
Because you're adding the salt to the solution, the salt is independant. that's what is making the change. the dependant variable is what is being tested; the bubble solution.
It would be: 11 1/9 = 100/9
So, Your Final Answer would be 100/9
Hope this helps!
4/3*56/X. Cross multiply then divide. 4X=168/4X. X=42 minutes to wash
