Answer:
y = 2x - 12
Step-by-step explanation:
To find the inverse of a function, you switch x and y and solve for y.
x = 1/2 y + 6 switch x and y
x - 6 = 1/2 y subtract 6 from both sides
2x - 12 = y multiply both sides by 2
Answer: 1
Step-by-step explanation:
6 times 2 minus 2y = 10
first 6x2=12
12-2y=10
minus 12 from each side =0
so now you have;
-2y= -2
divide & you get one!
