Answer:
kevin is 6 years old
Step-by-step explanation:
Let Kevin's age now be a
Daniel's age now be b
Kevin is 3 years older than Daniel. -> a-3 = b
Two years ago, Kevin was 4 times as old as Daniel -> a-2 = 4(b-2) = 4b -8
-> a-3 -(a-2) = b - (4b-8)
-> - 1 = -3 b +8
-> -9 = -3b
-> b = 3
-> a = 6
Answer:
8
Step-by-step explanation:
Take the biggest value and smallest value, and subtract the smallest value from the biggest value:
9-1=8
Answer: 
Step-by-step explanation:
To find the inverse of a function, you want to replace x with y and y with x. Then, you solve for y.
[replace y with x and x with y]
[subtract both sides by 7/2]
[multiply both sides by -2/3]
[distribute]

Now, we have our inverse function.
