Answer:
Step-by-step explanation:
To find the inverse function, the first step we do is change f(x) to Y. So now, we have
y=2x+1
Now that we have this function, we simply flip x and y. When we do that, we get
x=2y+1
Now that we have this function, we just solve for Y. We do that by bring 1 to the other side by subtracting it from both sides, then dividing both sides by 2.
x-1=2y+1-1
x-1=2y
(x-1)/2=2y/2
(x-1)/2=y
So, our inverse function is:
y=(x-1)/2, or y=x/2 - 1/2
Hope I helped!
It seems like u are correct, smart man
Answer:
The fraction is 32/27
Step-by-step explanation:
let the fraction be x/y
x - y = 6
x = 6 + y ••••••(i)
This is according to the first sentence
Furthermore;
x/y-5 = 3/2
2x = 3(y-5) •••••(ii)
Substitute
2(6 + y) = 3y - 15
12 + 2y = 3y - 15
3y -2y = 12 + 15
y = 27
x = 6 + y
x = 6 + 27 = 33
