Travis milks his cows each morning. He has never gotten fewer than 3 gallons of milk; however, he always gets fewer than 9 gallo

Hatshy [7]

Answer:

x-3 < 9

Step-by-step explanation:

if we know that the liters of milk are 3 or more and less than 9, we have

3=< x <9 where x are the liters of milk.

if we subtract 3 in inequality,

x-3 < 6 with x greater than or equal to 0 because we are talking about a quantity

to solve this inequality, we have to clear x

x < 6+3 = 9 So x < 9 where x belongs to natural numbers

What is the inverse of the function f(x)=2x+1

riadik2000 [5.3K]

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!
