What is the inverse of the function? f(x)=3x−1

Mathematics
1 answer:
Hatshy [7]2 years ago
5 0

Answer:

The inverse is 1/3 (x+1)

Step-by-step explanation:

y = 3x-1

Exchange x and y

x = 3y-1

Solve for y

Add 1 to each side

x+1 = 3y-1+1

x+1 = 3y

Divide each side by 3

(x+1)/3 = 3y/3

1/3(x+1) =y

The inverse is 1/3 (x+1)

Need help with figuring out this zingoes problem asap, willing to give brainliest!
muminat

Answer:

The yellow trapezoid, blue rectangle, and whatever that purple thing is are zingoes

Step-by-step explanation:

As far as I can tell, all the correct examples are

1) Symmetrical

2) Have a line splitting them symmetrically and does not go above or below the shape (Does that make sense?)

The wrong examples don't have any of the characteristics told above. For example, the square would be wrong because it doesn't even have a line

(P.S- This isn't my picture, just found it on the web. Shout out to whoever owns this)

We have , Three different golfers played a different number of holes today. Rory played 999 holes and had a total of 424242 strokes. Alicia played 181818 holes and had a total of 797979 strokes. Rickie played 272727 holes and had a total of 123123123 strokes. We have to find  , Which golfer had the lowest number of strokes per hole :

<u>Rory:</u>

Number of strokes per hole = \frac{424242}{999}  = 425

<u>Alicia:</u>

Number of strokes per hole = \frac{797979}{181818}  = 4

<u>Rickie:</u>

Number of strokes per hole = \frac{123123123}{272727}  = 451

Evelyn has dance class every Saturday. It lasts 1 hour and 40 minutes and is over at 12:45 P.M.
leva [86]

Answer:

Evelyn's dance class on Saturday starts at 11:05 A.M.

Step-by-step explanation:

I know this because if her class takes an hour and 40 minutes you would subtract the hour and 40 minutes from 12:45 so you could do 12 - 1 which equals 11. Then you would do 45 - 40 which equals 5. And last you would put the new times together so it would be, 11:05. Her dance class starts at 11:05 A.M.
