Find the inverse of h(x) = (2x + 6)/5

Answers

Answer 1

Answer:

Answer:

h^-1(x) = (5x - 6)/2

Step-by-step explanation:

To find the inverse of h(x) = (2x + 6)/5, we need to solve for 'x':

y = (2x + 6)/5 ⇒ 5y = 2x + 6 ⇒ 5y - 6 = 2x ⇒ x = (5y - 6)/2

Therefore, h^-1(x) = (5x - 6)/2

Answer 2

Answer:

Answer:

(5x-6)/2

Step-by-step explanation:

h(x) = (2x + 6)/5

y = (2x + 6)/5

To find the inverse, exchange x and y

x = (2y+6) /5

Then solve for y

Multiply each side by 5

5x = (2y+6)/5*5

5x = 2y+6

Subtract 6 from each side

5x-6 = 2y+6-6

5x-6 = 2y

Divide by 2

(5x-6)/2 = 2y/2

The inverse is

(5x-6)/2

If Walt can paint 25 feet of fence in an hour, and Joe can paint 35 feet in an hour, howmany minutes will it take them to paint a 150-foot fence, if they work together?

Answers

If Walt paints 25 ft. on one hour, and Joe pairs 35 ft in an hour, then they paint 60 ft per hour together. So, 60ft divided into the 150 ft fence equals 2 1/2 hours.

It will take Walt & Joe 2 1/2 hours to paint a 150ft fence.

The answer is 2 and a half hours
