Tom [10]

Absolute value of any number is always positive because it represent distance and distance will always positive.

To place chimney at  least 30 feet , the distance along the width of the roof  (x) will be  x = 17.5 feet or x = 2.5 feet.

Since, The height of the roof is described by the function f(x)=−4/3|x−10| + 40

Since, minimum height is 30 feet.

So , substitute f(x)=30 in above expression.

                 30=−4/3|x−10| + 40

                   4/3|x−10| = 10

                      |x−10|=30/4

                      |x−10| = 7.5

Taking positive case,

                           x−10 = 7.5

                           x = 17.5 feet

Taking negative case,

                          x−10 = - 7.5

                          x = 10 - 7.5

                          x = 2.5 feet

Answer this please!​
Troyanec [42]

f(x) = 4x + 3

That's one-to-one, a linear function that will give a different f(x) for each different x.

For the inverse let's swap x and y and solve for y

x = 4y + 3

x - 3 = 4y

y = (x- 3)/4

That's the inverse,

Answer:  (x- 3)/4, second choice

The domain and range of the inverse is all real numbers.  It's two lines; I'll leave the graphing to you.
