1 answer:
Ivanshal [37]3 years ago
3 0

Answer:

Step-by-step explanation:

(-14+\frac{3}{2}b)-(1+\frac{8}{2}b)=-14-1+\frac{3}{2}b-4b

                                   = (-15-\frac{5}{2}b)

(5+2b)+(2b+\frac{3}{2})=(5+\frac{3}{2})+(2b+2b)

                             = (4b+\frac{13}{2})

(\frac{7}{2}b-3)-(8+6b) = (\frac{7}{2}b-6b)-(3+8)

                             = (-\frac{5}{2}b-11)

(-10+b)+(7b-5)=(-10-5)+(b+7b)

                               = (8b-15)

Mr. Jones wants to place a chimney on his roof. It is recommended that the chimney be set at a height of at least 30 feet. The h
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
