X+y+z = 132
x = 7+z
y = 3z

(7+z)+3z+z = 132
5z = 132-7
z = 125/5

z = 25 <=====

x = 7+z
x = 7 + 25

F(x) = -2|x-2|+4 vertical stretch by a factor of 2

stepladder [879]

A vertical stretch by a factor of 2 of F(x) = -2|x-2|+4 would result in the revised function G(x) = -4|x-2|+4. The vertex would stay in the same place (2,4).

torisob [31]

The first carpenter is 0.4464 of the way is ahead of the second carpenter

Solution:

Given, Two carpenters are building a fence

After 5 minutes, one carpenter is finished 4/7 of the way

Second carpenter finished 1/8 of the way

Now, let us find the work done by each carpenter

$\begin{array}{l}{\text { For } 1^{\text {st }} \text { carpenter }=\frac{4}{7}=0.5714 \text { approximately. }} \\\\ {\text { For } 2^{\text {nd }} \text { carpenter }=\frac{1}{8}=0.125}\end{array}$

Then, extra work done by first carpenter over second carpenter = work done by first carpenter – work done by second carpenter

= 0.5714 – 0.125 = 0.4464

Hence, the 1st carpenter is 0.4464 of the way is ahead of the 2nd carpenter
