Mathematics
1 answer:

Answer: x = 9, 5

<u>Step-by-step explanation:</u>

4 | x - 7 | + 2 | x - 7 | = 12

6 | x - 7 | = 12      <em>added like terms</em>

  | x - 7 | = 2       <em>divided both sides by 6</em>

x - 7 = 2         or         x - 7 = -2     <em>removed absolute value sign</em>

    x = 9         or               x = 5     <em>added 7 to both sides of both equations</em>

Consider the function,
RUDIKE [14]

Answer:

If x= 4 then f(x) = 4x -5 is 11.

Step-by-step explanation:

f(x) = 4x -5

We need to find the domain value that corresponds to the output f(x) = 11

In this question, we need to solve the expression for value of x such that the answer is 11.

if  x= 3

f(3) = 4(3) -5

     = 12 -5

    = 7

Since we want the answer 11 so we cannot take x= 3

if x = 4

f(4) = 4(4)-5

    = 16 - 5

    = 11

So, if x= 4 then f(x) = 4x -5 is 11.

A boat costs $11,850 and decreases in value by 10% per year. How much will the boat be worth after 8 years?
arsen [322]
11,850 x .9 = 11,605  

11605 x . 9 = 9,598.5       year 2 

9,598.5 x .9 = 8,638.65

8,635 x .9 = 7,774.785       year 4

7,774.785 x .9 = 6,997.31

6,6997.31 x .9 = 6297.58     year 6 

6297.58 x .9 = 5,667.82 

5,667.82 x .9 = 5,101.04 year 8
