Answer:

  y was not substituted for every x

Step-by-step explanation:

To find the inverse of ...

  y = f(x)

you need to solve ...

  x = f(y)

Here, f(x) = x^2 +12x, so f(y) = y^2 +12y

This is not the expression we see on the right of ...

  x = y^2 +12x

Apparently y was not properly substituted into f(x).

It takes 12 people 15 hours to complete and certain job.how many hours would it take 18 people, working at the same rate to comp
pochemuha

Answer:

2 Hours

Step-by-step explanation:

Required man hours to complete the full job = 12 *15

                                                                           =180 Man hours

Required man hours to complete the 2/5 of the job = 180/5

                                                                                      = 36 Man hours

if 18 peoples are working,

required hours to complete the 2/5 of the job = 36 /18

                                                                            = 2 hours

4/5 N= 2/3. N = ?<br><br> 2/15<br> 5/6<br> 1 1/5<br> 1 7/15
Verizon [17]

Answer:

N = 5/6

Step-by-step explanation:

4/5 N= 2/3.  Find N (solve for N).  

Isolate N.  To do this, multiply both sides of the equation by (5/4):

(5/4)(4/5)N= (5/4)(2/3)

becomes N = 10/12, or N = 5/6.

Help me solve this <br><br>3-p/(-4) if p =12
kvv77 [185]
Since ur using 12 as p we solve it now.

3 - 12 over -4 = 6

Move the negative sign to the left (3 - (-12/4)
Simplify 12/4 to 3 ( 3 - (-3)
simplify brackets (3 + 3)
finally the answer is 6
