Answer:

x = -50/9    

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

3x - 8 - 12x = 42

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    -9x - 8 = 42
  2. Isolate <em>x</em> term:                              -9x = 50
  3. Isolate <em>x</em>:                                        x = -50/9

The sum of r and t is equal to 42. Let r = 25. What is the value of t?
Anni [7]
R + t = 42
r = 25

Plug in 25 for r

(25) + t = 42

Isolate the t by subtracting 25 from both sides

t + 25 (-25) = 42 (-25)
t = 42 -25
t = 17

Hope this helps

Which equation is the inverse of y = 100 - x??
denis-greek [22]

For this case we must find the inverse of the following function:

y = 100-x

To do this, we follow the steps below:

We exchange the variables:

x = 100-y

We clear the variable "x" (the variable is already cleared):

x = 100-y

We change "x" to "y":

y = 100-x

We change y for f^{-1}(x):

f^{-1} (x) = 100-x

ANswer:

f^{-1} (x) = 100-x
