Answer: x = -2

Step-by-step explanation:

x=4+(4x-4)\frac{1}{2} \\x=4+\frac{4x}{2}-\frac{4}{2}\\x=4+2x-2\\x=2+2x\\x-2x=2\\-x=2\\x=-2

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

4x + y = 2

y = x - 3

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                    4x + (x - 3) = 2
  2. Combine like terms:           5x - 3 = 2
  3. Isolate <em>x</em> term:                     5x = 5
  4. Isolate <em>x</em>:                              x = 1

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    y = x - 3
  2. Substitute in <em>x</em>:                       y = 1 - 3
  3. Subtract:                                 y = -2

Given the function f(x) = 4(x+3) − 5, solve for the inverse function when x = 3. (1 point)
atroni [7]

the function f(x) = 4(x+3) − 5

Lets find the inverse function f^-1(x)

step 1: Replace f(x) with y

y = 4(x+3) − 5

step 2: Replace x  with y and y with x

x = 4(y+3) - 5

step 3: Solve for y

x = 4(y+3) - 5

x = 4y +12 -5

x= 4y + 7 (subtract 7 on both sides)

x - 7 = 4y (divide by 4 on both sides)

\frac{x-7}{4}=y

f^{-1}(x)=\frac{x-7}{4}

Given : x = 3

We plug in 3 for x in the inverse function

f^{-1}(x)=\frac{3-7}{4} = -1

the inverse function when x = 3  is -1

Combine like terms . what is 43z + 15z + 7z + 5z + 46z + 14z? ​
Vladimir [108]

Basically just add them all together like normal addition except there is a z attached to each number:

43z + 15z + 7z + 5z + 46z + 14z

58z+ 7z + 5z + 46z + 14z

65z + 5z + 46z + 14z

70z + 46z + 14z

116z + 14z

130z

Hope this helped!
