It seems that you are trying to solve for X. The first steps would be to use inverse operations in order to isolate and then solve for X. You would have to distribute the 4 into x+8, giving you 4x+32-4 = 34-2x. Then simplify it a bit, giving you 4x+28=34-2x. Add 2x to both sides and subtract 28 from both sides. This gives you 6x=6. Divide by 6 on both sides and you get X=1.


Answer: X=1

Not sure exactly what you are supposed to be doing but, I foiled the 4(x+8) and it became 4x+32-4=34-2x. I then did 32-4 which makes it 4x+28=34-2x. Then I added 2x to both sides making 6x+28=34 and then subtracted 28 from both sides making 6x=6 then divided both sides by 6 and got x=1.

4.b.

Answer:  See below.

Step-by-step explanation:

<h2><u>For the equation f(x) = 2x</u></h2>

3.a.  f(6) means use x = 6 in the equation f(x) = 2x

so f(6) would be f(6)= 2(6)

<u>f(6) = 12</u>

3.b.  f(-11) = 2(-11)

<u>f(-11) = -22</u>

3.c.  f(2.75) = 2(2.75)

<u>f(2.75) = 5.5</u>

3.d.  This is turned around.  We are told f(x)=20, so what would x need to be for f(x) to be 20?  Since f(x) = 2x, we can say 20 = 2x.  Therefore x = 10

f(10) = 20

<u>The rest of (3) are solved in the same fasion.h</u>

<u></u>

<h2><u>For the equation  f(x)= 5x+50</u></h2>

4.a.  f(7) = 5(7)+50

<u>f(7) = 85</u>

4.b. f(-12)

  f(-12) = 5*(-12)+50

<u>f(-12) = -60</u>

<u></u>

Continue in the same fashion for these types of problems.
