All of the following expressions are equivalent, except ______.
oksano4ka [1.4K]

Answer:

x - 7

Step-by-step explanation:

Let's let x = 4 and see which one would be different

x - 7 = 4 - 7 = -3

7 + (-x) = 7 + -4 = 3

-x + 7 = -4 + 7 = 3

7 - x = 7 - 4 =3

As you can see, the top answer would be negative while all the rest are positive. This is because, in that case, the negative sign was attached to the 7 instead of the x.

If f(g(x)) = g(f(x)) = x, and<br> g(x) = 2 + In(x + 1), find f(4).
Dmitriy789 [7]

If f(g(x))=g(f(x))=x, then g and f are inverses of one another. So we know g(f(4))=4.

g(f(4))=2+\ln(f(4)+1)=4

\implies\ln(f(4)+1)=2

\implies f(4)+1=e^2

\implies\boxed{f(4)=e^2-1}

if anyone can solve this gets a $10 gamestop card i already got the codeSolve for x. Show each step of the solution. 2.5(10 - x)
schepotkina [342]

Remark

Forget the Gamestop. I'd never use it. This one is on the house.

Solution

2.5(10 - x) + 10 = 72 - 1.5x*(5x + 12)   The first step is to remove the brackets.  Be very careful you understand the bracket on the right.

25 - 2.5x + 10 = 72 - 7.5x - 18            Study the signs carefully. Collect like terms.

35 - 2.5x = 54 - 7.5x                   Add 7.5x to both sides.

35 - 2.5x + 7.5x = 54 - 7.5x + 7.5x

35 + 5x = 54                               Subtract 35 from both sides.

5x = 19                                        Divide by  5

x = 19/5

x = 3 4/5 = 3.8

Check

When you numbers are so cumbersome, you should check the answer.

<em><u>LHS</u></em>

2.5(10 - 3.8) + 10

2.5(6.2) + 10

15.5 + 10

25.5

<em><u>RHS</u></em>

72 - 1.5(5*3.8 +12)

72 - 1.5(19 + 12)

72 - 1.5(31)

72 - 46.5

25.5

<em><u>RHS = LHS</u></em> The solution checks.
