Answer:

x=3

Step-by-step explanation:

so in order to solve this question we are going to plug in u for 2^x

3((2^x)/2)=2^x+4

3u/2=u+4

3u=2u+8

u=8

we can put 2^x back into the equation in order to find x

2^x=8

2^x=2^3

x=3

Which one is the right answer?
Artemon [7]

Answer:

the answer is C

Step-by-step explanation:

book = $12.99

DVD = $17.99

total bill

= $4.99 + $12.99 + 17.99

= $35.97

tax 6%

amount of tax

= 6% × total price

= 6/100 × $35.97

total bill including 6% tax

= total bill + amount of tax

= $35.97 + $2.16

= $38.13

Using the function below, evaluate f(-2). *<br> 2 points<br> f(x) = 3x? - 5x - 2
monitta
Okay so I'm guessing that they are two different formulas the f(x)= 3x and the f(x)= -5x-2. If that's is true then you would just have to plug in -2 to the x's. So then it would be f(x)= 3(-2) which if you solve it would give you f(x)= -6 and for the second one it would be f(x)= -5(-2)-2 so then you would solve for it and get f(x)= 8.
