Remember y ou can do anything to an equation as long as you do it to both sides
get 1x by itself
8x-12=4x+24
add 12 to both sides
8x=4x+36
minus 4x from both sides
4x=36
divide both sides by 4
x=9
Smith's balloon is an algebraic expression
The expression that represents how many Balloons Smith has is p + 20
<h3>How to determine the number of ballons?</h3>
The given parameters are:
Small = p
Big = 20
Add the number of small and big ballons to get the total number of ballons
Total = Small + Big
This gives
Total = p + 20
Hence, the expression that represents how many Balloons Smith has is p + 20

Answer: D.) 
Step-by-step explanation: We are given an exponential function f(x).
g(x) is an exponential function that is being reflected across y-axis.
According to rules of transformations y=f(-x).
That is variable x is being multiplied by a negative sign.
In the given options
, the variable x is being multiplied by a negative sign.
Therefore, correct option is D option.
