2(2) + 3(3) =
4 + 9 = 13

Answer:
Compounds contains atoms from different elements. The elements are bounded chemically. H20, stands from a hydrogen atom and two oxygen atoms bonded together. These are two different elements and therefore the combination of H20 fits the definition for a compound.
Answer: y=(x-1)/2
Step-by-step explanation:
To find the inverse, you want to switch the y with x and x with y. Then, you solve.
y=2x+1 [switch y with x and x with y]
x=2y+1 [subtract both sides by 1]
x-1=2y [divide both sides by 2]
(x-1)/2=y
Now, we know that y=(x-1)/2 is the inverse.
