2x-3yi=14+12i
=> 2x=14; -3yi=12i => x=7; y=-4
Answer:
The final price of money of t shirt that I own = $ 16.69
Step-by-step explanation:
Given in question as ,
The t shirt cost to the owner = $12
The markup percentage = 30%
So, now the cost price of t shirt = 30% of 12 + 12
= 3.6 + 12 = $15.6
Tax which is added now = 7%
So, new cost of t shirt = 7% of 15.6 + 15.6
= 1.092 + 15.6 =$ 16.69
Hence , the final price of money of t shirt that I own = $ 16.69 Answer
You need to provide a picture or something
We actually don't need to do any computation. By definition, the inverse function 
changes the role of input and output. So, if a function f maps x onto y, the inverse function maps y onto x.
You have to think like this: if the function makes a step further, the inverse function makes that same step back.
This means that the composition 
is always the identity function 
. In fact,
So, for every function, you have
12 x 2 = 24
When you multiply two negative numbers, the answer will be a positive
When you multiply one negative and one positive, the answer will be negative.
Using that rule:
(-12)(-2) = 24
24 is your answer
hope this helps
