The solution of (3,13) means you need to create two lines that satisfy x = 3 and y = 13
The two lines can be anything as long as they give this solution
For example, if you wrote x + y = 16 (you know their values already)
Then write another y - x = 10
From here you have your equations, turn them into the f(x) form.
x + y = 16 can be turned into y = 16 - x which is f(x)=16-x
y-x = 10 can be turned into y = 10 + x which is g(x)=10 + x

Answer:
The answer is "Type 1 error".
Step-by-step explanation:
The error of type I, frequently known as a 'false positive': its error in judgment that perhaps a null hypothesis is simply rejected. This is the mistake of accepting a possible (actual interest hypothesis) hypothesis whenever the results could be attributed to chance since the researchers deny, if valid, the null hypothesis.
Answer:
x=3
y=-1
Step-by-step explanation:
first multiply the 2nd row by 2 so you will get
4x-4y=16
4x+2y=10
then subtract the 2nd row from the first row and so you will get
-6y=6
then solve for y in the above equation
y=-1
then substitute y=-1 into any 2 equations .
i picked the first 1
4x-4 × -1=16
then solve for x .
you will get
x=3
