If you have a problem like:
4x+2y=20
2x+2y=16
You would subtract
4x-2y=20
-2x+2y=16
You would get the new problum
2x=4
You now want to divide the 2 on both sides to solve for x
x=2
Now that you've solved for X you want to solve for y. So use substitution to solve for y. You would want to substatute the x for the 2 in either of the problums. I'll use the first one.
4(2)+2y=20
You first want to multiply te 4(2) you would get a new problum.
8+2y=20
Now you want to subtract the 8 on both sides.
2y=12
The last step to solve for y is to divide the 2 on both sides.
Y=6
So your answers would be
x=2
y=6
The area of the triangular kite would be 12 feet
X is 9
12x + 17 = -1 + 14x
18 = 2x
x = 9
Answer
:we are told that every year the temperature rises by 0.08degrees Centigrade,
So the difference between margin of error and the increase is much higher
That is
0.15-0.08=0.07
But remember Margin of error=Critical value *Standard deviation of population
And it is a quantity that measures accuracy
So the counter argument is that this is still an increase and it should be considered.
