Step-by-step explanation:
With each iteration, you're swapping the two coordinates, and then change sign of the first one:
First transformation
- Start with (3,1)
- Swap coordinates: (1,3)
- Change sign of the first coordinate: (-1,3)
Second transformation
- Start with (-1,3)
- Swap coordinates: (3,-1)
- Change sign of the first coordinate: (-3,-1)
Third transformation
- Start with (-3,-1)
- Swap coordinates: (-1,-3)
- Change sign of the first coordinate: (1,-3)
Answer:
The correct option is C: the isotope of iodine contains 81 neutrons.
Step-by-step explanation:
The mass (A) of the iodine isotope is given by:

Where:
Z: is the number of protons
N: is the number of neutrons
For iodine Z= 53, so if A = 134 the number of neutrons is:

Therefore, the correct option is C. The isotope of iodine contains 81 neutrons.

Answer:
There are 180 degress in a triangle. so minus the angles given from 180 to find X.
X = 180 - 106 - 30
X = 44 degrees
Answer:
A system of linear equations is just a set of two or more linear equations. In two variables (x and y) , the graph of a system of two equations is a pair of lines in the plane.
Step-by-step explanation:
The lines intersect at infinitely many points. (The two equations represent the same line.)
