What is the solution of the system pf equations y=-4x+6 y= -5x - 4

For this case we must indicate the solution of the following system of equations:

Equating both equations we have:

Adding 5x to both sides of the equation:

Subtracting 6 from both sides of the equation:

We look for the value of y:

Thus, the solution is:

good luck on your studies! : )

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
