(4,3) is a solution to the following system of equations: 2x+ y = 11
y=x-1
true or false

True

Step-by-step explanation:

Substitute the x and y values of the point into the first equation and the x value of the point into the second equation. If both equations are satisfied then the point is a solution.

2(4) + 3 = 8 + 3 = 11 ← True

y = 4 - 1 = 3 ← True

Thus (4, 3 ) is a solution to the system of equations.

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.
