What is an equation of the line that passes through the points (5,5) and (5,-8)

x=5

Step-by-step explanation:

First, find the slope. This is your expression: -8-5/5-5. -8-5= -13, and 5-5 = 0. So, your slope would be -13/0. Since the denominator is a 0, the slope is undefined. That means it's a vertical line. Because it's a vertical line, your equation would just be x=5. Hope this helps!

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.

the surface area is 124cm²

length: 4cm

width: 9cm

height:   2cm
