Very important! 50 points and brainiest to first !

a company manufactures and sells video games. a survey of video game stores indicated that at a price of $71 each, the demand would be 200 games, and at a price of $31 each, the demand would be 1,000 games. if a linear relationship between price and demand exists, which of the following equations models the price-demand relationship?

a) y= 20x
b) y= 20x - 1,220
c) y= -20x + 1,620
d) y= -20x + 1,220

entering that problem on the tube might get you an answer

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.
