If y = 5x − 3, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs? {(2, 5), (−3, −12), (−4, −18)} {(−1, −8), (0, −3), (3, 12)} {(1, 4), (7, 25), (3, 10)} {(5, 20), (6, 12), (1, 9)}

step-by-step explanation:

if x = 2 you have to find x to finish the problem

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

details

step-by-step explanation:

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.
