Triangle JOY is translated using the rule (x, y) → (x + 3, y − 2) to create triangle J′O′Y′. If a line segment is drawn from point J to point J′ and from point O to point O′, which statement would best describe the line segments drawn in relation to one another? They share the same midpoints.
They create diameters of concentric circles.
They are parallel and congruent.
They are perpendicular to each other.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

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.
