Which ordered pair is the best estimate for the solution to the system? (0, 7) (−4, 212) (−412, 212) (0, −2) a system of 2 linear equations graphed on a coordinate plane. the horizontal x-axis ranges from negative 5 to 5 in increments of 1. the vertical y-axis ranges from negative 5 to 5 in increments of 1. one line passes through begin ordered pair negative 5 comma 0 end ordered pair and begin ordered pair 0 comma negative 2 end ordered pair. second line passes through begin ordered pair negative 2 comma 4.667 end ordered pair and begin ordered pair negative 5 comma 1.667 end ordered pair.

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.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
