Liquid nitrogen has different properties from gaseous nitrogen. is it a chemical change when liquid nitrogen warms to gaseous
nitrogen?
yes, because chemical changes result in different properties.
no, because chemical changes do not result in different properties.
no, because the different properties are physical while the chemical properties remain the same.
yes, because warming is a chemical change even though the physical properties remain the same.

y=1/4x-4

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
