A substance undergoes a chemical change. The result is a new substance with new properties. However, when a substance undergoes a physical change, it is often reversible. The substance has new physical properties, but its chemical properties do not change.

Brainliest ! which of the coordinates are not of th vertices of the feasible region for the system of inequalities y≤4,,x≤5,x+y> 6 a(2,4) b(0,6) c(5,4) d(5,1)

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
