Solve the system by substitution, if possible. (If the system is inconsistent, enter INCONSISTENT. If the system is dependent, enter a general solution in terms of x or y.) 3x − y = 12 y = 3x − 12

step-by-step explanation: it is d

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:
