What is the solution to the system of equations? 3x-6y=-12 x-2y=-8 (a) use the substitution method to justify that the given system of equations has no solution. show all work! (b) what do you know about the two lines in this system of equations?

(a) Given system:

From (2), , substitute this value of x in (1), we get

Hence, the given system of equations has no solution.

(b) If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
