3x - 4y = -5
y = 4x - 2
is (1,2) a solution of the system?

Replace x with the given x value in the solution to see if it equals the Y value given in the solution:

3x - 4y = -5

3(1) - 4(2) =

3 - 8 = -5

True.

y = 4x-2

y = 4(1) - 2

y = 4-2

y = 2

True.

Yes (1,2) is a solution.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
