Question

Is (1,2) a solution to both equations?

A) Yes
B) No
C) Cannot be determined
D) Insufficient information

Answer 1

The point (1,2) is not a solution to both equations.

Step-by-step explanation:

The given question is asking whether the point (1,2) is a solution to two equations or not. To determine this, we need to substitute the values of x and y from the point (1,2) into each equation and check if the equation holds true.

Let's plug in the values of x=1 and y=2 into each equation:

A. y = -3x: 2 = -3(1) = -3

B. y = 0.2 + 0.74x: 2 = 0.2 + 0.74(1) = 0.94

Since neither equation holds true when the values of x=1 and y=2 are substituted, the answer is B) No, the point (1,2) is not a solution to both equations.
