Because you know what A is equal to in terms of B, you can replace the A in the first equation with b-2, since we know that that also equals A. This makes the new equation b - 2 - 3b = 28. You can simplify this to -2b = 30. This makes B = -15. if you put this into the second equation now, -15 - 2 = A. This makes A = -17. I hope I could help to explain and answer this!

3f+2g=30 and f+2g=26
tatuchka [14]
3f + 2g = 30 . . .(1)
f + 2g = 26 . . . .(2)

(1) - (2) => 2f = 4 => f = 4/2 = 2

From (2), 2 + 2g = 26 => 2g = 26 - 2 = 24 => g = 24/2 = 12

Therefore, f = 2 and g = 12

The coordinates of the vertices of LMN acquired a -ve sign to form the image L'M'N'. The line passes through the origin.

Step-by-step explanation:

When a point is rotated through 180° about the origin clockwise/anticlockwise, the coordinates of the object point T (h,k) takes a new position (-h,-k) to form the image T'. A line joining an object point to its image point will pass through the origin that is the center of rotation.
