False
Take RHS = 6 x 105 + 6 x 102 = 6 x 100000 + 6 x 100 = 600000 + 600 = 600600 ≠ LHS Hence, RHS ≠ LHS
Hoped that helped!

First you have to realize that when x>0 y becomes = - 2*x for any value of x greater than 0. Also true is that the circle representing the end point is open. With those two facts, only top left and bottom right can be true. Of those 2, the answer is top left because the point at 0 is open.
Answer: The height is about 25 cm.
Multiply the first equation by 2:-
2y + 4.6 = 0.90x
2y - 0.90x = -4.6
second equation is
-2y - 4.2x = -7.8
Adding:-
-5.1x = -12.4
x = 2.4
-2y = -7.8 + 4.2(2.4) = 2.3
x = -1.2
Answer x = 2.4 and y = -1.2
