4. Visualize a balance scale with an equal number of 1-gram weights on each pan.
What would happen to the scale if 2
weights were removed from the left
side? What can be done to the right side
of the scale to put it back into balance?
A

The equation respenting the left table is

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14

Which of the following will form the composite function?
