Answer: (x, y) transforms into (-x, y)

Step-by-step explanation:

When we do a reflection over a given axis, the distance between the initial point to the axis must be the same as the distance of the reflected point to the axis.

So if we do a reflection over the y-axis, then the value of y must be fixed.

So if we start with the point (x, y), the only other point that is at the same distance from the y-axis is the point (-x, y)

So the rule is, the y value remains equal and the x changes of sign.

L * L = A
L * L = 1600
L^2 = 1600
√L^2 = √1600
L = 40 feet

Answer: The length of each side is 40 feet.

Btw: <em />this was your question "<em>A square garden has an area of 1600 feet length of each side"</em>

Sidana [21]
Equation that represents therelationship between the nmber of weeks and total amount of money marcus will have saved is

Y= 5x+42

-5x +y =42

He currently has $42 with planning to save $5 each week. So, $5 per week is the slope and $42 is the y intercept.
