Find an equivalent system of equations for the following system:
3x + 3y = 0
−4x + 4y = −8
3x + 3y = 0
7x − y = 8
3x + 3y = 0
−7x − y = 8
3x + 3y = 0
−7x + 7y = 8
3x + 3y = 0

Step-by-step explanation:

An equivalent system refer to other system that has the same values for the variables, or it's satisfied by the same values. First, we calculate what are the values for x and y, in the given system.

Extracting common factors:

Now, summing both equations we have:

Replacing this value in a equation we have:

Now, we have to find the other system that it's satisfied by and  .

As you can see, the first system is equivalent because it has the same solution as the given system of equations.

Therefore, the correct answer is the first one.

A and B

Step-by-step explanation:

An equivalent system of equation is found by adding or subtracting the second equation or when any multiple of both equations are added or subtracted to each other.

Let us see part by part.

A.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
