Examine the system of equations. 6x + 11y = –57 –8x – 27y = 65 Sherri multiplied the first equation by 8 and the second equation by 6 to eliminate the x-variable. Could Sherri also multiply the equations by two different numbers to eliminate the x-variable? Which statements are true? Check all that apply. Yes, she could use 27 and 11. Yes, she could use 4 and 3. Yes, she could use –8 and –6. Yes, she could use –27 and –11. Yes, she could use –4 and –3. Yes, she could use 65 and 57. No, these are the only effective multipliers.

Step-by-step explanation:

Yes, she could use –4 and –3.

Are the correct answers..

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
