I believe it is A; Its x- and y- coordinates are 2 times the correspopnding coordinated of the triangle RST.

Step-by-step explanation:

It just seems the most plausible. I am also taking the Quiz right now.

11) (2, 5);
21) (−1, 4);
31) Q(5, −8), S(−1, 3);
41) S is R reflected across the x-axis; only the signs of the y-coordinates of R and S are different;
51) Coordinate grid shown from negative 2 to positive 2 on the x-axis and negative 2 to positive 2 on the y-axis in increments of 1 over 4. Only the whole numbers are labeled. A point A is shown at the intersection of 2 grid lines to the right of the y-axis and 5 grid lines below the x-axis;
61) -4/8;
71) A coordinate grid from negative 3 to positive 3 on both axes is drawn in increments of 1 over 2. Point A is plotted 2 grid lines to the right of the y-axis and 4 grid lines above the x-axis. Point B is plotted at 6 grid lines to the right of the y-axis and 1 grid line below the x-axis. Point C is plotted at 6 grid lines to the left of the y-axis and 1 grid line below the x-axis;
81) (0.4, −1.8);

C

Step-by-step explanation:

The points of intersection of Carl’s graph have the same x-coordinates as the points of intersection of Shelly’s graph but different y-coordinates.

5. Expert says:

y=mx+b

m slope

b y-intercept

6. QueenB7591 says:

(-8, 0) and (-2, 0)

Step-by-step explanation:

The root of a parabola are the places at which the parabola intersects the x-axis. As one can see, on the graph these points are the following: (-8, 0) and (-2, 0). Thus, the roots of the parabola are (-8, 0) and (-2, 0).

C

Step-by-step explanation:

The points of intersection of Carl’s graph have the same x-coordinates as the points of intersection of Shelly’s graph but different y-coordinates.

$To solve the trigonometric inequality sin?(x) -0.85, Carl graphed the equations y=sin(x) and y=-0.85$

9. Tf0273433 says:

The answer here is A. "Calculate the average of the x-coordinates and the average of the y-coordinates of the endpoints."

The midpoint is basically the point located between two endpoints, where the distance is equal from the midpoint to either of the points. Since this is merely a halfway point, taking the average of the coordinates would yield us the midpoint.
