Answer:

<h2>The x-coordinate after the rotation is -10.</h2>

Step-by-step explanation:

A 810° rotation is equal to a 90° rotation. So, the transformation described gives the same result than rotating 90° only.

A 90° counterclockwise rotation is defined by the rule

$(x,y) \implies (-y,x)$

The given coordinate is $(8,10)$ . Using the rule, we have

$(8,10) \implies (-10,8)$

Therefore, the x-coordinate after the rotation is -10.

Answer:

53/5

Step-by-step explanation:

since 10 is the denominator of the denominator we can move it to the numerator, giving us 10n/5-3n = 1/5

multiply all sides by 5-3n, giving us 10n = (5-3n)/5

now multiply by 5 to get rid of the final denomintor, 50n = 5-3n

move 3n to the other side 53n = 5, n = 53/5
