△abc is reflected to form △a′b′c′ . the vertices of △abc are a(-1, 3) , b(2, 4) , and c(-5, 6) . the vertices of △a′b′c′ are a′(3, −1) , b′(4, 2) , and c′(6, −5) . which reflection results in the transformation of △abc to △a′b′c′ ? a. reflection across the x-axis b. reflection across the y-axis c. reflection across y = x d. reflection across y=−x

Step-by-step explanation:

The given transfomation is

Notice that the rule of the given transformation is

That is, the coordinates were change of position, like an inverse.

According to transformation rules, this represents a reflection across the line .

Therefore, the right answer is C.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
