Triangle DEF with vértices D(2,1), E(3,5), F(6,2) is reflected acreage the x-axis to make triangle D’E’F Which rule represents the transformation?
A. (x, y)—>( x,-y)
B. (x, y)—>(-x, y)
C. (x, y)—>(y,-x)
D. (x, y)—>(-y, x)

(Pls help I don’t understand)

your answer would be 12

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
