There are 10 girls and 15 boys on a swim team. An out-of-state competition requires a team consisting of 5 girls and 7 boys. How many different ways could these 12-member teams be formed to send to the competition?

step-by-step explanation:

translate k to n and reflect across the line containing jk.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
