Bryan’s volunteer group can build a garage in 12 hours. sequoia’s group can build it in 16. how long would it take them if they worked together?

3x + 4y -25 =0 represents the amount of change sianna should recieve

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
