Simplify a - {b-[C- (d - e) - f - g).
O a+b+c-d+e-f+g
O a-b+ C-d + e-f+g
O a+b+c+d+e-f+g
O a-b+C-d + e +f-g

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

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)
