PLEASE HELP Determine which equation below has a solution of x = 1/2
A. 5x + 8 - 12x = -6x + 2x - 3
B. 3x - 1 - 4x= -2x + 7x-4
C.-4x-6 + x = -2x + x - 10
D. -3x – 8 + x= -4x + x - 10

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)

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."

the answer is 64 cm
