Which of the following equations has the solution set {0}?

-14m - 7m + 1 = -7m + 1
-14m + 7m + 1 = -7m + 2
14m - 7m - 1 = -7m + 1

It would be the first one because the second one has a 2 and we know that the 2 does not cancel out the one. This leaving us with 2 answers left. The 3rd one is not the correct one, this is because when you subtract the 14m - 7m you get 7m - 1, then you would subtract the 7m and -7m because the ones canceled each other out. This leading us to get -14m and not a 0. This leaving the last one, which is the first one. This having to be the first one is correct.

(I did this on a test and got it right) (It's the first one)

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

the answer is (-4,-4)

hope this ! : d
