Ada is showing her work in simplifying (5.9 − 1.8) − 6.2 + 4.1. in which step did ada make an error?

step 1: (5.9 − 1.8) − 6.2 + 4.1

step 2: 5.9 + (−1.8 − 6.2) + 4.1 (associative property)

step 3: 5.9 − 8 + 4.1

step 4: 5.9 + 4.1 − 8 (associative property)

step 5: 10 − 8 = 2

i got 142 as my answer

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?
