Two rival cleaning companies charge to dust houses. Captain Dustsalot charges $20 per house call plus $ 12 per room, and Dedusters charges $30 per house call
plus $10 per room. Abigail wants to know how many rooms she must get dusted
so that Captain Dustsalot is more expensive than Dedusters. Which inequality
should she use to figure this out if x represents the number of rooms she gets
dusted?

cosine

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 2/54
