Answer:
y = -1/3x + 4
Step-by-step explanation:
y = 3x +5
current slope m is 3, perpendicular is opposite inverse which is -1/3
Passing through (6,2):
y = mx + b
2 = -1/3(6) + b
2 = -2 + b
b = 4
Use the perpendicular m = -1/3 and b = 4 to form equation of line:
y = mx + b
y = -1/3x + 4
The train is going 60 mph and the train is going 45 mph

Answer:
750 sheets
Step-by-step explanation:
2.5 kilograms=2.5*1000=2500 grams
2500/40=62.5 stacks-of-12-papers
62.5*12=750 sheets of paper
To check our work:
Let's set x as the weight of one sheet of paper.
12x=40 grams, x= 3 1/3 (three and one thirds) grams
3 and 1/3 *750= 2500 grams
2500 grams=2.5 kilograms
⇒I will first isolate y together with its coefficient k by placing 
to the right hand side...
⇒Now to leave y independent we have to divide ky by the coefficient of y which in this case is k.
⇒Meaning k will divide all the terms in the equation.
⇒Attached is the answer.
