An architect represents a 9 inch height as inch on a scale drawing. Which of the following scales did the architect use?

1 foot =1/36 inch
1 foot = 1/9 inch
1 foot = 1/2 inch
1 foot = 1/3 inch

Find the solution of this system of equation -7x+y=-20 9x-3y=36

What is the equation of the line in point-slope form? y+ 4 = 1/2(x+4) y-4 = 1/2(x + 4) y-0 = 2(x - 4) y-4 = 2(8-0)

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
