Write the coefficient of y in the expansion of (5-y)^2.

If f(x)= sqrt4x+9+2, which inequality can be used to find the domain of f(x)?

Give me the equations of two lines that have the same slope but are not parallel.

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
