You borrowed 90 dollars from your grandmother. you pay back 15 dollars each week. write in standard form an equation in which y is the amount of money owed after x weeks.

The table respent two linear functions the equation respented by the first tables is given

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

If a is a nonzero real number then the reciprocal of a is
