Evaluate the given integral by making an appropriate change of variables. x − 2y 3x − y dA, R where R is the parallelogram enclosed by the lines x − 2y = 0, x − 2y = 10, 3x − y = 1, and 3x − y = 4

Kylie explained that (-4x+9)^2 will result in a difference of squares because (-4x+9)^2 (-4x+9)^2 =(-4x)^2+(9)^2=16x^2+81

Solve 2^x=32 and rewrite this equation in a logarithmic form

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
