Describe how to estimate a non-perfect square root to the hundredths place without using a calculator.

△cde maps to △stu with the transformations (x, y) arrowright (x − 2, y − 2) arrowright (3x, 3y) arrowright (x, −y). if cd = a + 1, de = 2a − 1, st = 2b + 3 and tu = b + 6, find the values of a and b. the value of a is and the value of b is .

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

Find solution of the linear equation y = 2/3x + 1/3
