The table shows global mean temperature (inC) every five years beginning in 1950. Find the mathmaticle model that best fits the data and use it to predict the global mean temperature in 2015. Code 1 for 1950, 2 for 1955, and so on

△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 .

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?

Consider the expression below. 9 + 4(x + 2) – 3.1 select the term that best describes "3" in the given expression. o a. coefficient variable exponent constant
