Find the value of x. round the length to the nearest tenth. the diagram is not drawn to scale. show your work.

id love for someone to explain how to solve this so i can get a better understanding! in advance : )

△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 .

Suppose a least-squares regression line is given by modifyingabove y with caret equals 4.302 x minus 3.293. what is the mean value of the response variable if xequals20?

In the triangles, bc =de and ac fe.if the mzc is greater than the mze, then ab isdfelth
