Ineed with this question someone me

△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 .

The graph of h(x)= |x-10| +6 is shown. on which interval is this graph increasing

9/10 divide by -3/15 as a mixed number
