Answer:

  (a) 422 / 495, rational

Step-by-step explanation:

The two-digit repeating decimal 0.2525... is equivalent to those two digits over an equal number of 9s: 25/99.

When 3/5 is added to that, the result is ...

  25/99 +3/5 = (25(5) +99(3))/(99·5) = (125 +297)/495 = 422/495

The sum of two rational numbers is always rational.

How do I solve this problem? The green dots can be moved
olganol [36]

Answer :

Points at (1, 3) and (3, 3) and (2, 1)

Explanation:

The original graph (dashed) is an absolute value function meaning f(x) = |x|

<u>Given:</u> y = 2f(x - 2) + 1

f(x - 2) means you plug in x - 2 for x in f(x) function

the new graph equation is: y = 2|x - 2| + 1

  • The graph will shift up 1 because +1
  • The graph will shift right because -2
  • The graph has a scale factor of 2
  • The graph is V shaped because it is an absolute value graph
