That's simple!!!
-12/19 = b/19
as denominators are same, you can cancel that.
b = -12

Shift the graph of the function y = x², 5 units down /look at the picture #1/.
/look at the picture #2/ - your answer
Answer:
xy = - 8
Step-by-step explanation:
note that
(x - y)² = x² + y² - 2xy , that is
6² = 20 - 2xy
36 = 20 - 2xy ( subtract 20 from both sides )
16 = - 2xy ( divide both sides by - 2 )
- 8 = xy
They all consist of 1's, 0's, and decimal points.
