Answer:
A
Step-by-step explanation:
Your friendly local graphing calculator or spreadsheet can tell you the quadratic regression equation. It best matches choice A.
Answer:
x = your number
3 / ( x + 8 ) = 2 / ( x + 3 )
Cross multiply
3 ∙ ( x + 3 ) = ( x + 8 ) ∙ 2
3 x + 9 = 2 x + 16
Subtract 2 x to both sides
x + 9 = 16
Subtract 9 to both sides
x = 7
