Answer:
f(x) = (x − 3)² − 11
Step-by-step explanation:
To convert to vertex form, complete the square.
f(x) = x² − 6x − 2
f(x) = x² − 6x + 9 − 9 − 2
f(x) = (x − 3)² − 11
We have y = -2 - 2x ;
Then, x + ( -2 - 2x ) = 5 ;
x - 2 - 2x = 5;
- x - 2 = 5 ;
-x = 7 ;
x = - 7;
Finally, y = - 2 - 2 × ( - 7 ) ;
y = - 2 + 14 ;
y = 12;

Answer:
2.5%
Step-by-step explanation:
In order to find the interest rate of a thing, you divide the first value by the second. This gives you 0.025, which is roughly 2.5%. 10% and 25% wouldn't make sense, as those are 6 and 15 dollars, so they aren't applicable.
