Alisson is normally given $x each month; but in November she was given $9 more than thrice her usual amount. In November she was give

Alisson

In November, Alisson was given $12.

Step-by-step explanation:

The normal amount given to Alisson each month = $x

If in November Alisson was given $9 more than thrice her usual amount of $x, it implies that she was usually given $3 ($9/3) per month because $9 is three times (thrice) than $3.

Therefore, Alisson's usual amount per month which is  $x = $3

This implies that in November she was given $12 ($3 + $9), which was thrice more.

To check the correctness of the above reasoning, we recall that $12 is more by $9 than $3, and $9 is thrice than the $3 given to Alisson per month.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
