Which of the following represents the characteristics of the graph of x ≥ -9? closed circle on -9 and shaded to the left closed circle on -9 and shaded to the right open circle on -9 and shaded to the left open circle on -9 and shaded to the right

i think its open circle on -9 and shaded to the right.

He estimated that he had about $9 worth of groceries

Step-by-step explanation:

Given that

Gallon of milk =  $3.49

Three pounds of  oranges = $1.14(3) = $3.42

Box of cereal =  $3.46

Here the front end estimation should be applied that means only considered the number that shows in the front side and the remaining numbers should be zeros

Now applying the front end estimation, It shows like this

$3.49 => $3.00

$3.42 => $3.00

$3.46 => $3.00

Now sum of all 3 that comes 9

Therefore the second option is correct
