For all 3 questions, we will use the section formula.

If the store can only buy them in bulks of ten, then you take your number of desired cars (3,000) and divide it by the bulk amount (10) and it will give you your amount of bulk you need to buy to fulfill your desired amount of product (300). Simplified, you take your cars that they want, divide it by how many come in a set, and the answer will be how many sets they need to order. You need to use both the amount of desired cars and number of cars in a set as you primary information to solve this problem. Hope this helped!
Answer:
closed circle on -9 and shaded to the right
Step-by-step explanation:
Since it has "≥", the circle would be closed.
Now, it states that "x is greater than or equal to -9"
So that means x would be positive and would start at -9.
Since x is unknown, the line would extend to the right side(positive side).
