A closed dot mean "greater than or equal to" or "less than or equal to"
An open dot means "less than" or "greater than"
In this case, an open dot would mean
X>-2
Answer: Hope this helps you
1/2
Step-by-step explanation:
<em>To find the x-int of any equation, you will need to replace the y with a 0 since when the x-int is when y is 0.</em>
8x+2y = 4 ➨ 8x+2*0 = 4
<em>Now I will do 2*0 which anything times 0 is equal to 0. And we are left with the equation of:</em>
8x = 4
<em>Now I will divide both sides by 8, which isolates our x.</em>
x = 1/2
The x-int is 1/2.
Answer and Step-by-step explanation:
If you see a number or fraction or anything we g beside it, such as:
4.2g
6g

^ That is grams
If you see anything with kg next to a number, fraction, e.t.c, such as

5kg
6.2kg
^ That is kilograms
Answer:Domain: all x-values that are to be used (independent values).
Step-by-step explanation:The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values).
