Whenever you are graphing an inequality,
< or > means the line is dotted
≤ or ≥ means the line is full and complete
The equation is x ≤ 3 so the answer is either A or B
x ≤ 3 means that x is less than or equal to 3, so the part that is shaded blue is supposed to be 3 and below.
The answer is A
Answer:
C. 1.15<em>x</em> because adding 15% to the cost of the haircut is the same as multiplying the cost by 1.15.
Step-by-step explanation:
This answer is correct because, adding 0.15x (or 15%) to the total amount is the same as multiplying the cost by 1.15. This is because, the 1 that is added to 0.15 represents the total, since we are just multiplying instead of adding to it.
Hope this helps! :D
