The answer would be 2431.
Okay first you should subtract 8.50 from 61.60 because the delivery charge doesn't count. 61.60-8.50=53.1. now divide 53.1 by 2.95. 53.1÷2.95=18. Romeo ordered 18 roses for his girlfriend.
y = (x-6)²-3
1) Let's write a transformation described as it is, algebraically speaking.
• opening upward, (a >0)
,
• shifted 6 units right, (-6)
,
• and three units down -3
2) Starting from the parent function y=x², then we can write:
y = (x-6)²-3
Notice that the horizontal shift is within the parentheses with a swapped sign. And outside that -3 indicating the vertical shift.
Answer:
B or D ( answer = 5 => Two options is one! One of the options should be 5)
Note: The width of a rectangle will never be negative.
Answer:Infinite solution
Step-by-step explanation:
For Inequalities

3y-6x>2
and 
3y-6x<1
The required Inequalities have no solution because they do not share the common region for a common solution
But if signs of both inequalities is changed then the system has infinite number of solution.

3y-6x<2
and 
3y-6x>1
