Answer:
The first 4 guests can arrive in 32,760 ways.
Step-by-step explanation:
The order in which the guests arrive is important. For example, A,B,C,D is a different outcome to B,A,C,D. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
4 guests from a set of 15. So
The first 4 guests can arrive in 32,760 ways.
I believe it's 9x2-12x+4 but I'm not quite sure cause we haven't yet gone over this in class.
My friend also believes it is this (she's in a higher level math grade than me). I'm so sorry this isn't more helpful.
Answer:
35 seconds
Step-by-step explanation:

Answer:
45 mins for two small hoses and 15 mins for two large ones
Step-by-step explanation:
Answer:
The correct answer is the first one of your list of options:
"<em>Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points</em>."
Step-by-step explanation:
Since the y-intercept is -6, then the point (0, -6) is a point on the line.That is x = 0 and y = -6. From there you move according to the slope value "2 = 2/1" which means two units of rise when the run is one.
Then, from (0, -6) move up 2 units and then right one unit. The new point should also be a point on the line. Join the two points with a line to graph the function.
