The number of combinations of 10 different things taken 4 at a time is:
The answer is: 210
<h3>Solution:</h3>
<h3>Answer:</h3>
The answer is option d. X = 3
all angles = 180 degrees total
add the ratios: 2 +4 +9 = 15
180/ 15 = 12
12*2 = 24
12*4 = 48
12*9 = 108
108 + 48 + 24 = 180
the three angles are: 24, 48 and 108
So A is days rented to the total cost. For B just get the slope and add 1 more point to the graph because a week is 7 days and then write (day,total cost)
Step-by-step explanation:
there are more than one way it depends what the question gives you but the easiest way is from the graph by the graph you can calculate them both for the domain you can determine it through the graph or the function by find when the function is undefined but for the range you should have the graph or drow it by the function to calculate it
