First simplify the equation.
3x+3y= -x+5y
4x=2y
2x=y
y=2x
Means that the y value is 2 times the x value.
answer: C but there are more solutions than just (1,2) and (2,4)
72 is a number that can divide into 8 and by 9 also
Independent variable - It is a variable that stands alone and isn't changed by the other variables you are trying to measure.
for example, someone's age might be an independent variable. other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age.
dependent variable - It is something that depends on other factors.
for example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.
Answer:
The offices can be filled in 4080 ways.
Step-by-step explanation:
This question can simply be solved by permutations.
For the first office there are 17 people available, for the second office 16 people are available, and for the third office 15 people are available.
17x16x15 = 4080 ways.
It can be also thought in a simpler way by thinking that we are to make a combination of 3 people from 17 people and those 3 people can further be ordered into 3! ways. So the number of ways are:
3! x 17C3 = 17P3 = 4080 ways
