Answer:
The answer is
Step-by-step explanation:
Solution:
Let we first name the Triangle as Δ ABC and ray BD as a bisector of ∠B
as shown in the figure below.
As ray BD is the bisector of angle B so, by Angle bisector theorem property we have
∴
∴
∴
∴ final answer
987164 is in the ones place
3 is in the tens
0 is in the hundreds
2 is in the thousands
Well, do algebra first. So, x+2/X+2 wouldn't that cancel out to 1.... So f(x) = 1 and no need for a calculator!
Hope this helps!
The independent quantity is the average class size and the dependent quantity is the cost ⇒ c
Step-by-step explanation:
Lets revise the meaning of dependent and independent variables
- The dependent variable is the one that depends on the value of some other number
- The dependent variable is the output value and the independent variable is the input value
- Ex: if y = 2x + 3, x is the input and y is the out put, then is independent variable and y is dependent variable
∵ The cost of the textbook increases with the average class size
- The cost of the textbooks depends on the average of the
class size
∴ The input is the average class size
∴ The output is the cost of the textbooks
∵ The input variable is independent variable
∵ The output variable is dependent variable
∴ The average of the class size is independent
∴ The cost of the textbooks is dependent
The independent quantity is the average class size and the dependent quantity is the cost
