Step-by-step explanation:
Answer: The correct answer is the third choice.
Step-by-step explanation: The question is asking you to look at pieces of data from the graph. The best way to do this question is to look at each question to determine whether the statement is true or false.
In looking at the each choice:
First one - The statement is true. Looking at the graph, a 40 and 50 year old person has the same average rate.
Second - The statement is true. Looking at the graph, you can see a steady decline from a 10 year old to a 20 year old person.
Third - The statement is false. A 10 year old and 20 year old do not have the same rate.
Fourth - The statement is true. A 20 and 30 year old have the same heart rate.

Answer:x = 1
y = 1
Step-by-step explanation:
The given system of simultaneous equations is expressed as
3x - 5y = - 2 - - - - - - - - - - - - 1
2x + y = 3 - - - - - - - - - - - - - 2
The first step is to decide on which variable to eliminate. Let us eliminate x. Then we would multiply both rows by numbers which would make the coefficients of x to be equal in both rows.
Multiplying equation 1 by 2 and equation 2 by 3, it becomes
6x - 10y = - 4
6x + 3y = 9
Subtracting, it becomes
- 13y = - 13
y = - 13/- 13 = 1
The next step is to substitute y = 1 into any of the equations to determine x.
Substituting y = 1 into equation 2, it becomes
2x + 1 = 3
2x = 3 - 1 = 2
x = 2/2 = 1
