1686+ 754
= 2440
Answer:
A
Step-by-step explanation:
y = 180 - 100 - 38 (angle sum of triangle is 180 degrees)
= 42 degrees
x = 38 degrees (alternate angles on || lines)
z = 100 degrees (opposite angles on parallelogram are equal)
Answer:a for 1 and c for 2
Step-by-step explanation:
We are given that:
x is the age, and
y is the heart rate
It is also given that 
Now, we have been given that the person’s theoretical maximum heart rate (in heartbeats per minute) is
where x is the person’s age in years.
Therefore, 50% of
is 
Likewise, 75% of
is 
Which is the same as The system of linear inequalities that describes the given information is y>120-1/2x (for 50% max heart rate) and y<165-3/4x (for 75%).
Thus, y will lie between these two extremes as:

The graph of the same is attached.
