<em>The </em><em>evaluated expression </em><em>needed is </em>
<em>or </em>3
The expression that needs to be evaluated is
1 
+ 3
for x = 
We are being asked here to solve the mathematical equation by substituting the value of x for 1/4. If we go ahead and do the substitution we have;
1
+ 3
where x = = 0.25
this is equal to
1
+ 3 =
1 * 8/5 + 3 * 2/3
8/5 + 2 = 18/5 = 3

Answer:
Maximum heart rate can be represented into a function as follows
let
x = age
y = Maximum heart rate
equation will be
y =220-x
for example if we take a person who is 50 years old then the maximum heart rate that person will have will be
y= 220 - 50
y = 170
This means that this is the average maximum number of times your heart should beat per minute while exercising.
