Answer:
Chucks spent 8 minutes running and 15 minutes swimming
Step-by-step explanation:
Here, we want to know the amount of time Chuck spends on individual activities.
since the total time spent for the burning is 23 minutes;
then ;
r + w = 23 ••••••••(i)
Now, the number of calories burnt to running for r minutes will be r * 35 = 35w calories
The number of calories burnt to swimming for w minutes will be w * 30 = 30w calories
The addition of both gives the total calories burnt;
Hence;
35r + 30w = 730 ••••••••(ii)
So we have two equations to solve simultaneously ;
From i; r = 23-w
Substitute this into ii
35(23-w) + 30w = 730
805 -35w + 30w = 730
35w -30w = 805-730
5w = 75
w = 75/5
w = 15 minutes
but r = 23 - w
r = 23 -15
r = 8 minutes
Answer is 73 because blah blah blah blah
The domain of the function is the complete set of possible values of the independent variable. (−∞,∞),{x|x ∈ R}
<h3>What is the domain function?</h3>
The domain is the set of values for which the given function is defined.
The given function;
f(x) = 2x + 5
The domain of the given function is all real numbers except where the function is undefined.
In this case, there is no real number that makes the function undefined.
The domain of the function is the complete set of possible values of the independent variable.
(−∞,∞),{x|x ∈ R}
The range is the set of all valid y values.
