Answer: 4
<u>Explanation:</u>
f(x) = 2x - 1
f(√2) = 2√2 - 1
f(1) = 2(1) - 1
= 2 - 1
= 1
f(√3) = 2√3 - 1

The system of equations is
Step-by-step explanation:
We can answer this question as follows.
First of all, we call:
t = number of treadmills
b = number of stationary bikes
The two conditions that we have can be translated into equations as follows:
- The gym has a total of 25 treadmills and stationary bikes:
- There are seven more stationary bikes than treadmills:
So the system of equations to solve is
We now solve it in the following way: first, we rewrite the second equation by bringing t on the left side,
Now we add the 1st equation to the 2nd equation:
And therefore,
So, there are 16 stationary bikes and 9 treadmills.
