The total cost for plumber number 1 expressed as a function of x is
c1(x)=45x+90
That is, the charge per hour times the number of hours plus the fixed charge for a visit.
Using the same pattern, write the function for the second plumber. Then set the two functions equal to each other and solve for
You would spend 25 minutes on the elliptical trainer, and 15 minutes on the stationary bike.
Answer: 8.4
Step-by-step explanation:
Now use the pythagoream's theorem.
![c^2=a^2+b^2\\c=\sqrt[]{a^2+b^2}\\c=\sqrt[]{(6.8)^2+(4.2)^2}\\ c=\sqrt[]{46.24+17.64}\\c=\sqrt[]{63.88}\\ c=7.99\\c=8](https://tex.z-dn.net/?f=c%5E2%3Da%5E2%2Bb%5E2%5C%5Cc%3D%5Csqrt%5B%5D%7Ba%5E2%2Bb%5E2%7D%5C%5Cc%3D%5Csqrt%5B%5D%7B%286.8%29%5E2%2B%284.2%29%5E2%7D%5C%5C%20c%3D%5Csqrt%5B%5D%7B46.24%2B17.64%7D%5C%5Cc%3D%5Csqrt%5B%5D%7B63.88%7D%5C%5C%20c%3D7.99%5C%5Cc%3D8)
