Answer:
Step-by-step explanation:
To find a function's inverse, you first switch the x and y coordinates, and then solve for the new y. The same goes for finding an inverse's function. We have:
We will switch the x and y variables and then solve for the new y:
and
11x = y + 4 so
11x - 4 = y and
11x - 4 = f(x) which is choice C.
7.83 x 10^-7 (the *^* is where the power goes)
Let g represent the number of gallons to be drained. Then the amount (in gallons) of bleach in the tank will be given by
.. 4%*(120 -g) +100%*g = 7%*120
.. 4.8 -.04g +g = 8.4
.. 0.96g = 3.6
.. g = 3.6/0.96 = 3.75
3 3/4 gallons need to be drained and replaced with 3 3/4 gallons of bleach.
