given that f(x) = 6x +1, find (f ).
(f )
| (simplify your answer.)

(f of)(-2) = -65

Step-by-step explanation:

Set up (f of)(-2)

(f o f)(-2) = f(f(-2))

Once you get (fof)(-2) you then have f(#)

f(6(-2) + 1) = f(-11)

6(-11) + 1 = -66 + 1 = -65

3.6 qt. and 2.4 qt respectively

Step-by-step explanation:

Let x be x% of 50% saline solution. And (100-x%) be the percentage of 60% saline solution.

54=x*(50/100)+(100-x)*(60/100), solving it we will get x=60%. So we need 3.6 qt. of 50% saline solution and 2.4 qt. of 60% saline solution
