Substract by 12 from 42, and keep going down until you hit -54, which is 8 hours!
Move all terms to the left side and setequal to zero. Then set each factorequal to zero. and you should get x=9/a+b
0 and 2
f(x) = g(x) will be the input or x value at which f and g have the same output or y value. Look in the table where two numbers repeat right next to each other.
−1 −7/2 −9/2

There are two solutions to f(x) = g(x) which are x=0 and x=2.
42 hundredths as a decimal is 0.42
