Remember, for |a|=b, assume and solve a=b and a=-b
so
first get into |a|=b form
-3|x-3|=-6
divide both sides by -3
|x-3|=2
so solve
x-3=2 and x-3=-2
add 3 to both sides
x=5 and x=1
the solutionsa re x=1 and 5
F(x) = 0.6x + 13...this is part A (or could be written as y = 0.6x + 13)
1 meter = 100 cm....so 0.208 meters = (0.208*100) = 20.8 cm
20.8 = 0.6x + 13
20.8 - 13 = 0.6x
7.8 = 0.6x
7.8/0.6 = x
13 = x.....so for part B, ur answer is 13 days
