Step-by-step explanation:
f(x) = g(x)
-3x + 4 = 2
4 - 2 = 3x
2/3 = x
Since Emily is walking at a constant speed, we can solve this using proportions, equating ratios of distance/time.
The first ratio is 3/4 miles/1/4 hour
The second ratio is 1 mile/ x hour
Equating the two ratios: 3/4 / 1/4 = 1/x
3 = 1/x
x = 1/3 hour
Simplify by dividing the two by 14
