Gilda walks to the train station. If she walks at the rate of 3 mph, she misses her train by 7 minutes. However, if she walks at
lorasvet [3.4K]
We'll represent the distance as d and the time as t. 
d= 3(t+7)            because Gilda is 7 minutes late when travelling 3 mph
d= 4(t-5)             because Gilda is 5 minutes early at 4 mph

d= 3t + 21
d= 4t -20
3t +21 =4t -20
41=t
d= 3(41) +21= 144
The distance is 144 miles.

Think about the function f(x) = 3 - 2x
Angelina_Jolie [31]

f(0) means the function output when the input is x = 0. This is the same as saying the y value when x = 0.

f(x) = 3-2x

f(0) = 3-2(0)

f(0) = 3

The point (0,3) is on the graph. This is the y intercept which is where the graph crosses the y axis. The y intercept always occurs when x = 0.

So in other words, the special name for f(0) is the y intercept.
