The signs of the numbers in the problem matter because if a number is negative in the equation than you're answer could be negative.  ex. -3/9= -3   but if the negative sign wasn't there than the answer would be wrong bc the answer would be positive.



hope thats what you need hope it helps.

<h3>Answer:   -10</h3>

=================================================

Work Shown:

First we need to evaluate f(3)

f(x) = -x^2 + 2x

f(x) = -(x)^2 + 2(x)

f(3) = -(3)^2 + 2(3) ... replace every x with 3; apply PEMDAS to simplify

f(3) = -9 + 6

f(3) = -3

Then we subtract 7 from both sides

f(3) - 7 = -3 - 7

f(3) - 7 = -10

The rate of each train of the northbound train traveled 10 miles per hour faster than the southbound train 26 miles per hour.

<h3>what is speed?</h3>

Speed is the time rate at which an object is moving along a path

Let the speed of southbound train is x miles/hour

so, northbound train has speed of x+10 miles/hour.

then, Speed of both train = Total distance/ total time

(x+10+x)=210/5

2x+10= 210/5

2x+10= 42

2x= 32

x= 16 miles per hour (southbound train)

northbound train:  16+10=26 miles per hour
