Devante and Karen are 230 feet apart when they start walking toward one another. They are walking at the same speed, so whenever Devante travels some number of feet, Karen travels the same number of feet. Let x represent the number of feet Devante has traveled since he started walking toward Karen. Write an expression in terms of x that represents the number of feet Devante has walked toward Karen since they started walking

Karen (and Devante) walked x feet. They will be toguether after walking 115 feet each.

Step-by-step explanation:

I will assume that you want to know how much karen was walked towards Devante. Since they both travel at the same speed, then if Devante walks x feet, so does Karen.

SInce both of them are traveling in opposite directions, then in order for them to meet they need to walk a total of 230 feet in combination toguether. Since they travel at the same speed, then each one has to travel half that amount, hence each one will travel 230/2 = 115 feet until they meet.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
