A possible coordinate could be 4.....
Lucas equation for his location is x(t) = 13t.
Alfonso's equation is x(t) = 238 - 21t
If you equate these, you get:
13t = 238 - 21t =>
34t = 238
t = 7
So after seven hours they meet.
Answer:

Step-by-step explanation:
we would like to integrate the following Integral:

well, to get the constant we can consider the following Integration rule:

therefore,

recall exponent integration rule:

so let,
Thus integrate:

simplify addition:

reduce fraction:

finally we of course have to add the constant of integration:

hence,
our answer is D)
The slope of the line is 1.
The slope of the line is 1 because the line moves ror goes up from left to right, making it a positive. The line also moves one block over and one block up.
