D.
24 is the distance Carlos biked
30 is the total distance
24:30 divided by 6
4:5
A = a+b/2 x h
Add sides a and b then divide by 2
After that multiply by the h
We know that
the slope formula is
m=(y2-y1)/(x2-x1)
(x1,y1)=(0,2)
(x2,y2)=(x,0)
m=1-----> equation 1
m=(0-2)/(x-0)------> m=-2/x -----> equation 2
equate equation 1 and equation 2
1=-2/x------> multiply by x both sides------> x=-2
the point (x2,y2) is ----------> (-2,0)
