X=8
since DE is the mid segment, it connects the midpoints of the two sides. meaning that the length would be equal on both sides.
I’m going to say the top one it seems like that would be correct
Slope = (y2 - y1) / (x2 - x1)
slope = (5 + 7)/(10 - 4) = 12/6 = 2
point slope form:
y - y1 = m(x - 1)
in this case:
If you use point (4,-7) then equation will be:
y -(- 7) = 2(x - 4)
y + 7 = 2(x - 4)
If you use point (10,5) then equation will be:
y - 5 = 2(x - 10)
Answer:
B. y - 5 = 2(x - 10)
Answer: 1.5 meters
Step-by-step explanation:
Given: A lake near the Arctic Circle is covered by a sheet of ice during the cold winter months. S
S(t) models the ice sheet's thickness (in meters) as a function of time t (in weeks)
if we put x=0, then
So 4 meters is the initial thickness
To find the thickness after 6 weeks, put x=6 we get
Decrease in thickness every 6 weeks=
