The equation for those points is:
y = -1/2x + 5/2
Smaller leg = x
longer leg = y
hypotenuse = z
y=x+7
z=x+8
due to
but x cannot be -3
so smaller leg is 5 inches
then longer leg = 5+7 = 12 inches
and hypotenuse = 5+8 = 13 inches
Based on the given situation above, the given values are 8 kilometers and 24 minutes. To simplify these values, we will come up with the result of 1 km in 3 minutes. Therefore, the winner of the New York marathon ran 0.33 kms per one minute so the runners unit rate is 0.33kms/minute.

Step-by-step explanation:
Answer:
BE = 3 in; EF = 2 in; FC = 3 in
Step-by-step explanation:
∠EAD ≅ ∠AEB ≅ ∠EAB so ΔABE is isosceles and AB ≅ BE = 3 in.
Likewise, ∠FDC ≅ ∠FDA ≅ ∠DFC, so ΔDCF is isosceles and AB ≅ BC ≅ FC = 3 in.
Then EF = 8 in - 3in - 3 in = 2 in
