137.5 I took the test and got 100%
Answer:
y=9/2x+2
Step-by-step explanation:
Comparing map distance to real distance we get 2cm/4km. That means 1cm = 2km.
So the map distance is half the real distance (well, technically not as one is in cm and the other in km but it’s enough to think this way) and a real distance of 10km must mean a map distance of half that (again ignoring the units) so we get 5cm.
Answer:
Step-by-step explanation:
f(x) = x²-2
g(x) = 4x-2
f.g(x)= x²-2(4x-2) = x²(4x-2)-2(4x-2) = 4x³-2x²-8x+4
f.g(x) = 4x³-2x²-8x+4
