Answer:
No real solutions!!! That is the answer.
Step-by-step explanation:
That'd be a total of 6 km east and 4 km north.
The distance traveled from Carol's starting point, along the path described, is
1 km + 4 km + 5 km = 10 km.
However, if you want the straight line distance from starting to end point, that would be found using the Pyth. Thm.:
sqrt [ (6 km)^2 + (4 km)^2 ] = sqrt(52) = 2sqrt(13) km
Answer: -4x(4x - 15)
Step-by-step explanation:
f(x) = 
+ 60x
y = + 60x
=> - (
- 60x)
=> -4x(4x - 15)
The line goes 3 right for every 1 down, so the gradient is -1/3
The y-intercept is +4, so the equation is actually y=-1/3x+4, so Chris is wrong.
