A number (we will call X) times 8 Is 8x
Car: distancec = 105 km + (90 km/hr)(3 hrs)
Cycle: distancem = ratem(3 hrs)
Equate these 2 distances: 105 km + 270 km = ratem(3 hrs)
Then 375 km / 3 hrs = ratem = 125 km/hr (average speed of the motorcyclist)
24=3r/4
multiply 4 on both sides
96=3r
divide 3r and 96 by 3
r=32
Answer:
Does not have any real roots.
Step-by-step explanation:
Fully expand: x^4 - 10x^3 + 35x^2 - 50x +28
Does not have any integer roots.
Does not have any real roots.
No solutions
Set equations equal to each other
-3.5x - 3.5 = -3.5x + 3.5
The -3.5x on both sides of the equation cancels out, leaving
-3.5 = 3.5
But -3.5 does NOT equal 3.5, so the solution to the system of equations is false. This means that there are no solutions.
