Answer:
The answer is (3x^2-2x+5)
Speed is the magnitude in a velocity. It is a scalar quantity so it does not have direction unlike velocity which is a vector quantity. Speed and velocity refers to the distance traveled by a moving object per unit of time. We calculate speed as follows:
Speed = distance / time = 84 miles / 2 hours
Speed = 42 miles per hour
Step-by-step explanation:
Solve the system via elimination (add the equations):
-10y + 9x = -9
+ (10y + 5x = -5)
-----------------------
14x = -14
x = -1
Plug in the value for 'x' into the second equation:
-10y + 5(-1) = -5
Solve for y:
-10y - 5 = -5
--> -10y = 0
--> y = 0
x = -1
y = 0
If the rounding is to the nearest ten, then the greatest one
is 67,404 and the smallest one is 67,395 .
If the rounding is to the nearest hundred, then the greatest one
is 67,449 and the smallest one is 67,950 .
Answer:
x=11
Step-by-step explanation:
You have to isolate the x term; to do this you subtract 13 from the x+13 and the 24. By subtracting 13 from 13, it cancels out the 13 and 24-13=11
