Answer:
both are (-∞, ∞)
Step-by-step explanation:
The domain and range of any odd-degree polynomial are both "all real numbers." They go from -infinity to +infinity.
Your polynomial is of degree 3, so is of odd degree. The arrows on the ends of the curve indicate it extends to infinity in that direction.
y → +∞ for x → +∞
y → -∞ for x → -∞
For this case we must make a conversion from pounds to kilograms.
By definition we have to:
1 kg equals 2.20462 pounds. Making a rule of three we have:
2.20462 pounds ---------------> 1 kg
127 pounds -----------------------> x
Where "x" represents the amount of kg.

Thus, 127 pounds represent 57.61 kilograms.
Answer:
57.61 kilograms.
If you buy 1 container of cream and an unknown number of bagels, x will represent the number of bagels you buy.
1.29+0.75x<=7.00
I say less than or equal to because you cannot buy more than 7 dollars worth of things.
Answer:
465.988 mph
Step-by-step explanation:
The two speed vectors form two sides of a triangle. Their included angle is 45°, so the law of cosines can be used to find the resultant magnitude x.
x^2 = 500^2 +50^2 -2·500·50·cos(45°) ≈ 217,144.66
x ≈ √217,144.66 ≈ 465.988 . . . . miles per hour

You may find you need to round the answer to the nearest whole number.
The answer is B because if you make plot the the numbers on a grid as coordinates a linear function is created.
