This is a quadratic equation, which is also a polynomial. Polynomials all have the domain (-infinity, +infinity).
As for the range: You can see from the graph that the smallest y-value is -2. Thus, the range is [-2, infinity).
Answer:
x < -8
Step-by-step explanation:
-x - 10 > 14 + 2x
Subtract 2x from both sides;
-3x - 10 > 14
Add 10 to both sides;
-3x > 24
Divide both sides by -3
The sign switches when divide by a negative number.
x < -8
It would take (2 hours and 45 min) for the train to travel this far
Hope this helps.
Answer:
Step-by-step explanation:
The opposite of a number is found by taking the opposite sign of the one given. The opposite of 3 is -3; the opposite of -2 is 2.
Therefore, the opposite of -5.5 (point P) is 5.5 (point S).
