Explanation:
To find if 0 is greater than -1 we can graph these values on a number line. If 0 is to the left of -1 then is less than -1, if it's to the right, then it's greater than -1:
Answer:
Yes, 0 is greater than -1.
The solution of the system of equation is the intersection point of the two quadratic equations, so we need to equate both equations, that is,
So, by moving the term -3x^3+20 to the left hand side, we have
Then, in order to solve this equation, we can apply the quadratic formula
In our case, a=5, b=-3 and c=-30. So we get
which gives
By substituting these points into one of the functions, we have
and
Then, by rounding these numbers to the nearest tenth, we have the following points:
Therefore, the answer is the last option
