Which is not the quadratic inequality?
1 answer:
Answer:
A.
Step-by-step explanation:
A quadratic inequality looks like a quadratic equation, but with signs
<, >, ≤, or ≥
instead of sign =
You are given one equation (the first one, because the sign is =) and two inequalities (the last two beacause the signs are < and > respectively).
Thus, correct option is A,
is not a quadratic inequality (it is a quadratic equation)

Answer:
in scientific notation, the expression can be written as 6.237 x 10⁶
Step-by-step explanation:
Given;
6.3×10 to the second power times 9.9×10 to the 3rd power
Using scientific notation, it can be interpreted as;
This can be simplified as;
Therefore, in scientific notation, the expression can be written as 6.237 x 10⁶
The correct graph is B.
This can be determined by one small factor. Since there is a closed circle at the end of the first graph, we know that the first graph (the x^3 - 3), must be inclusive. So we must have a next to that graph and not a <. The only one that has that with the first equation is B.
