Answer:
x ≥ -2 will have a closed circle on -2 and will be shaded to the right
Step-by-step explanation:
First you will need to determine what circle to use
- An open circle represents <em>greater than (>) </em>or<em> less than (<)</em>
- A closed circle represents <em>greater than or equal to (≥) </em>or<em> less than or equal to (≤)</em>
Here our sign in x ≥ -2 is ≥ so we will need to use a closed circle
Then to determine which way you shade, just follow the direction that the inequality sign is "pointing"
- x ≥ -2 will have a closed circle on -2 and will be shaded to the right

50 = x^2
To isolate x you need to do the opposite of an exponent, which would be square root.
= x
That is the exact form, in other words your answer, if teacher is looking for a decimal, it would be
7.07 = x
