x^2 = 81/100
Let's take the square root of each side
x = 0.9 and -0.9
This point falls on none of your possible answers.
We can first tell that it falls neither positive or negative in terms of x since the x value is 0.
We can also tell the y term is negative. Therefore, it would fall on the negative y-axis.
X + 7 < 2x +7
therefore
<span>x < 2x
</span>x > 0
another:
25 + 7 > 10 + 7
therefore
25 > 10
