Which answer includes the intrevals that contain the solution to the inequality x^2-1/3x+9&lt;0
victus00 [196]

Answer:

x<±1 and x< -3

Step-by-step explanation:

Given the inequality x^2-1/3x+9<0, we are to find the values of x that satisfies the inequality

x^2-1/3x+9<0

x^2-1/3x+9 (3x+9)²<0*  (3x+9)²

(x^2-1)(3x+9) < 0

x²-1 < 0 and 3x + 9 <0

x²-1 < 0

x²<1

x<±√1

x<±1

Also 3x + 9 <0

3x < -9

x < -9/3

x < -3

Hence the required values of x are x<±1 and x< -3

Find an equation for the line with undefined slope and passing through the point 9, -7
serg [7]

recall, slope = rise/run, and that a fraction is undefined when the denominator is 0, meaning this slope has a run = 0.

to make it short, when the slope is undefined, is a flag that we simply have a vertical line.  Check the picture below.

For the circumference, you actually multiply by 20 because of the formula πd = C [OR 2πr = C]. You meant to double the radius.
