What value must k take in order for the following expression to be greater than zero? 3/k - 5/7

It looks that 3/k must be greater than 5/7

so basically 21>5k. So k needs to be smaller than 4.2

And obviously greater than 0.

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
