Subtract 7x-9from 2x^2-11

2X^2 - 7x - 2

Step-by-step explanation:

Subtract 7x-9from 2x^2-11

the 9 will be added to the -11

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.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
