Negative four times a number decreased by nine is greater than negative thirteen

x<1

Step-by-step explanation:

Le the unknown number be x;

Negative four times a number is expressed as -4x

Negative four times a number decreased by nine is expressed as -4x - 9

If this expression is greater than negative thirteen, then;

-4x - 9  > -13

-4x - 9+9 > -13+9

-4x > -4

x < -4/-4

x < 1

Hence the required solution is x<1

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.
