What does it mean if your inference is valid?

Step-by-step explanation:

An inference is valid if and only if it is either deductively valid or inductively valid. An inference is deductively valid if and only if it is logically impossible for its premise-set to be true and its conclusion(s) false [i.e. ~ (P & ~C )].

do you mean add both of the equations together

because if you do the answer is 10x-5

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.
