So if we're talking about l = prt. (Principle, rate, time) what do they mean if they say replace letters w into numbers?

answer: 7

step-by-step explanation: cause i checked it

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.

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
