The variables x and y are directly proportional, and y =4 when x=3. what is the value of y when x=15

would y be 16??

Step-by-step explanation:

If they are proportional and y = 4 when x = 3, y is 1 more than x. So when x = 15, plus one, y would equal 16

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.
