Aparabola has the equation –5x2 + 30x – y – 34 = 0. which equation is that of the parabola in vertex form

ian gone lie this got me confused

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.

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.

the answer is b to that quesiton
