Answer:
Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.
Step-by-step explanation:
i) f(x) = -(x+9)(x-21)
ii) therefore y = f(x) = -
+ 12x + 189 = - ( - 12x +36) + 36 + 189
iii) therefore y = f(x) = - 
+ 225
iv) when x = 6 then y = 255
Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.

Answer:
6 3/4
Step-by-step explanation:
to write 54/8 into the mixed number and in the simplest form
we first simpify 54/8 which is 27/4
to convert 27/4 into a mixed number we first see how many times does 4 goes into 27 with the remainder. 4 goes into 27 6 times with the remainder of 3. 4 goes into 27 6 times so, 6 will be the whole part 3 remainder will be the numerator and 4 will be the denominator. like 6
