7.(i) Express 5x^2-15x+1 in the form p(x+q)^2+r, where p, q and r are constants. (ii)Hence state the least value of x^2-15x+1 and the value of x at which this occurs.

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

i believe that the answer is

b. y-1=-2(x-4)

hope this !
