Be quick, i need this as soon as possible!

6 More times!

Step-by-step explanation:

Ivan has to earn 88$. If he walks one time he makes 8$. So, to make 88$ he has to walk the dog i.e., 11 times.

Out of 11 times, he has already done it 5 times. So, he should do it 6 more times.

Therefore, the answer is 6 more times.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
