Answer:

The 30 pound bag of bird food

Step-by-step explanation:

19.50 divided by 25 = 0.78 cents a pound

22.80 divided by 30 = 0.76 cents a pound

Therefore, 0.76 cents is cheaper :)

Answer:

The vertex or top is ( 2, -9)

Step-by-step explanation:

Given y = (x - 5 ) * ( x + 1 )

x² - 4x - 5

See attachment.

The vertex of the parabola is the Top.

The vertex of a parabola is the point where the parabola crosses its axis of symmetry.

If the coefficient of the x² term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the “ U ”-shape. If the coefficient of the x² term is negative, the vertex will be the highest point on the graph, the point at the top of the “ U ”-shape.

The standard equation of a parabola is it

y = ax² + bx + c.

But the equation for a parabola can also be written in "vertex form": y = a(x−h)² + k

In this equation, the vertex of the parabola is the point (h,k) = (2, -9)
