(x - 4)(x + 2)

x^2 + 2x - 4x - 8

x^2 - 2x - 8

Let y = x^2 - 2x - 8

It is a parabola.

Take it from here.

Find the equation of the linear function represented by the table below in the slope-intercept form.

MAXImum [283]

Answer:

y=x-32

Step-by-step explanation:

y=mx+b where m is the slope and b is the y-intercept.

slope=change in y/change in x

=5/5

y=5x+b --> choose a random point

(7,3) ---> 3=5(7)+b=35+b

b= -32

y=x-32

The pyramid shown has a square base that is 18 inches on each side. It has a surface area of 864 square inches. What is the slan

disa [49]

The first step is to find the relationship between the square base and the surface area.

Surface area (SA) = area of the square (SS) + area of triangles.4(AT)

Thus we can conclude area of triangles 4(AT) = SA - SS = 864 - (18*18)

4(AT) = 864 - 324 = 540

Each triangle = 540/4 = 135 square in.

An area of one triangle (AT)= (base* slant height)/2

The base = 18 in.

slant height = 2(AT)/base = 2(135)/18 = 15
