S. o.s ! identify the slope and y-intercept 1.) y = 2x - 8 2.) y = -1/2x + 7 3.) y = 1/4x - 3/4 4.) y = 5x + 12

1.) Slope=(2)  Y-int (-8)

2.) Slope = (-.5)  Y-int (7)

3.) Slope = (1/4)   Y-int (-3/4)

4.) Slope = (5)     Y-int (12)

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
