The lines shown in the figure below are A. parallel
B. Perpendicular
C. Neither parallel nor perpendicular
D. Both parallel and perpendicular

A. Parallel

Step-by-step explanation:

Parallel lines are two lines that never intersect and will never intersect. In equations, this will mean the slopes will be the same while the y-intersect is different. They are not perpendicular because perpendicular lines will intersect at a right angle, and these lines never intersect.

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.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
