Solve each of the following systems. express solution sets of dependent systems in parametric form. 3x + 2y - z = 2x - y + 2z = -2x + 5y - 3z = 0 9 (b) x + y - 2z + w x + 2 + 3w -x + 2y - 2 + 11w = -2 = 3 = 5

0 is its x and y coordinate

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

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.
