10 -4 (2x-1) = -2(3-x)

x = 2

Step-by-step explanation:

10 -4 (2x-1) = -2(3-x)

10 - 8x + 4 = -6 + 2x

-10x = -6 -10-4

-10x = -20

x = -20/-10

x = 2

2

Step-by-step explanation:

10-4(2x-1)=-2(3-x)

10+4-8x=-6+2x

14+6=8x+2x

20=10x

x=2

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

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.
