1 answer:
stiv31 [10]3 years ago
6 0

Answer:

consistent independent

Step-by-step explanation:

x+y = -4     y = -x -4

y = 2x-1


The equations do not have the same slope , so they are not the same line

therefore the are not dependent

If they do not have the same slope, they cannot be parallel and cannot be inconsistent

The two lines must be consistent independent

Factored 8x2y3-5= <br> I need the answer
ANTONII [103]

Answer: Reformatting the input :

Changes made to your input should not affect the solution:

(1): "y3" was replaced by "y^3". 1 more similar replacement(s).

STEP

1

:

Equation at the end of step 1

(23x2 • y3) - 5

STEP

2

:

Trying to factor as a Difference of Cubes

2.1 Factoring: 8x2y3-5

Theory : A difference of two perfect cubes, a3 - b3 can be factored into

(a-b) • (a2 +ab +b2)

Proof : (a-b)•(a2+ab+b2) =

a3+a2b+ab2-ba2-b2a-b3 =

a3+(a2b-ba2)+(ab2-b2a)-b3 =

a3+0+0+b3 =

a3+b3

Check : 8 is the cube of 2

Check : 5 is not a cube !!

Ruling : Binomial can not be factored as the difference of two perfect cubes

Final result :

8x2y3 - 5

=> 6n = 72 
=> n = 12
The first piece is 12 and the second piece is 60.
