Step-by-step explanation:
subject arts and architecture what primary
Step-by-step explanation:
y=2x+9
y=6−x
(y-2x=9)(-1)
y+x=6
-y+2x=-9
y+x=6
3x=-3
x=-3/3=-1
sub x=-1 in eq 1
y-2(-1)=9
y+2=9
y=9-2=5
so (-1;5) is the only solution for this system
(hope it's correct)
Answer:
A. The median of the data values is 16.
Step-by-step explanation:
Answer:
2x • (x^3y^3 + 2)
Step-by-step explanation:
4x + (2x3y • y) • x) • y)
Pulling out like terms :
3.1 Pull out like factors :
2x4y3 + 4x = 2x • (x3y3 + 2)
Trying to factor as a Sum of Cubes :
3.2 Factoring: x3y3 + 2
Theory : A sum 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 : 2 is not a cube !!
Ruling : Binomial can not be factored as the difference of two perfect cube
Final result :
2x • (x^3y^3 + 2)
