Answer:
x=-1, y=-3. (-1, -3).
Step-by-step explanation:
-6x+4y=-6
-8x+4y=-4
------------------
-6x+4y=-6
-(-8x+4y)=-(-4)
----------------------
-6x+4y=-6
8x-4y=4
--------------------
2x=-2
x=-2/2
x=-1
-8(-1)+4y=-4
8+4y=-4
4y=-4-8
4y=-12
y=-12/4
y=-3
Where's the graph at? Did you forget to place?
4/9(2n)+4/9(-3)
(4x2/9)n+(4 x -3)/9
(8/9)n -12/9
8/9n-4/3
Most of these problems are the commutative property:
Addition
a + b = b + a
Multiplication
a * b = b * a
and the associative property:
Addition
(a + b) + c = a + (b + c)
Multiplication
(a * b) * c = a * (b * c)
There's also the Identity property:
Addition \ Subtraction:
a + 0 = a \ a - 0 = a
Multiplication \ Division:
a * 1 = a \ a / 1 = a
The answer is 0. This is because of the proportion of the two
