Answer:

see image

Step-by-step explanation:

To make an arrow diagram, you put an oval for the input (it also may say x) and another oval for the output (it might say y or f(x)) If there are repeated numbers you don't have to write the numbers more than once. Then you show which pairs go together with an arrow that goes from the input to the output. See image.

In order to be a function, every input can only have ONE output. So inputs can repeat BUT they CANNOT have two different outputs. Different inputs MAY have the same output.

Relation P is the function. Relation Q is NOT a function.

Which statement is true about the polynomial after it has been simplified. -10m^4n^3+8m^2n^6-6m^2n^6

laila [671]

Answer: 2m^2n^3 x ( -5m^2 + 4n^2 -3n^2 )

Step-by-step explanation:

ok, so just let me, uh, make this a little easier on my eyes lol:

-10m^4n^3+8m^2n^6-6m^2n^6 ----> (-10m^4)(n^3) + (8m^2)(n^6) - (6m^2)(n^6)

I just put in parentheses. nothing changed. just parentheses.

Since the leading coefficients, -10 , 8 , and 6 are multiples of two,

we can take out 2 from each... [-10/2 = 5 , 8/2 = 4 , 6/2 = 3 ]

= 2 x [ (-5m^4)(n^3) + (4m^2)(n^6) - (3m^2)(n^6) ]

Looking at it now...

we can take out m^2 from each... m^4 , m^2 , and m^2

m^2 [m^2 , 1 , 1]

since m^4 /m^2 = m^2 , m^2 /m^2 = 1 , m^2 /m^2 = 1

= 2(m^2) x [ (-5m^2)(n^3) + (4x1)(n^6) - (3x1)(n^6) ]

= 2(m^2) x [ (-5m^2)(n^3) + (4)(n^6) - (3)(n^6) ]

Finally, one more step...

we can take out n^3 from each term.... n^3 , n^6 , and n^6

n^3 [1 , n^2 , n^2] since n^3 /n^3 = 1 , n^6 /n^3 = n^2 , n^6 /n^3 = n^2

= 2(m^2)(n^3) [ (-5m^2)(1) + (4)(n^2) - (3)(n^2) ]

= 2m^2n^3 x [ (-5m^2) + (4n^2) - (3n^2) ]

= 2m^2n^3 x ( -5m^2 + 4n^2 -3n^2 )

ANSWER: 2m^2n^3 x ( -5m^2 + 4n^2 -3n^2 )

keep this parentheses. seriously.
