Question

assuming x doesn't equal 0 and y doesnt equal 0 what is the quotient of 8x^9y^3+2x^6y^2+8x^3y over 2x^3y


please help me!

Answer 1

Take the gcf out of the numerator and reduce

Answer 2

ohhh ok thanks!

Answer 3

wait im still confused

Answer 4

willing to help?

Answer 5

I really need help this one and another one!

Answer 6

well start by rewriting the fraction

\[\frac{8x^9y^3}{2xy^3} +\frac{2x^6y^2}{2xy^3}+\frac{8xy^3}{2xy^3}\]

Answer 7

ok I get it so far

Answer 8

then start with numbers

simplify the numbers

then use the index law for division

\[\frac{x^a}{x^b} = x^{a -b}\]

and you'll get the quotient

Answer 9

would the answer be 4x^27y^3+x^18y^2+4x^9y?

Answer 11

thank you for showing your work robtobey its going to help me when I study! you guys where a big help :) have a really good day!

Answer 12

well the numbers are correct...

letter are correct but the powers aren't

looking at the first fraction its

\[\frac{8x^9y^3}{2xy^3} = 4x^{9 -1}y^{3-3} = 4x^8y^0 = 4x^8\]

does this make sense

Answer 13

can you help me with another one?

Answer 14

I have 2 questions I need help with:

1) what is the slope of a line that passes through the point (-1,1) and is parallel to a like that passes through (4,6) and (-1,-4)

2) Blake has a total of 64 DVD's and CD's. If the number of the CD's is 8 more times the number of DVDs how many DVD's does he have?

Answer 15

@campbell_st

If it was revealed that the Numerator terms are in reverse order, would the solution then be correct?

Mathematica reverses expression terms, not to confuse the user, but because that is the way they chose to code the program.

They have a function to "make it look right", called TraditionalForm.

Answer 16

ok... im confused what do you mean by that..i need help on those 2 problems I typed earlier
