Answer:
-13v^4 + v^3 - 10v (if simplified)
Step-by-step explanation:
combine like terms
(-7v^4 - 5v) - (-5v^3 - 2v)+ ( - 7v - 6v^4 - 4v^3)
-7v^4 + -6v^4 = -13v^4
-5v^3 + -4v^3 = v^3 (the five becomes positive because of the negative sign infront of the parenthesis) Example: -(-5v^3) = +5v^3
-13v^4 + v^3 -5v -(-2v) -7v (now we have the -2 left alone in the parenthesis which means it becomes positive too) Example: -(-2v) = +2v
-5v +2v - 7v = -3v -7v = -10v
Answer: -13v^4 + v^3 - 10v
A:
An independent variable could be how long she works. (Well it's not really independent I guess... Sorta depends.)
A dependent variable could be how much money she makes, depending on how long she works.
B:
Umm, like:
(1, 7)
If 1 was how many hours she worked and $7 is how much money she made, and therefore x would be how many hours she worked and y would be how much total money she made.
(2, 14)
(3, 21)
C: An equation would be 7x = y.
Answer:
4/9
Step-by-step explanation:
Let's find a greatest common denominator for 3/2, 5/6, and 2/9
GCD is 18
Change all fractions to a denominator with 18 and solve
27/18 - 15/18 - 4/18 = 27/18 - 19/18 = 8/18
8/18 can be simplified, so divide the numerator and denominator by 2
You will get 4/9
Hope this helps :)
