Answer: A: -2x^3 - 6x^2 + 9x
Step-by-step explanation:
f(x) - g(x) is a simple subtraction problem, just like 2 - 1, or 8 - 5. So, treat the functions like normal questions.
> f(x) = 3x^3 - 4x^2 + 6x
> g(x) = 5x^3 + 2x^2 - 3x
> f(x) - g(x)
Substitute these values for f(x) and g(x).
> f(x) - g(x)
> (3x^3 - 4x^2 + 6x) - (5x^3 + 2x^2 - 3x)
Now, we combine like terms*:
> For x^3: (3x^3 - 5x^3) = -2x^3
> For x^2: (-4x^2 - 2x^2) = -6x^2
> For x: (6x + 3x) = 9x
*NOTE: Remember that when there is a subtraction sign in front of a group of numbers, all the numbers inside of the parenthesis are multiplied by -1, and get their signs switched.
Putting all of these values together, we get (-2x^3 - 6x^2 + 9x).
Answer:
Step-by-step explanation:
4) 35x + 28y =7*5*x + 7*4*y = 7(5x + 4y)
5) Cost of top = $9
Cost of 3 top = 9*3 = $27
Cost of skirt = $x
Cost of 3 skirt = 3x
Cost of 3 skirt and 3 top = 3x + 27
Cost of 2 skirt = 2x (as she bought 5 skirts)
Cost of her purchase = Cost of 3skirt &3 top and 2skirt
= (3x + 27) + 2x
= 5x +27
6) Cost of 5 nail polish bottle = 5p
Cost of two lip gloss tube = 2g
Cost of one gift bag = 5p + 2g
Cost of 8 gift bag = 8* ( 5p + 2g)
=8*5p + 8*2g
= 40p + 16g
Add 1 to both sides and then split the parentheses to (x+3) and (x+3) then multiply them to get x^2+6x+9=36
Answer:
-9=-1/3-13 is it in slope intercept form, look up ones to put it in different forms
Step-by-step explanation:
So if he wants to have more then 100 in his bank then what i would do is take 100 from 460 and you get 360 then divide that by 45 and you get 8 but as said before he wants more then 100 so he would be able to pay 7 months in a row and have over 100 in his bank account still
