What does the 3 represent in 3(20 15)?

1 answer:

4 0

Depending on what you're supposed to do, the three could either mean to distribute it into the equation, giving you
either
(3*2015) or (3*20)*(3*15) or (3*20) +/- (3*15)

Or an example of factoring where they took 3 out of 60 and 45.

There are no instruction on what to do in this question.

$11.96/4 is 2.99

So one bag costs $2.99 and for any rest of number of bags we just multiply that number by 2.99!!

Hope this helps. :)

Calculate dy/dx when xy^3 + y =3x

Yuki888 [10]

The answer is the option D.

You have to use implicit derivative

1) dy / dx = y'

2)

$xy^3+y=3x

y^3+3xy^2y'+y'=3

(3xy^2+1)y'=3-y^3

y'= (3-y^3)/(3xy^2+1)

y'=(3-y^3)/(1+3xy^2)

10(-2)^2/-5
The solution to this would equal to -8

:) You are using substitution which is putting the number as the variable or the letter.
