In the expansion of (2m-3n)^9, one of the terms contains m^3. determine the exponent of n in this term.

•2

•3

•5

•6

The correct option is 6

Step-by-step explanation:

Given expression,

By the binomial expansion,

Where,

Thus,

For finding the term containing

9 - r = 3

⇒ 9 - 3 = r

⇒ r = 6

i.e. the required term is,

Hence, the power of n in that term = 6.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

0.85% : )
