How many terms are in the binomial expansion of (3x 5)9?

 The number of terms in the binomial expansion of is 10.

Step-by-step explanation:  We are given to find the number of terms in the following binomial expansion:

We know that

the number of terms in the binomial expansion of is given by

In the given binomial expansion (i), we have

Therefore, the number of terms in the given binomial expansion will be

Thus, there are 10 terms in the binomial expansion of

i think c. but don't trust it.

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
