Find the 5th term in the expansion of (x – 3y)8

Lynna [10]

Not sure what you mean by 5th term, I assume it's the term with the form x^3y^5

Then, you can use combination method:

C(8,3) * (-3)^5 = -13608

So, 5th term is -13608x^3y^5

Graph the system below 2x-3y=-18 3x+y=-5

pshichka [43]

Answer:

$x = 3 \frac{(y - 6)}{2} \\ \\ x = \frac{ - 5 - y}{3}$

Step-by-step explanation:

$2x = - 18 + 3y \\ 2x = 3y - 18 \\ x = \frac{3y - 18}{2} \\ x = \frac{3(y - 6)}{2} \\ \\ 3x = - 5 - y \\ x = \frac{ - 5 - y}{3}$

Solve the system of equations given below.

eduard

Answer:

The system of this equation is ( -1, 10) which is Option A.

Step-by-step explanation:

Solve for y in the first equation.

$y = - 5x + 5 \\ - 2y = - x - 21$

Replace all occurrences of yy with -5x+5 in each equation.

$10x - 10 = - x - 21 \\ y = - 5x + 5$

Solve for x in the first equation.

$x = - 1 \\ y = - 5x + 5$

Replace all occurrences of x with -1 in each equation.

$y = 10 \\ x = - 1$

The solution to the system is the complete set of ordered pairs that are valid solutions.

(−1, 10)

Hence, the system of this equation is (-1, 10). 

Option A.
