Which ordered pair (m, n) is a solution to the given system of linear equations?

LuckyWell [14K]

Answer:

Option (c) is correct.

The ordered pair (-4, -1) is a solution to the given system of linear equations.

Step-by-step explanation:

given : system of linear equations.

6m - 5n = 14

2m + 2n = - 10

We have to find the solution to the given system of linear equations.

Consider the given system of linear equations.

6m - 5n = 14 ......(1)

2m + 2n = - 10 .......(2)

We solve the given system using elimination method,

multiply equation (2) by 3 , we have,

(2) ⇒ 6m + 6n = - 30 ..............(3)

Subtract equation (1) and (3) we have,

6m + 6n - (6m - 5n) = - 30 -14

Simplify, we have,

6n + 5n = - 44

11n = - 44

n = - 4

Put n = -4 in (1) , we have,

6m - 5n = 14 ⇒ 6m - 5(-4) = 14 ⇒ 6m = 14 -20 ⇒ 6m = -6 ⇒ m = -1

Thus, the ordered pair (-4, -1) is a solution to the given system of linear equations.

Find the solutions of the quadratic equation

Illusion [34]

Answer:

x = $\frac{-3}{2} +- \frac{i*\sqrt{123}}{6}$

Step-by-step explanation:

x equals -b plus or minus square b squared minus 4 ac all over two a. Sing the song.

3x^2 + 9x + 17 = 0

a = 3

b = 9

c = 17

x = $\frac{-9 +- \sqrt{9^{2}-4*(3)*(17)}}{2*3}$

x = $\frac{-9 +- \sqrt{81-204}}{6}$

x = $\frac{-3}{2} +- \frac{\sqrt{-123}}{6}$

x = $\frac{-3}{2} +- \frac{i*\sqrt{123}}{6}$
