If m + n = 7 and 2n - 3m = 6, what is the value of 3n - 2m ?

S_A_V [24]

Since m + n = 7 we know m = 7-n. So now we have 2n - 3(7-n) = 6. From this we get n = -3. So now we know m - 3 = 7 so m = 10. So now we have 3(-3) + 2(10) = ? and this comes out as 11

Answer:

x = - 9 , 6

Step-by-step explanation:

The given function is

$h(x) = \frac{x - 8}{x^{2} + 3x - 54}$

⇒ $h(x) = \frac{x - 8}{(x - 6)(x + 9)}$

Therefore, the value of h(x) will be undefined for the denominator equal to zero.

So, (x + 9)(x - 6) = 0

⇒ x = - 9 and x = 6

Therefore, the values of x which are not in domain of function h(x) are x = - 9 , 6. (Answer)
