Reorder both sides

3y-6x=9
7-4y-3x=9

Multiply both sides
-6x-3y=9
6x+8y=-4

Dived both sides

11y= 5

Y=5/11

Substitute the value of Y

-3x-4(5/11)

Equals —> -14/11

Answer : (5/11 , -14/11)

Express the following in exponential notation: (-4) x ... x (-4) 11 times

Anni [7]

Given:

The expression is:

$(-4)\times ...\times (-4) (11\text{ times})$

To find:

The exponential notation for the given expression.

Solution:

We know that

$a\times a\times ...\times a(n\text{ times})=a^n$ ...(i)

We have,

$(-4)\times ...\times (-4) (11\text{ times})$

Using (i), the given expression can be written as:

$(-4)\times ...\times (-4) (11\text{ times})=(-4)^{11}$

Therefore, the exponential notation of the given expression is $(-4)^{11}$ .
