Answer:

3x+2y=-3

Step-by-step explanation:

Slope = -3.000/2.000 = -1.500

x-intercept = -3/3 = -1

y-intercept = -3/2 = -1.50000

2x-3y=-15

Slope = 1.333/2.000 = 0.667

x-intercept = -15/2 = -7.50000

y-intercept = 15/3 = 5

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 $(-4)^{11}$ .
