What is the additive inverse of the polynomial –9xy2 + 6x2y – 5x3? a) –9xy2 – 6x2y + 5x3 b) –9xy2 – 6x2y – 5x3 c) 9xy2 + 6x2y + 5x3 d) 9xy2 – 6x2y + 5x3

The correct answer is option d)  9xy2 – 6x2y + 5x3

Step-by-step explanation:

The additive inverse of a number x  is -x

Here the polynomial is –9xy2 + 6x2y – 5x3

To find additive inverse of polynomial

Additive inverse of –9xy2 + 6x2y – 5x3 is -(–9xy2 + 6x2y – 5x3)

-(–9xy2 + 6x2y – 5x3) = -(-–9xy2) - 6x2y –(- 5x3)

  = 9xy2 - 6x2y + 5x3

Therefore the correct answer is option d)  9xy2 – 6x2y + 5x3

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
