(perform the indicated operation to write given polynomial in standard form: x+ 1) − (x − 2) − (x +3)

So the standard form of the equation is -x      

Step-by-step explanation:

We have given polynomial

We have to write the polynomial in standard form

For writing in standard form we have to to first operation on the function

Which is subtraction in given question

So

So the standard form of the equation is -x

i am sure it will be 90 degrees.

step-by-step explanation:

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
