Subtract (5y3 + 6y + 3y4) from (4y4 - 8y3).

A) y4 - 13y3 - 6y
B) y4 - 13y3 + 6y
C) 9y4 -13y3 - 6y
D) y4 + 13y 3 - 6y

A) y ^4 −  13 y^ 3  −  6 y

Step-by-step explanation:

     4y^4 - 8y^3

-    5y^3 + 6y + 3y^4

flip the equations around

  -8y^3 + 4y^4

-   5y^3 + 6y + 3y^4

-13y^3 - 6y + y^4

Rearrange to get:

y^4 - 13y^3 - 6y

I hope this helps you out!!!

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
