[4x -1/
(x+4) (4x² +1)]=
[a\
x+ 4]+
[bx+c\
4x² + 1]
after clearing fractions to decompose, the equation 4x - 1 =a(4x^2+1) + (bx+c)(x + 4) results. if x= -4 what is the value of a?

A = -

Step-by-step explanation:

Given: 4x - 1 = A[4x² + 1] + (Bx + c)(x + 4)

To determine the value of A, we have to eliminate the other two variables, viz, B and C.

To do this simply put x = -4.

We get:

4(-4) - 1 = A[4(-4)² + 1] + 0

⇒ -17 = A(65)

∴ A = is the answer.

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
