Py+qy=-4y+8 what is the solution for y

y =

Step-by-step explanation:

Given

Py + qy = - 4y + 8 ← collect terms in y to the same side

Add 4y to both sides

Py + qy + 4y = 8 ← factor out y from each term on the left

y(P + q + 4) = 8 ← divide both sides by P + q + 4

y =

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
