A(n)=47+(<span>n - 1)(-15) </span>
x= r - h/y subtract r from both sides
x-r = -h/y multiply each side by -y
-y(x-r) = h
-xy +yr = h
615-138 = 477 you start with 615 take away how many pens are left and then you get your answer
C) 1 b =-2. D) 7 f(-2) = 3(-8) - 2. -5 x=6
y. 4(y + 1) = x. If (x, y) is the solution to
the system of equations.
