Which function represents exponential decay? O fx) = 1/2(2)x
O fx) = 3/4(-1/5)x
Ofx) = 3(7/2)x
O f(x) = 2(2/3)x

the answer will be

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
