The math department purchases a photocopier for $4,500. Write an equation (in y=mx+b form) to model the value of the photocopier, y, in x years if the copier's value depreciates at a constant rate of $400 per year.

table 1

step-by-step explanation:

1-16

2-32

4-64

8-128

all multiples of 16

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
