In this item, we are given with the equation,
y = 1200 + 400x
where y is the total amount of rent and x is the number of months.
There are two terms in the right-hand side of the equation: 1200, and 400x. It is observed that the value of the first term is constant at 1200 while that of the second term is variable depending on the number of months. The first term therefore can be attributed as the deposited value.
Therefore, the answer to the question is letter D.

Answer:
Answer:
4
Step-by-step explanation:
Distance=speed times time
if they take the same time, we cal the time , t
b=bike speed
w=walking speed
bikedistnace=17=bt
walkdistance=9=wt
b is 4 more than w
b=4+w
we have
17=bt
9=wt
b=4w
ok so
multiply first equation by 9 and 2nd by 17
153=9bt
153=17wt
set equal
9bt=17wt
divide both sides by t
9b=17w
sub b=4+w for b
9(4+w)=17w
distribute
36+9w=17w
minus 9w both sides
36=8w
divide both sides by 8
4.5=w
he walks 4.5kph
