Answer:
B. d = 5/3t
Step-by-step explanation:
The complete question is shown in the figure attached with.
We need to find the equation of direct variation using the graph. The general equation for a direction variation is:
y = kx
In this case, the variable along x axis is time in seconds i.e. "t" and the variable along y axis is distance in meters i.e. "d". So, the equation for this case would be:
d = kt
We need to find the value of "k" to complete this equation. For this we can use any point from the graph and substitute it in the above equation. From the graph we can see that the distance covered for time = 3 seconds is 5 meters. Substituting t =3 and d = 5 in above equation, we get:
5 = 3k
k = 5/3
Using the value of k in the above equation, we get:

Therefore, option B gives the correct answer
Answer:
6:10.
Step-by-step explanation:
4 : 40 + 1 : 30 = 5 : 70
because 60 minutes make an hour and on the minutes side has more than 60, we have to minus 60 minutes and carry the one hour to the other side which is the Hour side.
5 : 70........ minus 60 to get 10.
5 + 1 to get 6.
therfore it is 6 : 10
Both a and b are functions. for it to be a function, you can only have 1 y value per x value.
this is not a function because 1 has 2 y values
(1,3)(2,5)(1,4)(3,2)
