Formula used here ,
It is given that the distance between Meredith and her friends house =2 4 blocks
Then At Speed = 1 block per minute.
= 24 minutes.
At Speed = 2 block per minute.
= 12 minutes.
At Speed = 3 block per minute.
= 8 minutes.
At Speed = 4 block per minute.
= 6 minutes.
At Speed = 6 block per minute.
= 4 minutes.
At Speed = 8 block per minute.
= 3 minutes.
At Speed = 10 block per minute.
= 2.4 minutes.
At Speed = 12 block per minute.
= 2 minutes.
At Speed = 24 block per minute.
= 1 minute.
This problem can be solved by using the formula for
linear motions. The formula relating velocity, distance and time is:
t = d / v
where t is time, d is distance and v is velocity
We are given that d = 24 blocks
When v = 1 block / minute
t = 24 blocks / (1 block / minute)
t = 24 minutes
When v = 2 block / minute
t = 24 blocks / (2 block / minute)
t = 12 minutes
Hence we can see that it takes half the time when she is
travelling at 2 blocks per minute.
Step-by-step explanation:
So in the equation given, y = 2x -3
you substitute x for whats given in the table in the x column.
Example
In the graph the first number under the x colum is -1.
y = 2x - 3 in the equation you take out x and put -1.
So now the equation becomes y = 2 × -1 - 3.
Using bedmas to solve the question you should get -5
Which now means y = -5
To plot the point now x would be -1 and y would be -5 (-1, -5)
Same thing for the second number in the x Column.
y = 2 × 1 - 3 which equals -1
To plot it
x = 1 y = -1. (1, -1)
And for the last number 3.
Agai. You substitute x for 3 which makes the equation y = 2 × 3 - 3
this gives you 3 and to plot it
x would be 3 and y would be 3
