You walk from point a 8 miles due north, then 5 miles dues east, and then 4 miles due north to point b. how far is point a from point b on a straight line?

Point A is miles far from point B.

Step-by-step explanation:

Draw a diagram by using the given information.

1. Move 8 units up to reach at point Q. (Walk from point A ,8 miles due north).

2. Move 5 units right to reach at point R. (5 miles dues east)

3. Move 4 units down to reach at point B. (4 miles due north to point B)

4. Drawn a line PB as shown below.

From the below figure it is clear that

AP = 8-4 = 4 miles

PB = QR = 5 miles

Using Pythagoras we get

Taking square root on both sides.

Therefore, point A is miles far from point B.

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
