Answer:
uh what about bang thats four words id.k
Step-by-step explanation:
Use elimination and subtitution method to solve the problem.
First, eliminate x and you'll find the value of y
x - 4y = 12
x - y = 0
--------------- - (substract)
-3y = 12
y = 12/-3
y = -4
Second, subtitute -4 as y and you'll find the value of x
x - y = 0
x- (-4) = 0
x + 4 = 0
x = -4
The solution
x,y = -4,-4
y = 7 + 3x
y = 3x + 7
y = mx + b, therefore the y-intercept is 7.
3y = 6x + 12
y = 2x + 4
y = mx + b, therefore the y-intercept is 4.

Answer:
He should travel directly
Step-by-step explanation:
Given
--- East
--- North
If he goes through east north direction, the distance (d) traveled is:



If he travels directly, the distance (d) is:
---- Pythagoras theorem




By comparison, he will travel the shortest distance if he travels directly because 
<em>Hence, he should travel directly</em>
