Answer:
y = -2x -2
x + 2y = 2
2x + y = -2 } x1
x + 2y = 2 } x2
2x + y = -2 } we eliminate 2x
2x + 4y = 4 } same signs subtract and different add respectively
-3y = -6
-3 -3
y = 2 (x , 2) we reserve
2x + (2) = -2 we take on the first equation and replace 2 on a coordinate for y
2x = -2 - 2
2x = -4
2 2
x = -2 (-2,2)
x y
Answer:
2 miles = 3218.6m
3km = 3000m
ATQ, 2 miles - 3km = 3218.6m - 3000m =
<em><u>218.6m</u></em>
Answer:
The answer is B. 132
Step-by-step explanation:
Answer: y= -1/5x + 3
15y= -3x + 45
y= -3/15x + 3
y= -1/5x + 3
