a system of equations is shown.

2m - n = -14
-1m + 3n = 17

what is the value of n?

a. 14
b. 4
c. -5
d. 10

b.

Step-by-step explanation:

{2m - n = −14

{−m + 3n = 17

⅓[−m + 3n = 17]

{2m - n = −14

{−⅓m + n = 5⅔

____________

1⅔m = −8⅓

____ ____

1⅔ 1⅔

[Plug this back into both equations above to get the n-value of 4];

Therefore, our n-value is 4.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

it is only things thain can be deafeated
