X+y=10
5x+y=-2
What is the y and x value

x = - 3, y = 13

Step-by-step explanation:

Given the 2 equations

x + y = 10 → (1)

5x + y = - 2 → (2)

Subtracting (1) from (2) term by term eliminates the y- term, that is

(5x - x) + (y - y) = (- 2 - 10), that is

4x = - 12 ( divide both sides by 4 )

x = - 3

Substitute x = - 3 in either of the 2 equations for corresponding value of y

Substituting x = - 3 into (1), gives

- 3 + y = 10 ( add 3 to both sides )

y = 13

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°
