Find the slope and the y-intercept of the equation 4x + 5y=-9. O A. slope = 4/5' and y-intercept = `-(9)/(5)
slope = '-(4)/(5) and y-intercept = (9)/(5)
OC. slope = \-(4)/(5) and y-intercept = -(9)/(5)
OD. slope = (4)(5) and y-intercept = `975

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°

hope this

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

answer: i think it is (1,-2)
