7x-8y=9 -4x+9y=-22

Please help I can’t seem to have the answer

i got you ;)

Step-by-step explanation:

Point Form:  (  − 95 /31 ,  −  118 /31 )

Equation Form:  x  =  − 95 /31 ,  y  =  − 118 /31

hope that helps

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
