Which equation has no solution? a. 7w+8-w=9w-2(w-4) b. 3m-2=5m+3-m c. 8-(3v+7)=3v-1 d. -4y+5=-4y-8

To check , whether the given equation has solution or not, lets start with first one

A.

Open the parenthesis, and simplify

B.

C.

Take like terms together and simplify we get

D.

Take like terms together

Hence this equation has no solution.

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°
