(1 point) Let {u1,u2,u3} be an orthonormal basis for an inner product space V. If v=au1+bu2+cu3
is so that ∥v∥=12, v is orthogonal to u3, and ⟨v, u2⟩=−12, find the possible values for a, b, and c.

a=
, b=
, c=
​

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

5+2x=a

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
