Answer:
.
Step-by-step explanation:
Two vectors 
and 
are parallel to one another if and only if the ratio between their corresponding components are equal:
.
Equivalently:
.
For the two vectors in this equation to be parallel to one another:
.
Solve for 
:
.
would be the only valid value of ; no other value would satisfy the equation.
Error is between steps 4 and 5. It should say:
Step 4: -9x < 27
Now divide by -9
Step 5: x > -3
Note that the inequality changes direction.
When you mean multiply or divide an inequality by a negative number, the inequality changes direction.
For example:
4 < 5
Multiply by -1:
-4 > -5
Another example:
-5 < 0
5 > 0
Answer:
5.) b = -2/5 (or -0.4 in decimal form)
6.) 20.5
