Answer:
k = 5
Step-by-step explanation:
k/2+1/2=3
Multiply each side by 2 to get rid of fractions
2(k/2+1/2)=3*2
k+1 = 6
Subtract 1 from each side to isolate k
k+1-1 = 6-1
k = 5
Answer:
Third option <3, 9>
Step-by-step explanation:
u and v are two vectors and we know the Cartesian components of these vectors.
We must find the sum of u + v.
If we have the Cartesian components of both vectors then the sum of both is done by adding the components of u with the components of v.


Where i is the vertical component and j is the horizontal component
Then u + v is
