If vector u has its initial point at (-17, 4) and its terminal point at (8,-11), u= ? i + ? j. if v=14j, 2(u-v)= ? i + ? j
*the question marks stand for the blanks in the question

u=25i-15j

2(u-v)=50i-58j

Step-by-step explanation:

Vector u has its initial point at (-17, 4) and its terminal point at (8,-11).

This implies that;

u=25i-15j

If v=14j

Then

2(u-v)=2(25i-15j -14j)

2(u-v)=2(25i-29j)

2(u-v)=50i-58j

step-by-step explanation:

nobody can if you dont give the choices

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
