Answer with Step-by-step explanation:
We are given that
u+ v and u-v are orthogonal
We have to prove that u and v must have the same length.
When two vector a and b are orthogonal then
By using the property
We know that
Magnitude is always positive
When power of base on both sides are equal then base will be equal
Therefore,
Hence, the length of vectors u and v must have the same length.
Answer:
you can change x=0=>y=-7/2 or
y=0=> x=2
I think it’s AC, but I may be wrong
Answer:
Step-by-step explanation:
Let's solve:
Step 1: Simplify both sides of the equation.
Step 2: Add 3x to both sides.
Step 3: Subtract 4 from both sides.
Step 4: Divide both sides by -1.
Therefore, the answer will be x = 4.
