The "dot product" of two vectors has several different formulas.
Since you are given the x- and y-coordinates of both vectors a and b, we can apply the formula
a dot b = ax*bx + ay*by, where ax=x-component of vector a, by=y comp of vector b, and so on.
So, for the problem at hand, ax * bx + ay * by becomes
3(-2) + (-8)(-6) = -6 + 48 = 42 (answer). Note that the dot product (or "scalar product" is itself a scalar.
Yes you are correct with that answer

Answer:
444,444
Step-by-step explanation:
total amount=737373
jerry=292929
Brandon=unknown
To figure the amount of video games Brandon has, we have to subtract the amount of both he and his friend altogether amount with Jerry's current amount of video games.
737,373-292,929=444,444
So, by subtracting the two, the answer would be 444,444.
Brandons total amount of video games:444,444
