Answer:
19
Step-by-step explanation:
u =<2,5> v=<7,1>
The dot product is the scalar sum of products of corresponding components:
u·v = 2·7 + 5·1 = 14 +5 = 19
The dot product is 19.
With only one equation and no answer choices, there are an infinite number of possible values for x and y to make the equation true.
The answer is 7 because honestly I just don’t know what to put
