Answer:

u\cdot v=32

Step-by-step explanation:

Assuming u and v are vectors, their dot product is u\cdot v where u_1v_1 + u_2v_2:

u\cdot v=u_1v_1+u_2v_2=(2)(8)+(-8)(-2)=16+16=32

Therefore, u\cdot v=32

What’s the answer to this ?
dybincka [34]

Answer:

First choice

Step-by-step explanation:

It passes through (4, 0) and (0, -4)

Slope = (0 - (-4))/(4 - 0) = 4/4 = 1

so y - 0 = 1*(x - 4)

x - y = 4

8x - 8y = 32
