u • v = x₁x₂ + y₁y₂

Given

u = < \sqrt{3}, - 1 > and v = < 3, - 4 >, then

u • v = 3\sqrt{3} + (- 1)(- 4) = 3\sqrt{3} + 4

Answer:

y = -40

Step-by-step explanation:

|y/5+8| - 3 = -3

|y/5+8| = -3 + 3 = 0

y/5+8 = 0 or -0 but 0 and -0 are the same so there would be only 1 answer for this:

Subtract both side by 8

y/5 = -8

Times 5, we got:

y = -40
