Which of the vectors a = (1,2), b = (0,1), c = (−2,−4), u = (−2,1) , v = (2,4), w = (−6,3) are: Orthogonal?

In the same direction?

In opposite directions?

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
