Finallyyy the last one

B and C

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (8, - 7) and (x₂, y₂ ) = (4, - 3)

d = → B

  = 4 → C

Step-by-step explanation:

The formula for finding the distance between two lines is:

where d is the distance between the points (x₁, y₁) and (x₂, y₂).

By using the distance formula, we can find that the distance between (8, -7) and (4, -3) is:

So we know that

is one answers to the question. To find the other answer, if there is one, we will have to evaluate the distance between the two points.

So now we know that

is another one of the answers. Since none of the other answer are equal to each other, those are the only two answers.

I hope you find this helpful.

irrational, cannot

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
