What values of k will make the line containing points (k,3) and (-2,1) parallel to the line through (5, K) and (1,0)

rjkz [21]

Answer:

k = -4 or 2

Step-by-step explanation:

For the lines to be parallel, the lines would need to be the same slope. This means to find the slope of each we would take the difference of the rise over the run.

$\frac{1-3}{-2-k}=\frac{-2}{-2-k}$

and

$\frac{0-k}{1-5}=\frac{-k}{-4}$

To find K, set them equal.

$\frac{-2}{-2-k} = \frac{-k}{-4}\\-k(-2-k) = -2*-4\\2k+k^2=8\\k^2+2k-8=0$

Factor the quadratic and solve for K.

$(k+4)(k-2)=0$

k+4=0 so k=-4

k-2=0 so k=2

Write this statement as a conditional in if-then form:. . All triangles have three sides.. . (1 point). If a triangle has three

ehidna [41]

The correct answer is:

If a figure is a triangle, then it has three sides.

Explanation:

A conditional is an if-then statement. The part after "if" is called the hypothesis; the part after "then" is called the conclusion.

We know that triangles have 3 sides. We will start out with "if a figure is a triangle"; we end with "then it has three sides."

This is a true conditional statement.
