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

Which statement illustrates the Distributive Property of scalar multiplication? (Assume that A and B are matrices and c and d ar

olasank [31]

Answer:

C. $cA-cB=c(A-B)$

Step-by-step explanation:

Given that A and B are matrices and $c$ is a scalar, then the distributive property of scalar multiplication over addition is given by;

$c(A+B)=cA+cB$

The distributive property of scalar multiplication over subtraction is

$c(A-B)=cA-cB$

The correct answer is C.

How do you find the range of a function?

NISA [10]

<span>For more difficult cases, it may be easier to draw the graph first using the domain if possible and then determine the range graphically.See if you can find the inverse function. The domain of a function's inverse function is equal to that function's range.<span>Check to see if the function repeats.</span></span>
