First, we need to find the slope:
m=rise/run OR

m=(2+2)/(-6-2)
m=4/-8
m=-1/2

second we need to find the equation for the line using point-slope form:

y-(-2)=-(1/2)(x-2)

to find "a" we plug in the given y value and solve for x (in this case x=a):

so, a=6 and the point becomes (6,-4)

Aleksandr-060686 [28]

Answer:

Option B

Step-by-step explanation:

step 1

Find the number of cubes in the prism

$(3)(2)(3)=18\ cubes$

step 2

Find the volume of one cube

The volume of one cube is equal to

$V=b^3$

where

b is the length side of the cube

we have

$b=\frac{1}{3}\ in$

substitute

$V=(\frac{1}{3})^3$

$V=\frac{1}{27}\ in^3$

step 3

To find out the volume of the prism , multiply the volume of one cube by the number of cubes

so

$V=(\frac{1}{27})18$

$V=\frac{18}{27}\ in^3$

simplify

$V=\frac{2}{3}\ in^3$

Let S = {A, B, C, D} be some set of four elements of a vector space. Suppose that D = 2A + B + 3C and C = A − B. Is {A, B, D} li

Olin [163]

Answer:

As explained

Step-by-step explanation:

given that D = 2A + B + 3C and S = {A, B, C, D}, C = A − B

for {A, B, D} to be linearly dependent implies that A B and D will have values that not dependent on the sample space C.

if C = A -B is substituted in the original equation, the generated equation, 5A -2B will have values each as against C which is linearly independent.

Also, D will have values that are linearly dependent.
