Answer:

x = 3

Step-by-step explanation:

This answer will be about a day late, but I hope you can take something from it.

The scale factor is 6:8, or 3:4.

3/4 × 4 = 3

OR: Set Up A Proportion:

\frac{6}{x}  \times  \frac{8}{4}

<em>cross-mutliply</em>

8x = 24

x = 3

Solve each given equation and show your work. Tell whether it has one solution, an infinite number of solutions, or no solutions
WITCHER [35]
Solve   <span>6x+4x-6=24+9x.  Combine all the x terms on one side and all the constants on the other:

10x-9x = 24+6, or x = 30.  ONE soution.


Solve   </span><span>4x+8=2x+7 +2x-20.  Combine all the x terms on one side and all the constants on the other:  4x - 2x - 2x = 7 - 20 - 8 =>   0 = -21

This is NEVER true, so   </span><span>4x+8=2x+7 +2x-20    has NO SOLUTION.

Please try solving equation B yourself.  Then I'd gladly comment on your work.</span>

MATRECIES: Suppose ={u,v,w}⊆R3 is linearly independent. Determine if the set 4 ={u, v, v−w, u+v+w} is linearly independent or li
AlladinOne [14]

The set is linearly dependent.

To explicitly prove this, we need to show there is at least one choice of constants c_1,c_2,c_3,c_3\in\Bbb R such that

c_1 u + c_2 v + c_3(v-w) + c_4(u+v+w) = 0

or equivalently,

(c_1 + c_4) u + (c_2 + c_3 + c_4) v + (-c_3 + c_4) w = 0

which is the same as solving the system of equations

\begin{cases} c_1 + c_4 = 0 \\ c_2 + c_3 + c_4 = 0 \\ -c_3 + c_4 = 0 \end{cases}

From the first and last equations, we have c_1=-c_4 and c_3=c_4. Substituting these into the second equation leaves us with c_2-2c_1=0, and so the overall solution set is

c_1 = \dfrac12 c_2 = -c_3 = -c_4

for which there are infinitely many not-all-zero solutions.
