Solve for w: -5(3-w)+4=-5/6(24-6w)
AfilCa [17]

Answer:

no solution

Step-by-step explanation:

well first you gotta distribute

-5(-3 - w) + 4 = -5/6(24 - 6w)

15 + 5w + 4 = -20 + 5w

19 + 5w = -20 + 5w

+20           +20

39 + 5w = 5w

      -5w    -5w

39 ≠ 0

therefore there is no solution (which is the answer)

Use elimination to solve the system of equations:
tatyana61 [14]
<span><span><span><span>2x</span>+<span>3y</span></span>=1</span>;<span><span>x+<span>4y</span></span>=<span>−2

</span></span></span>Steps:

<span>Multiply the second equation by -2, then add the equations together.

</span><span>(<span><span><span>2x</span>+<span>3y</span></span>=1</span>)

</span><span><span>−2</span><span>(<span><span>x+<span>4y</span></span>=<span>−2</span></span>)

</span></span>Becomes:

<span><span><span>2x</span>+<span>3y</span></span>=1

</span><span><span><span>−<span>2x</span></span>−<span>8y</span></span>=4

</span>Add these equations to eliminate x:

<span><span>−<span>5y</span></span>=5

</span>Then solve<span><span>−<span>5y</span></span>=5</span>for y:

<span><span><span>−<span>5y</span></span><span>−5</span></span>=<span>5<span>−5</span></span></span>(Divide both sides by -5)

<span>y=<span>−1

</span></span>Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

<span><span><span>2x</span>+<span>3y</span></span>=1

</span>Substitute<span>−1</span>foryin<span><span><span><span>2x</span>+<span>3y</span></span>=1</span>:

</span><span><span><span>2x</span>+<span><span>(3)</span><span>(<span>−1</span>)</span></span></span>=1

</span><span><span><span>2x</span>−3</span>=1</span>(Simplify both sides of the equation)

<span><span><span><span>2x</span>−3</span>+3</span>=<span>1+3</span></span>(Add 3 to both sides)

<span><span>2x</span>=4

</span><span><span><span>2x</span>2</span>=<span>42</span></span>(Divide both sides by 2)

<span>x=2

</span>Answer:

<span><span>x=<span><span>2<span> and </span></span>y</span></span>=<span>−<span>1

Given the following sequence, find the 12th term: {2, -4, 8,...} -4096 4096 2048 -2048
Nata [24]

Answer:

- 4096

Step-by-step explanation:

There is a common ratio between consecutive terms of the sequence.

r = - 4 ÷ 2 = 8 ÷ - 4 = - 2

This indicates the sequence is geometric with n th term

a_{n} = a r^{n-1}

where a is the first term and r the common ratio

Here a = 2 and r = - 2 , thus

a_{12} = 2 × (-2)^{11} = 2 × - 2048 = - 4096
