2+3x=-4(5+2x) solve for x, help please

Misha Larkins [42]

Answer:

$x=-2$

Step-by-step explanation:

$2+3x=-4.(5+2x)$

$Expand \: the \: parentheses:$

$2 + 3x = - 4.5 - 4.2x$

$Simplify \: the \: arithmetic:$

$2 + 3x = - 20 - 4.2x$

$Solve \: by \: distributing:$

$2 + 3x = - 20 - 8x$

$Group \: all \: x \: terms \: on \: the \: left \: \\ side \: of \: the \: equation$

$2 + 3x = - 20 - 8x$

$Add \: 8x \: to \: both \: sides:$

$2 + 3x + 8x = - 8x + 8x$

$Simplify \: the \: arithmetic:$

$11x + 2 = - 20 - 8x + 8x$

$Group \: like \: terms:$

$11x + 2 = - 8x + 8x - 20$

$Group \: all \: constants \: on \: the \: right \\ \: side \: of \: the \: equation$

$11x + 2 = - 8x + 8x - 20$

$Subtract \: 2 \: from \: both \: sides:$

$11x + 2 - = - 20 - 2$

$Simplify \: the \: arithmetic:$

$11x = - 20 - 2$

$Simplify \: the \: arithmetic:$

$11x = - 22$

$Isolate \: the \: x$

$11x = - 22$

$Divide \: both \: sides \: by \: 11:$

$\frac{11x}{11} = \frac{ - 22}{11}$

$Simplify \: the \: fraction:$

$x = \frac{ - 22}{11}$

$Find \: the \: greatest \: common \: factor \\ \: of \: the \: numerator \: and \: denominator:$

$x = \frac{ - 2.11}{1.11}$

$Factor \: out \: and \: cancel \: the \: greatest \\ \: common \: factor:$

$x = - 2$

Thanks!!!!!!!

Suppose a polling agency reported that 44.4% of registered voters were in favor of raising income taxes to pay down the nationa

g100num [7]

Answer:

<em>95% of confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt.</em>

<em>(0.414 ,0.474)</em>

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

<em>Given sample proportion </em>

<em> p⁻ = 44.4 % = 0.444</em>

<em>Random sample size 'n' = 1049</em>

<em>Given margin of error for 95% confidence level = 3 % = 0.03</em>

<u><em>Step(ii):-</em></u>

<em>95% of confidence interval for the proportion is determined by</em>

$(p^{-} - Z_{\alpha }\sqrt{\frac{p^{-} (1-p^{-} }{n} } , p^{-} + Z_{\alpha }\sqrt{\frac{p^{-} (1-p^{-} }{n} })$ <em></em>

we know that

<em>Margin of error for 95% confidence level is determined by</em>

$M.E = Z_{\alpha }\sqrt{\frac{p^{-} (1-p^{-}) }{n} }$

<u><em>Step(iii):-</em></u>

Now

<em> 95% of confidence interval for the proportion is determined by</em>

$(p^{-} - M.E, p^{-} + M.E)$ <em></em>

<em>Given Margin of error </em>

<em> M.E = 0.03</em>

<em>Now 95% of confidence interval for the proportion</em>

$(0.444 - 0.03, 0.444+ 0.03)$ <em></em>

<em>(0.414 ,0.474)</em>

<u><em>Conclusion:-</em></u>

<em>95% of confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt.</em>

<em>(0.414 ,0.474)</em>
