<h3>Solution:</h3>

firstly solve parenthesis bracket ( )

-4×3 + 4×5x ≥ -6x + 9

-12 + 20x ≥ -6x + 9

Add 12 on both sides

-12 + 12 + 20x ≥ -6x + 9 + 12

20x ≥ -6x + 21

Add 6x on both sides

6x+ 20x ≥ -6x + 6x + 21

26x ≥  21

divide both side by 26

26 x/26 ≥21/26

x ≥21/26

A very small sphere with positive charge 5.00uC is released from rest at a point 1.20cm from a very long line of uniform linear
JulijaS [17]
Let us situate this on the x axis, and let our uniform line of charge be positioned on the interval <span>(−L,0]</span> for some large number L. The voltage V as a function of x on the interval <span>(0,∞)</span> is given by integrating the contributions from each bit of charge. Let the charge density be λ. Thus, for an infinitesimal length element <span>d<span>x′</span></span>, we have <span>λ=<span><span>dq</span><span>d<span>x′</span></span></span></span>.<span>V(x)=<span>1/<span>4π<span>ϵ0</span></span></span><span>∫line</span><span><span>dq/</span>r</span>=<span>λ/<span>4π<span>ϵ0</span></span></span><span>∫<span>−L</span>0</span><span><span>d<span>x/</span></span><span>x−<span>x′</span></span></span>=<span>λ/<span>4π<span>ϵ0</span></span></span><span>(ln|x+L|−ln|x|)</span></span>
