Answer:

\boxed{u = \pm \sqrt{ {v}^{2} - 2as}}

\boxed{s =  \frac{ {v}^{2}  -  {u}^{2} }{2a}}

Step-by-step explanation:

<em>•</em><em>Making u subject for </em><em>f</em><em>ormula v² = u² + 2as:</em>

Solve \:  for \:  u:  \\ =  >  {v}^{2}  = {u}^{2} +2as \\  \\ {v}^{2}  = {u}^{2}  + 2as \:  is \:  equivalent \:  to \:    {u}^{2}  + 2as = {v}^{2} : \\  =  >  {u}^{2}  + 2as =  {v}^{2}  \\  \\ Subtract  \: 2as  \: from \:  both \:  sides:  \\  {u}^{2}   =  {v}^{2}  - 2as \\  \\ Take \:  the  \: square \:  root \:  of  \: both \:  sides:  \\  =  > u= \sqrt{ {v}^{2} - 2as }   \:  \: \:  \:  or \:  \:  \:  \:  u=- \sqrt{ {v}^{2} - 2as} \\ u = \pm \sqrt{ {v}^{2} - 2as}

<em>•</em><em>Making</em><em> s subject for formula v² = u² + 2as:</em>

<em>Solve  \: for  \: s:  \\  =  > {v}^{2}  =2as+ {u}^{2}  \\  \\ {v}^{2}  =2as+ {u}^{2} is equivalent to 2as+ {u}^{2} = {v}^{2}:  =  >  2as+ {u}^{2} = {v}^{2} \\   \\ Subtract  \:  {u}^{2}   \: from  \: both \:  sides:  \\  =  > 2as= {v}^{2}  -  {u}^{2} \\  \\ Divide  \: both \:  sides \:  by  \: 2 a:  \\  =  > s =  \frac{ {v}^{2} }{2a}  -  \frac{ {u}^{2} }{2a}  \\  =  > s =  \frac{ {v}^{2}  -  {u}^{2} }{2a}</em>

Answer:

s = \frac{v^2-u^2}{2a}

Step-by-step explanation:

Given

v² = u² + 2as ( subtract u² from both sides )

v² - u² = 2as ( divide both sides by 2a )

\frac{v^2-u^2}{2a} = s

Given

v² = u² + 2as ( subtract 2as from both sides )

v² - 2as = u² ( take the square root of both sides )

± \sqrt{v^2-2as} = u

4x−2y=14 y=12x−1 solve by substitution
Tatiana [17]

Answer:

x= -3/5

Step-by-step explanation:

4x-2y=14

y=12x-1

4x-2(12x-1)=14

4x-24x+2=14

4x-24x=12

-20x=12

×= -12/20

x= -3/5

Slav-nsk [51]

Answer:

\large\boxed{-5\leq k

Step-by-step explanation:

5+7k\geq-30\ \wedge\ -4k+4>20\\\\5+7k\geq-30\qquad\text{subtract 5 from both sides}\\7k\geq-35\qquad\text{divide both sides by 7}\\\boxed{k\geq-5}\\\\-4k+4>20\qquad\text{subtract 4 from both sides}\\-4k>16\qquad\text{change the signs}\\4k
