Answer:

<h2><em><u>k</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>3</u></em></h2>

Step-by-step explanation:

<h3><em><u>Given</u></em><em><u>,</u></em></h3>
  • To find the value of k

<h3><em><u>Equation</u></em><em><u>:</u></em></h3>
  • -2k - 4k = -18

<h3><em><u>Solution</u></em><em><u>:</u></em></h3>

=> -2k - 4k = -18

  • <em>(</em><em>On</em><em> </em><em>adding</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em><em>-</em><em>2k</em><em> </em><em>and</em><em> </em><em>-4k</em><em>)</em>

=> -6k = -18

  • <em>(</em><em>As</em><em> </em><em>-6</em><em> </em><em>multiplied</em><em> </em><em>with</em><em> </em><em>k</em><em> </em><em>in</em><em> </em><em>this</em><em> </em><em>side</em><em>,</em><em> </em><em>on</em><em> </em><em>other</em><em> </em><em>side</em><em> </em><em>it</em><em> </em><em>will</em><em> </em><em>divide</em><em> </em><em>-18</em><em>)</em>

=  > k =  \frac{ - 18}{ - 6}

  • <em>(</em><em>On</em><em> </em><em>Simplification</em><em>)</em>

=> <em><u>k</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>3</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

3x-y= 17<br> -x+y= -7<br><br> Help please
AlexFokin [52]

Answer:

y = -2

x = 5

Step-by-step explanation:

3x - y = 17

-x + y = -7

here we can find the sum of the two equations

2x = 10

x = 5

now we can just plug in the value of x to find y

-(5) + y = -7

y = -2

Someone please help. thanks!

Answer:  (-0.61, 5.85) and (-2.72, 3.04)

<u>Step-by-step explanation:</u>

y = 2x² + 8x + 10

y = -x² - 2x + 5

Use substitution method to get:   2x² + 8x + 10 =  -x² - 2x + 5

Move everything to one side and 0 on the other: 3x² + 10x + 5 = 0

Use the quadratic formula to solve for x: \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}

x=\dfrac{-(10)\pm \sqrt{(10)^2-4(3)(5)}}{2(3)}\\\\\\.\ =\dfrac{-10\pm \sqrt{100-60}}{6}\\\\\\.\ =\dfrac{-10\pm \sqrt{40}}{6}\\\\\\.\ =\dfrac{-10\pm 2\sqrt{10}}{6}\\\\\\.\ =\dfrac{-5\pm \sqrt{10}}{3}

x₁ = -0.61                                    x₂ = -2.72

Next, input the x-values to solve for y:

y₁ = -x² - 2x + 5                          y₂ = -x² - 2x + 5

   = -(-0.61)² - 2(-0.61) + 5              = -(-2.72)² - 2(-2.72) + 5

   =  -0.37 + 1.22 + 5                     = -7.40 + 5.44 + 5

   =  5.85                                       = 3.04
