Answer:

Now, 3x 2+x+5⩾0

This is because b² −4ac=1−4×5×3

=−59 (roots are imaginary)

3x²+x+5=(x−3)² =x²+9−6x and x−3⩾0

2x²+7x−4=0

2x²+8x−x−4=0

2x(x+4)−1(x+4)=0

(2x−1)(x+4)=0

x= 1/2 and−4 but x≥3

∴ No solution.

lol hehehe

Answer:

\huge \bf༆ Answer ༄

Step-by-step explanation:

Let's solve for x ~

  • \sf \dfrac{1}{3}  {x}^{2}  + x +  \dfrac{5}{3} {x}^{2}   =  \dfrac{1}{9}

  • \sf \dfrac{(1 + 5)}{3}  {x}^{2}  + x =  \dfrac{1}{9}

  • \sf \dfrac{6}{3}  {x}^{2}  + x -  \dfrac{1}{9}  = 0

  • \sf2 {x}^{2}  + x -  \dfrac{1}{9}  = 0

Multiply each term with 9 on both sides of the equation

  • \sf(2 {x}^{2}  \times 9) + (x \times9 ) - ( \dfrac{1}{9}  \times 9 ) = 0 \times 9

  • \sf18 {x}^{2}  + 9x - 1 = 0

Now, let's use Quadratic formula to find its roots ~

\sf  \dfrac{  -  {b}^{}  \pm \sqrt{b {}^{2}  - 4ac} }{2a}

where,

  • b is Coefficient of x = 9

  • a is Coefficient of x² = 18

  • c is the constant term = -1

Let's find the roots ~

  • \sf  \dfrac{ - 9 \pm \sqrt{(9 {}^{2}) - (4 \times 18 \times  - 1) } }{2 \times 18}

  • \sf  \dfrac{ - 9 \pm \sqrt{81- ( - 72) } }{36}

  • \sf  \dfrac{ - 9 \pm \sqrt{81 +  72} }{36}

  • \sf  \dfrac{ - 9 \pm \sqrt{153} }{36}

  • \sf  \dfrac{ - 9 \pm 3\sqrt{17} }{36}

  • \sf \dfrac{3( - 3 \pm \sqrt{17} )}{36}

  • \sf \dfrac{ - 3 \pm \sqrt{17} }{12}

Therefore the value if x are ~

  • \sf \dfrac{ - 3  +  \sqrt{17} }{12}  \:  \: and \:  \: \sf \dfrac{ - 3  -  \sqrt{17} }{12}

I hope it helps ~

At a football stadium, 25% of the fans in attendance were teenagers. If there were 130 teenagers at the football stadium, what w
Trava [24]

Answer:

Total number of people in the stadium = 520

Step-by-step explanation:

Let the total number of people in the stadium = x

Since, 25% of the fans are teenagers, number of teenagers in the stadium

= 25% of x

= \frac{25}{100}\times x

= 0,25x

If the number of teenagers in the stadium = 130

0.25x = 130

x = \frac{130}{0.25}

x = 520

Therefore, total number of fans in the stadium = 520.
