amid [387]

Answer:

x =   \bigg \{\frac{ 2   - \sqrt{2} \: i }{3}, \:  \: \frac{ 2    +  \sqrt{2} \: i }{3} \bigg \}

Step-by-step explanation:

3 {x}^{2}  - 4x =  - 2 \\ 3 {x}^{2}  - 4x + 2 = 0 \\ equating \: it \: with  \\ a {x}^{2}  + bx + c = 0 \\ a = 3 \:  \: b =  - 4 \:  \: c = 2 \\  {b}^{2}  - 4ac \\  =  {( - 4)}^{2}  - 4 \times 3 \times 2 \\  = 16 - 24 \\  =  - 8  \\  \ {b}^{2}  - 4ac < 0  \\  \therefore \: given \: quadratic \: equation \: have \:  \\ imaginary \: solutios. \\  \\ x =  \frac{ - b \pm \sqrt{{b}^{2}  - 4ac } }{2a}  \\ =  \frac{ - ( - 4) \pm \sqrt{ - 8} }{2 \times 3} \\ =  \frac{ 4 \pm 2\sqrt{2} \: i }{2 \times 3}  \\  =  \frac{ 2 \pm \sqrt{2} \: i }{3} \\  \therefore \: x  = \frac{ 2   - \sqrt{2} \: i }{3}  \: or \: x  = \frac{ 2   +  \sqrt{2} \: i }{3} \:  \\  \\ x =   \bigg \{\frac{ 2   - \sqrt{2} \: i }{3}, \:  \: \frac{ 2    +  \sqrt{2} \: i }{3} \bigg \}

5x + 3 = x + 11<br> Please help
taurus [48]

Answer:

2

Step-by-step explanation:

5x + 3 = x + 11

5x - x + 3 = x - x + 11

4x + 3 = 11

4x + 3 - 3 = 11 - 3

4x = 8

4x / 4 = 8/ 4

x = 2

Hope this helps ^-^

Debora [2.8K]

Answer:

The fraction of the students that walk in in Marla's school  is equal to \frac{2}{9}

Step-by-step explanation:

Let

x------> the total students in Marla's school

we know that

The number of students that not ride the bus is equal to

\frac{6}{15}x\ students

The number of students that walk to the school is equal to

\frac{6}{15}x*\frac{5}{9}=\frac{2}{9}x\ students

therefore

The fraction of the students that walk in in Marla's school  is equal to \frac{2}{9}
