Write an equation in standard form for the line that has slope 1/3 and passes<br> through (-2, 8)
Y_Kistochka [10]

Answer:

<h2>         -x + 3y = 26            </h2>

Step-by-step explanation:

The equation of a line which passes through <em>(x₁, y₁)</em> and with slope of <em>m</em> in point-slope form:

                              y - y₁ = m(x - x₁)

m = ¹/₃

(-2, 8)    ⇒   x₁ = -2,  y₁ = 8

Therefore,  the equation of the line which passes through (-2, 8) and with slope of 1/3 in point-slope form:

y - 8 = ¹/₃(x - (-2))

y - 8 = ¹/₃x + ²/₃                   {multiply both sides by 3}

3y - 24 = x + 2                    {subtract x from both sides}

-x + 3y - 24 = 2                     {add 24 to both sides}

-x + 3y = 26

Find the solutions to the equation below 30x^2-28x+6 =0
Naddik [55]

For this case, we have the following equation of the second degree:

30x ^ 2-28x + 6 = 0

If we divide between 2 on both sides of the equation, we will have:

15x ^ 2-14x + 3 = 0

Where:

a = 15\\b = -14\\c = 3

The solutions will come from:

x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}

Substituting:

x = \frac {- (- 14) \pm \sqrt {(- 14) ^ 2-4 (15) (3)}} {2 (15)}\\x = \frac {14 \pm \sqrt {196-180}} {30}\\x = \frac {14 \pm \sqrt {16}} {30}\\x = \frac {14 \pm4} {30}

So, we have:

x_ {1} = \frac{14 + 4} {30} = \frac {18} {30} = \frac {18} {30} = \frac {3} {5}\\x_ {2} = \frac {14-4} {30} = \frac {10} {30} = \frac {1} {3}\\

Answer:

x_ {1} = \frac {3} {5}\\x_ {2} = \frac {1} {3}

Option E
