Equation for ( 6, 13) ( 7900, 5 )

tia_tia [17]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

$y=mx+b$

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following points through which the line passes:

$(x_ {1}, y_ {1}) :( 6,13)\\(x_ {2}, y_ {2}): (7900,5)$

We find the slope of the line:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {5-13} {7900-6} = \frac {-8} {7894} = - \frac {4} {3947}$

Thus, the equation of the line is of the form:

$y = - \frac {4} {3947} x + b$

We substitute one of the points and find b:

$13 = - \frac {4} {3947} (6) + b\\13 = - \frac {24} {3947} + b\\13+ \frac {24} {3947} = b\\b = \frac {51335} {3947}$

Finally, the equation is:

$y = - \frac {4} {3947} x + \frac {51335} {3947}$

Answer:

$y = - \frac {4} {3947} x + \frac {51335} {3947}$

Write the left side of each equation as a product of linear factors, and state the solutions.

Amiraneli [1.4K]

Answer:

a). $x_{1}=1$ , $x_{2}=1$ , $x_{3}=1$

b). $x_{1}=2$ , $x_{2}=2$ , $x_{3}=2$

c). $x_{1} = \sqrt{-5}$ , $x_{2} = \sqrt{-5}$ , $x_{2} = \sqrt{-2}$ , $x_{4} = \sqrt{-2}$

Step-by-step explanation:

a.

$x^{3}-1=0\\x^{3}=1\\ x=(1 )^{\frac{1}{3} }$

$x=1$

b.

$x^{3}+8=0\\x^{3}=-8\\ x=(-8 )^{\frac{1}{3} }$

$x= 2i$

c.

$x^{4} +7x^{2} +10=0\\x^{4}=u^{2} \\x^{2}=u\\ u^{2}+7u+10=0\\$

Using

$\frac{-b+/-\sqrt{7^{2}-4*a*c } }{2*a}$

$u=\frac{-7+/-\sqrt{7^{2}-4*10}}{2}=-\frac{7}{2} +/- \frac{\sqrt{49-40} }{2} \\ u=-\frac{7}{2} +/- \frac{3}{2} \\u_{1}= -5\\u_{2}= -2$

But u is no the factor is x so:

$x=\sqrt{u}\\ x_{1} =\sqrt{-5} =5i\\ x_{2} =\sqrt{-2} =2i$

Check:

$(\sqrt{5i})^{4} +7*(\sqrt{5i})^{2} +10=0\\25*i^{4} +7*5*i^{2}+10=0\\ 25*1+7*5*-1+10\\25-35+10=0\\0=0$
