Hi, i need to calculate roots x1 and x2 using the vieta theorem, can anyone help me? I have found the answer for x1 and x2, its

Mnenie [13.5K]

Answer:

Solution given:

-2x²+7x-6=0

2x²-7x+6=0

Comparing above equation with ax²+bx+c

we get

a=2

b=-7

c=6

By using Vieta's theorem

X1+X2= $\frac{-b}{a}$ = $\frac{7}{2}$

again

X1X2= $\frac{c}{a}$ = $\frac{6}{2}$ =3

Write the equation of the line in slope-intercept form that is parallel given the equation and point.

KiRa [710]

Answer:

$y = \frac{4x}{5}+\frac{42}{5}$

Step-by-step explanation:

In order for two lines to be parallel, they must have the same slope. So, we know that the slope of the other line is 4/5.

We're given an ordered pair, so we can solve for $b$ in the (slope-intercept form) equation $y = mx + b$

$2 = \frac{4}{5}(-8) + b\\2 = \frac{-32}{5}+b\\b = 2 + \frac{32}{5}\\ b = \frac{42}{5}$

$y = \frac{4x}{5}+\frac{42}{5}$

<h3>Answer: 5</h3>

Work Shown:

$m = \frac{6^{n+2}-6^{n}}{6^{n+1}+6^{n}}\\\\m = \frac{6^{n}*6^2-6^{n}}{6^{n}*6^1+6^{n}}\\\\m = \frac{6^{n}*36-6^{n}}{6^{n}*6+6^{n}}\\\\m = \frac{6^{n}(36-1)}{6^{n}(6+1)}\\\\m = \frac{6^{n}(35)}{6^{n}(7)}\\\\m = \frac{35}{7}\\\\m = 5\\\\$

Therefore,

$\frac{6^{n+2}-6^{n}}{6^{n+1}+6^{n}}=5\\\\$
