Suppose the roots of the equation 2x^2−5x−6=0 are α and β.Find the quadratic equation with roots 1/α and 1/β.

Answer:

6x² + 5x - 2 = 0

Step-by-step explanation:

Given

2x² - 5x - 6 = 0 ← in standard form

with a = 2, b = - 5, c = - 6, then

sum of roots α + β = - $\frac{b}{a}$ = $\frac{5}{2}$

product of roots = $\frac{c}{a}$ = - 3, then

sum of new roots = $\frac{1}{\alpha }$ + $\frac{1}{\beta }$

= $\frac{\beta+\alpha }{\alpha \beta }$

= $\frac{\frac{5}{2} }{-3}$ = - $\frac{5}{6}$

product of new roots = $\frac{1}{\alpha }$ × $\frac{1}{\beta }$

= $\frac{1}{\alpha\beta }$ = - $\frac{1}{3}$

Hence the required equation is

x² + $\frac{5}{6}$ x - $\frac{1}{3}$ = 0 or

6x² + 5x - 2 = 0 ( multiplying through by 6 )

Which of the following represents a positive number?

Trava [24]

Answer: OPTION C

Step-by-step explanation:

A positive number must be greater than (>) 0, so lets check which fits this condition.

--------------------------------------------

7.09+(-7.28)=-0.19 NEGATIVE

-12+11.5=-0.5 NEGATIVE

-4.8-(-6.1)=1.3 POSITIVE

-21-(-18.5)=2.5 NEGATIVE

--------------------------------------------

C represents positive number

Hope this helps!! :)

What is the equation for the line of best fit for the following data? Round the slope and y intercept of the line to three decim

vesna_86 [32]

The line of best fit is given by the equation y = 1.56x - 4.105

<h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change (slope) and b is the y intercept.

Plotting the points on a graph using geogebra online tool:

The line of best fit is given by the equation y = 1.56x - 4.105
