Write a quadratic equation given the roots -1/3 and 5, show your work

Travka [436]

$\boxed{(x - a)(x - b) = 0}$

The equation above is the intercept form. Both a-term and b-term are the roots of equation.

$x = - \frac{1}{3} \\ x = 5$

These are the roots of equation. Therefore we substitute a = - 1/3 and b = 5 in the equation.

$(x + \frac{1}{3} )(x - 5) = 0$

Here we can convert the expression x+1/3 to this.

$x + \frac{1}{3} = 0 \\ 3x + 1 = 0$

Rewrite the equation.

$(3x + 1)(x - 5) = 0$

Simplify by multiplying both expressions.

$3 {x}^{2} - 15x + x - 5 = 0 \\ 3 {x}^{2} - 14x - 5 = 0$

Answer Check

Substitute the given roots in the equation.

$3 {(5)}^{2} - 14(5) - 5 = 0 \\ 75 - 70 - 5 = 0 \\ 75 - 75 = 0 \\ 0 = 0$

$3( - \frac{1}{3} )^{2} - 14( - \frac{1}{3}) - 5 = 0 \\ 3( \frac{1}{9} ) + \frac{14}{3} - 5 = 0 \\ \frac{1}{3} + \frac{14}{3} - \frac{15}{3} = 0 \\ \frac{15}{3} - \frac{15}{3} = 0 \\ 0 = 0$

The equation is true for both roots.

Answer

$\large \boxed {3 {x}^{2} - 14x - 5 = 0}$

Jaime has 5 over 11 spaceof a project completed while Tim has finished 7 over 13 spaceof the same project.

lina2011 [118]

Tim has completed greater amount of work and overall they have completed 142/143 of the project work

Step-by-step explanation:

Given

Work completed by Jaime = j = 5/11

Work completed by Tim = t = 7/13

a. Who has completed the greater amount of work?

In order to see that we have to convert the fractions in decimal

So,

j = 5/11 = 0.45

t = 7/13 = 0.53

As we can see that the decimal for Tim's work space is large, Tim has completed greater amount of work

b. How much of the project have they completed together? Show your work.

We have to find the total work done by them

$Total\ work = j + t\\= \frac{5}{11} + \frac{7}{13}\\=\frac{65+77}{143}\\=\frac{142}{143}$

Hence,

Tim has completed greater amount of work and overall they have completed 142/143 of the project work
