The sum of a number and its reciprocal is 13/6. find the number
iris [78.8K]
Suppose the number is x, its reciprocal is 1/x
x+1/x=13/6
(x^2+1)/x=13/6
6(x^2+1)=13x
6x^2-13x+6=0
(3x-2)(2x-3)=0
x=2/3 or x=3/2

A year has 365 days, and a day has 24 hours. If an hour has 60 minutes and a minute has 60 seconds, how many seconds are there i
motikmotik
Ok, so we need to take 60 x 60.  That gives us 3600, which is the amount of seconds in 60 minutes.  Then we need to take 3600 x 24, to figure out the number of seconds in 24 hours (1 full day).  That gives us 86,400.  Finally, we take 86400 x 365, to determine how many seconds are in 1 full year (365 days).  That gives us the answer of <span>31536000.  Hope this helps!</span>

Write a linear equation that contains the ordered pair shown in the table below:
Amiraneli [1.4K]

Answer:

y=2x-4

Step-by-step explanation:

Let the equation of line is y=mx+b, where m is the slope of the line.

It passes through (-5,-14),(-2,-8)\ and\ (1,-2).

(<em>Slope of the line</em> joining (x_1,y_1)\ and\ (x_2,y_2)=\frac{y_2-y_1}{x_2-x_1})

Hence slope of the given line

m=\frac{-8(-14)}{-2-(-5)}=\frac{-8+14}{-2+5}=\frac{6}{3}=2

Equation of line is: y=2x+b

The line passes through (1,-2)

-2=2\times 1+b\\b=-2-2\\b=-4

Check if (-5,-14) is on the line y=2x-4

L.H.S.=-14\\R.H.S.=2\times (-5)-4=-10-4=-14\\L.H.S.=R.H.S.

Hence line passes through (5,-14).

Check if (-2,-8) is on the line y=2x-4

L.H.S.=-8\\R.H.S.=2\times (-2)-4=-4-4=-8\\L.H.S.=R.H.S.

Hence line passes through (-2,-8).
