If x-9 is a factor of x-5x-36 what is the other factor
dimaraw [331]
The other factor would be (x + 4). We can find this by using synthetic division. To do this, we must first find the divisor, which would be 9, if we let x - 9 equal to zero and solve for x. Then, for the dividend, we can use the coefficients and constant term values. 
<u>9</u>| 1  -5  -36
<u>         9  36</u>
     1  4  0
Therefore, the other expression (x + 9) would be (x + 4). Hope this helped!

Write a point slope equation for -5/7 using the coordinates (6,2)
sleet_krkn [62]

Answer:

(13, -3)

Step-by-step explanation:

slope = -5/7

(6,2)  

m = ( y2 - y1) / ( x2 - x1 )

-5/7 = ( y2 - 2) / ( x2 - 6 )

   

    -5 = y2 -2

        +2        +2

        -3 = y2


      7 = x2 - 6

    +6         +6

      13 = x2


Check answer again by log them in:

m = ( y2 - y1 ) / ( x2 - x1 )

m = ( -3 - 2 ) / ( 13 - 6 )

m = -5 / 7


I hope this helps!

The quartet  earn between $25 and $40 per hour.

so

If they play for 3 hours

then

($25*3)=$75

($40*3)=$120

the quartet will earn between  $75 and $120

Divide the money equally between the four members

$75/4=$18.75

$120/4=$30
