first subtract 9 native both sides leaving you with -4x=48. Now, division -4 on both sides and get x=-12




You are watching: Find the value of x in the equation 9 – 4x = 57.

( 105 ) * ( 95 )

(100+5) * (100-5)

100*100 * (1 + 5/100) * ( 1 - 5/100)

10000 * ( 1 - 5/100 + 5/100 - 25/10000 )

- 5/100 + 5/100, castle cancel each other out come 0

10000 * ( 1 + 0 - 25/10000 )

10000 * ( 1 - 25/10000 )

10000 - 25*10000/10000

10000 - 25

given the 1 is a zero the p(x)=3x^4-x^3-8x^2+2x+4, element the polynomial completely, and also then list all that is zeros.
Divide ns over (x-1) with euclidian division we get the quotient:
*
Note the -2/3 is additionally roots of the over polynomial. Checking:
*
Dividing again through euclidian algorithm we gain the quotient:

A "tangent" come a line method the derivative. Girlfriend can distinguish the role as follows:
*
*
At a horizontal tangent, the derivative is same to 0. So, let"s collection it equal to 0, and also solve because that x. Remember, whenever act trigonometry in calculus, us assume we are beer-selection.coming in radians. So:
*
*
*
The values at which cos(x) amounts to -1 are π, and also then 3π, 5π and so on. You basically just keep adding 2π to the previous number and get the beer-selection.com. So, this can be composed as:
*
That will be your last beer-selection.com. You could write this together an unlimited series, but I simply didn"t desire to complicate it. So, if you desire one, i can offer you one.
