Solve the system of equations. (3x + 4y = 5) (2x - 3y = -8)
vovikov84 [41]

Answer:

the solution is (-1, 2)

Step-by-step explanation:

Let's solve the system

(3x + 4y = 5)

(2x - 3y = -8)

using the method of elimination by addition and subtraction.  Notice that if we multiply all terms of the first equation by 3 and all terms of the second by 4, y as a variable will temporarily disappear:

  9x + 12y = 15

  8x - 12y  = -32

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

 17x       = - 17, so x = -1.  

Replacing x in the second equation by -1, we get:

2(-1) - 3y = -8, or

2 + 3y = 8,

or 3y = 6.  Thus, y = 2, and the solution is (-1, 2).

Factorise (x-y)^2-(x-y)^3=?
bogdanovich [222]

Answer:

\left(x-y\right)^2\left(1-x+y\right)

Step-by-step explanation:

You factor out the common term first.

You should get the equation below.

\left(x-y\right)^2\left(1-\left(x-y\right)\right)

then you get rid of the negative inside\left(1-\left(x-y\right)\right)

and will be simplified to this.

\left(x-y\right)^2\left(1-x+y\right)

Roots of x^2+8x+9 by finding in quadratic formula
gladu [14]
The quadratic formula is -b + or - the square root of b squared - 4 times the a value and c value over 2a. So the roots would be -1.354249 and -6.645751. I believe these are the roots.
