When 9 is subtracted from the square of a number, the result is 8 times the number. find the negative soulution. plz fast

The negative solution  k = -1 is the desired solution.

Step-by-step explanation:

Let the given number = k

So, according to the question:

or,

Now, solving this quadratic equation, we get

or, k ( k-9) + 1 (k-9) = 0

⇒( k-9)(k+1)  = 0

or, ( k-9)  = 0 , or (k+1)  = 0

⇒  k  = 9  or  k  = -1

Since we only want the negative solution , the k = -1 is the desired solution.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y
