<h2>Given↷</h2>

A system of equations

  • y= x-1
  • y= -2x+5
<h2>To find↷</h2>
  • The solution to the system of equations
<h2>Answer↷</h2>
  • (2,1)
<h2>Solution↷</h2>

y = x -1 _ _ _ _ _ _(1)

y=-2x+5_ _ _ _ _ _(2)

  • subtracting equation 2 from equation 1,

we get,

x -1 = y

-(-2x +5 = y)

__________

3x -6 = 0

3x = 6

x = 6/3

x = 2

___________

  • Plugging the value of x in equation 1,

y= 2-1

y= 1

  • hence, the solution of this system of equation is (2,1)

What is the factorization of 121b4 − 49? (11b − 7)(11b − 7) (11b + 7)(11b − 7) (11b2 − 7)(11b2 − 7) (11b2 + 7)(11b2 − 7)
Bingel [31]

Answer:

Step-by-step explanation:

121b^4 - 49 is a "difference of squares."

Formula for factoring a "difference of squares:"

 a² - b² =  (a - b)(a + b)

So:  rewrite your 121b4 - 49 as 11²b^4 - 7² = (11b²)² - 7²

                                                                  = (11b² - 7)(11b² + 7)

This answer matches the last of the four given answer choices.

Cross multiply and solve for x:

12x = 324

x = 27
