Answer:  Letter Choice ( B):   -x^2   -  4x  +  7

Step-by-step explanation:

( 4x^2   -  7x  +  9 )   -  (  5x^2   -  3x  +  2 )

Remove Parentheses:  (a)  =  a

4x^2  -  7x  +  9  -  ( 5x^2  -  3x  +  2 )  

-   ( 5x^2  -  3x  +  2 ):     - 5x^2  +   3x  -  2

Simplify:

   4x^2  -  7x   +  9   -   5x^2   +   3x   -  2

Answer:  

Letter Choice ( B ):

 -X^2    -    4x    +     7

Show the steps you used to solve<br> 4x + 2y = 8<br> 5x - 3y = 4
Mekhanik [1.2K]

Answer:

-0.2

Step-by-step explanation:

Simplifying

5x = 3y + -4

Reorder the terms:

5x = -4 + 3y

Solving

5x = -4 + 3y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '5'.

x = -0.8 + 0.6y

Simplifying

x = -0.8 + 0.6y
