<u>Answer </u><u>with</u><u> step by step explanation</u>

(1)(3 {x}^{2}  + 2xy + 7) - (6 {x}^{2}  - 4xy + 3) \\ 3 {x}^{2}  + 2xy + 7 - 6 {x}^{2}  + 4xy - 3 \\  =  - 3 {x}^{2}  + 6xy + 4

(2)9 {x}^{2}  - 2x + 3 - (4 {x}^{2}  + 7x - 5) \\ 9 {x}^{2}  - 2x + 3 - 4 {x}^{2}  - 7x + 5 \\  = 5 {x}^{2}  - 9x + 8

(3) {x}^{2}  - 5x + 6 \\  {x}^{2}  - 3x - 2x + 6 \\ x(x - 3) - 2(x - 3) \\ (x - 2)(x - 3)

Evelyn has $524.96 in her checking account. She must maintain a $500 balance to avoid a fee. She wrote a check for $32.50 today.
cupoosta [38]

A linear inequality to represent the algebraic expression is given as 492.46 - x ≥ 500

<h3>Linear Inequality</h3>

Linear inequalities are inequalities that involve at least one linear algebraic expression, that is, a polynomial of degree 1 is compared with another algebraic expression of degree less than or equal to 1.

In this problem, her minimum balance must not decrease beyond $500 or she will pay a fee.

where

  • x = withdrawals

The inequality to represent this can be written as

524.96 - 32.50 - x ≥ 500

Simplifying this;

492.46 - x ≥ 500

The linear inequality is 492.46 - x ≥ 500
