Answer:

(3, 3)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define Systems</u>

x + y - 6 = 0

x - y = 0

<u>Step 2: Rewrite Systems</u>

x + y - 6 = 0

  1. Add 6 on both sides:                    x + y = 6

<u>Step 3: Redefine Systems</u>

x + y = 6

x - y = 0

<u>Step 4: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Combine 2 equations:                     2x = 6
  2. Divide 2 on both sides:                    x = 3

<u>Step 5: Solve for </u><em><u>y</u></em>

  1. Define equation:                     x - y = 0
  2. Substitute in <em>x</em>:                        3 - y = 0
  3. Subtract 3 on both sides:       -y = -3
  4. Divide -1 on both sides:          y = 3

The sum of two trinomials is 7x2 - 5x + 4. if one of the trinomials is 3x2 + 2x - 1, then what is the other trinomial?
Margarita [4]

Answer:

  b.  4x^2 -7x +5

Step-by-step explanation:

When you know a sum and one of its contributors, you can find the other by subtraction. The other trinomial is ...

  (7x^2 -5x +4) - (3x^2 +2x -1)

  = (7 -3)x^2 +(-5 -2)x +(4 -(-1))

  = 4x^2 -7x +5 . . . . . matches B

Ron earns a 15% commission on his sales in addition to a $1500 monthly salary. Determine his monthly sales goal if he budgets $3
Anastasy [175]

Answer:

His monthly sales goal if he budgets $3750 as his monthly income is $15000.

Step-by-step explanation:

From the information given, the formula to calculate the salary that Ron earns would be:

Total salary=1500+0.15*(monthly sales)

Now, you can replace the total salary and he budgets $3750 as his monthly income and solve for the monthly sales:

3750=1500+0.15*(monthly sales)

3750-1500=0.15*(monthly sales)

monthly sales=2250/0.15

monthly sales=15000

According to this, the answer is that his monthly sales goal if he budgets $3750 as his monthly income is $15000.
