What is (2)(-3)(-4)
lawyer [7]

Answer:

No, No, Yes, Yes.

Step-by-step explanation: 2 times -3 = -6. -6 times -4 = 24.

So, with that said, the first one multiples out to -24.

The second multiplies out to again -24.

12 times 2 = 24.

A negative and a negative multiply to become a positive, so -4 times -6 = 24.

They want me to put something here and the question is the picture
arsen [322]

Answer:

D. (1, -2)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

5x - 2y = 9

3x + 4y = -5

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

10x - 4y = 18

3x + 4y = -5

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Add to equations together:                    13x = 13
  2. Divide 13 on both sides:                          x = 1

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

  1. Define:                              3x + 4y = -5
  2. Substitute in <em>x</em>:                 3(1) + 4y = -5
  3. Multiply:                            3 + 4y = -5
  4. Isolate <em>y </em>term:                  4y = -8
  5. Isolate <em>y</em>:                           y = -2

And we have our final answer!
