Solve this system by elimination 10x+6y=14 -x-6y=-23

Mathematics
1 answer:
ludmilkaskok [199]2 years ago
8 0

Answer:

(-1, 4)

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>

10x + 6y = 14

-x - 6y = -23

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Add 2 equations together:                    9x = -9
  2. Divide 9 on both sides:                          x = -1

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

  1. Define original equation:                    -x - 6y = -23
  2. Substitute in <em>x</em>:                                     -(-1) - 6y = -23
  3. Multiply:                                                1 - 6y = -23
  4. Subtract 1 on both sides:                     -6y = -24
  5. Divide -6 on both sides:                      y = 4

Simplify. 5(22 - 9 · 2) - 2( 3 · 2 4) 7 <br> a.-99 <br> b.-83 <br> c.-75 <br> d.-71
Pachacha [2.7K]
Not completely sure on the symbols, but I think it is 5 x ( 22 - 9 x 2 ) - 2 ( 3 x 2 x 4 ) x 7 = 136. It doesn't really match the answers, so my advice is that you use a calculator for this one, or as the person/teacher who gave you the problem how to solve it.

What is the scientfic notation of 0.05
vredina [299]

Answer:

5×10⁻²

Step-by-step explanation:

  • Move the decimal so there is one non-zero digit to the left of the decimal point.
  • The number of decimal places you move will be the exponent on the 10. a.  If the decimal is being moved to the right, the exponent will be negative.

        b.  If the decimal is being moved to the left, the exponent will be positive.

  • Therefore. The answer is 5×10⁻²

In triangle abc, AC=15 BC=11 and m
Oksana_A [137]

Answer: 10

Step-by-step explanation:

In a right angle triangle

Hypothenus ^2= opposite ^2+ adjacent ^2

According to a diagram below

Hypothenus =15

Opposite =?

Adjacent =11

Substitute for the values

15^2=11^2+opp^2

Opp^2=15^2-11^2

0pp^2= 225-121

Opp2=104

Opp= square root of 104

Opp= 10.2

Opp= ~10
