Solve the following system algerbraically: y=-3(x-2) squared+4 y=-6x+16
pishuonlain [190]

y =  - 3(x - 2) ^{2}  + 4
y =  - 6x + 16
distribute the -3 and the square into the first equation
y =  - 3x ^{2}  + 12x - 8
y =  - 6x + 16
multiply the second equation by 2
y =  - 3x ^{2}  + 12x - 8
y =  - 12x + 32
add the equations together
y =  - 3x ^{2}  + 24
factor out -3
y =  - 3(x ^{2}  - 8)
factor inside parenthesis
y =  - 3(x +  \sqrt{8} )( x -  \sqrt{8})
refine
y =  - 3(x + 2 \sqrt{2} )(x - 2  \sqrt{2} )

Solve for x.<br> 7(1x - 3) = 4(x + 5)
alexandr1967 [171]

Answer:

x = 41/3

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

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

7(1x - 3) = 4(x + 5)

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

  1. Simplify:                                        7(x - 3) = 4(x + 5)
  2. Distribute:                                     7x - 21 = 4x + 20
  3. Subtract 4x on both sides:          3x - 21 = 20
  4. Add 21 on both sides:                  3x = 41
  5. Divide 3 on both sides:                x = 41/3

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    7(1(41/3) - 3) = 4(41/3 + 5)
  2. Multiply:                        7(41/3 - 3) = 4(41/3 + 5)
  3. Subtract/Add:               7(32/3) = 4(56/3)
  4. Multiply:                        224/3 = 224/3

Here, we see that 224/3 is indeed equivalent to 224/3. ∴ x = 41/3 is a solution to the equation.

And we have our final answer!
