Answer:

x = 36

y = 37.95

Step-by-step explanation:

By geometric mean property:

{12}^{2}  = 4 \times x \\  \\ 144 = 4 \times x \\  \\ x =  \frac{144}{4}  \\  \\ x = 36 \\  \\

By Pythagoras Theorem:

{y}^{2}  =  {12}^{2}  +  {x}^{2} \\  \\  {y}^{2}  =  {12}^{2}  +  {36}^{2}  \\  \\  {y}^{2}  = 144 + 1296 \\  \\  {y}^{2}  = 1440 \\  \\ y =  \sqrt{1440}  \\  \\  y = 37.95

G(x)=2x-2 <br> f(x)=x^2+3x <br> find (g of f)(2+x)
Bumek [7]

Answer:

Step-by-step explanation:

G(f(2+x))=g(2+x)^2+3(2+x)=2(2+x)^2+3(2+x)-2=2(4+4x+x^2)+6+3x=8+8x+2x^2+6+3x=2x^2+11x+14

Find the solution of the system by graphing
zvonat [6]

Answer:

x = -2

y = -1

(-2, -1)

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
  • Solving systems of equations by graphing

Step-by-step explanation:

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

y = x + 1

3x + 3y = -9

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                              3x + 3(x + 1) = -9
  2. Distribute 3:                                   3x + 3x + 3 = -9
  3. Combine like terms:                     6x + 3 = -9
  4. Isolate <em>x</em> term:                               6x = -12
  5. Isolate <em>x</em>:                                        x = -2

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

  1. Define original equation:                    y = x + 1
  2. Substitute in <em>x</em>:                                     y = -2 + 1
  3. Add:                                                      y = -1

<u>Step 4: Graph systems</u>

<em>Check the solution set.</em>
