<u>Algebra I</u>

  • Terms/Coefficients
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

y = -x + 1

2x + 3y = 6

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

<em>Substitution</em>

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

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

  1. Define equation:                     y = -x + 1
  2. Substitute in <em>x</em>:                        y = -(-3) + 1
  3. Simplify:                                   y = 3 + 1
  4. Add:                                         y = 4

Please Help! It is Pre-Calc and I need to know the answer!
Kisachek [45]

That's again the derivative at 2, so the answer is A. 4.  Hard way:

f(x)=x²

f(2)=4

f(2+h) = (2+h)² = 4 + 4h + h²

f(2+h) - f(2) = 4h + h²

(f(2+h)-f(2))/h = 4 + h

Limit is 4.

Answer:  A.  4
