<u>Algebra I</u>

  • Terms/Coefficients
  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

4x + 3y = 37

y = x - 4

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                                                                                                4x + 3(x - 4) = 37
  2. Distribute 3:                                                                                                    4x + 3x - 12 = 37
  3. Combine like terms:                                                                                       7x - 12 = 37
  4. [APE] Add 12 on both sides:                                                                           7x = 49
  5. [DPE] Divide 7 on both sides:                                                                        x = 7

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

  1. Define equation:                                                                                             y = x - 4
  2. Substitute in <em>x</em>:                                                                                                y = 7 - 4
  3. Subtract:                                                                                                           y = 3

Step-by-step explanation:

so they used  a total of  560  units

we are next told that if the units of usage are 360 or less use the 1st formula, but there is morn than 360 units in the given amount so use the 2nd formula

0.1(x-360+54)

0.1(560-360) + 54 = monthly bill

2. Ramone and his wife had $72,380.90 in combined gross income in 2010. They had $8,295.00 in various adjustments and deductions
MAVERICK [17]
Let x = taxable income = difference of gross income and deductions T = income tax paid = amount sent to the government Use the "filing jointly" chart on the right side. You'll use the second row of that chart since subtracting $72,380.90-$8,295.00 leads to a value between 16750 and 68000. That second row turns into this equation T=1675+0.15(x-16750<span>) w</span>here <span>16750<x≤68000</span>
