The square footage and monthly rental of 10 similar one-bedroom apartments yield the linear regression
Triss [41]

The footage of the room with a rental price of $1500 is 709 square foot

<h3>Linear equation</h3>

A linear equation is given by:

  • y = mx + b

where m is the rate of change, b is the initial value of y, y, x are variables.

Let y represent the monthly rental price and x represent the square footage. Given the equation:

y = 0.7752x + 950.25

For a rent of $1500:

1500 = 0.7752x + 950.25

  • x = 709 square foot.

The footage of the room with a rental price of $1500 is 709 square foot

-5+22=r-4+3r+5<br> I need help please and thank u
Brilliant_brown [7]

Answer:

r = 4

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

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

-5 + 22 = r - 4 + 3r + 5

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

  1. Combine like terms:                    17 = 4r + 1
  2. Subtract 1 on both sides:             16 = 4r
  3. Divide 4 on both sides:               4 = r
  4. Rewrite:                                        r = 4

<u>Step 3: Check</u>

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

  1. Substitute:                    -5 + 22 = 4 - 4 + 3(4) + 5
  2. Add/Subtract:               17 = 3(4) + 5
  3. Multiply:                        17 = 12 + 5
  4. Add:                              17 = 17
