Answer:

<u>The average price of a new home in 2000 was $ 268,927 (rounding to the next dollar)</u>

Step-by-step explanation:

Let's find out the average price of a new home in 2000, this way:

x = Average price of a new home in 2000

Increase rate = 77% = 0.77

476,000 = Average price of a new home in 2016

2. What was the average price of a new home in 2000?

x + 0.77x = 476,000

1.77x = 476,000

x = 476,000/1.77

<u>x = 268,927 (rounding to the next dollar)</u>

Answer: 0.1 or 1/10

Step-by-step explanation:

\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \:1\frac{1}{5}

1\frac{1}{5}=\frac{6}{5}

\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \frac{6}{5}

  \frac{3}{4}-\frac{2}{3}    =\frac{9}{12}-\frac{8}{12}

=\frac{1}{12}

\frac{6}{5}\cdot \frac{1}{12}

Cross, cancel common factor

\frac{1}{2}\cdot \frac{1}{5}

=\frac{1}{10}

PLEASE HELP! I’m struggling with each part any help will be amazing

Answer:

<u>slope:</u> -5/2

<u>y-intercept</u>: (0, 2)

<u>Linear function</u>: y = -5/2x + 2

Step-by-step explanation:

Given points (-2, 7) and (2, -3):

Use these points to solve for the slope of the line using the formula:

m = (y2 - y1)/(x2 - x1)

Let  (x1, y1) =  (-2, 7)

      (x2, y2) =  (2, -3)

Substitute these values into the equation:

m = (y2 - y1)/(x2 - x1)

m = (-3 - 7) / [2 - (-2)]

m = -10/ (2 + 2)

m = -10/4 = -5/2

Therefore, the  slope of the line in reduced form is m = -5/2.

The y-intercept is the <u>y-coordinate</u> of the point (0, <em>b</em>) where the graph of the linear equation crosses the y-axis of the Cartesian grid. The y-intercept is also the value of y when x = 0.

To solve for the y-intercept, use one of the given points (2, -3) and the slope (m = -5/2), and substitute their values into the slope-intercept form:

y = mx + b

-3 = -5/2(2) + b

-3 = -5 + b

Add 5 to both sides to solve for the y-intercept, b:

-3 + 5 = -5 + 5 + b

2 = b

Given the value of b = 2, it means that the y-intercept is (0, 2).

Therefore, given the slope of -5/2, and the y-intercept, b = 2:

The linear equation in slope-intercept form is: y = -5/2x + 2
