I just need to find out the last question that is in red. I don't know how to find the year when the median house values will be
Ganezh [65]

Answer:

1924.3

Step-by-step explanation:

Ok

You need to write an expression for the change in value

the change is linear, so you will get a line equation y = mx + b

y-axys : value

x-axys : years

New Hampshire:

Slope = \frac{133300-37600}{2000-1950} = 1914

the y-intercept will be 37600 because you can assume that 1950 = 0, and 2000 = 50

y = 1914*x + 37600

Massachussets:

Slope = \frac{185700-55400}{2000-1950} = 2606

Same as above, the y-intercept is 55400

y = 2606*x + 55400

Now you need to equal the value for both and find the year "x"

1914x + 37600 = 2606x + 55400

- 692x = 17800

x = -25.7

Since i considered x = 0 to be 1950; the actual year is 1950 - 25.7 = 1924.3

Example problems for area
xenn [34]

Answer:

Example 1.

A square with side lengths of 5.

5*5 = 25.

So the area would be 25 units ^2

Example 2.

A rectangle with a length of 9 and a width of 4

9*4 = 36

So the area is 36 units ^2

Name the property the equation illustrates.<br> (ab)3 = a (63)<br> Accociative Property of addition
Delvig [45]
<h3><u>Question:</u></h3>

Name the property the equation illustrates

(ab)3 = a(b3)

A. Commutative property of addition

B. Associative property of Multiplication

C. Associative Property of Addition

D. Inverse Property of Multiplication

<h3><u>Answer:</u></h3>

Associative property of Multiplication

<h3><u>Solution:</u></h3>

From given equation

(ab)3 = a(b3)

We have to find the property used here

We find the brackets are interchanged

So here, given is a multiplication equation

Therefore, Associative property of Multiplication  is used

<h3><u>Associative property of Multiplication:</u></h3>

This property says that when we are multiplying it does not matter where you put the parenthesis

The result will be same wherever we put the parenthesis in multiplying two or more numbers

Which means,

a \times (b \times c) = (a \times b) \times c

Therefore, from given,

a \times (b \times 3) = (a \times b) \times 3

Thus associative property of multiplication is used
