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

Solve and graph, showing your work.
Alika [10]
For the inequality y - 4 > -7, get y by itself by adding 4 to both sides. Now you have y > -3.
For the inequality y - 1 < 6, get y by itself by adding 1 to both sides. Now you have y < 7.

Graph the set y > -3 and y < 7. It should look like this:
