One study found that the number of interest groups increased by what percentage between 1959 and 1995?
FrozenT [24]

Answer:

Percentage change in interest groups between 1959 (500) & 1995 (600) = 20%

Step-by-step explanation:

Percentage change = <u>Change ie (New - Old)  </u>  x 100

                                        Old value

Suppose -

Number of interest groups in 1959 = 500

Number of interest groups in 1995 = 600

Percentage change = [ (600 - 500) / 500 ] x 100

( 100 / 500 ) x 100 = 20%

Ye is riding home from a friend's house. After 5 minutes he is 4 miles from home, after 15 minutes Ye is 2 miles from home. Whic
Ad libitum [116K]

Answer:

y = -\frac{1}{5}x + 5

Step-by-step explanation:

Given

5\ minutes = 4\ miles

15\ minutes = 2\ miles

Required

Determine the equation

y represents distance

x represents time

So, the given parameters can be modeled (x,y) as:

(x_1,y_1) = (5,4)

(x_2,y_2) = (15,2)

First, we need to determine the slope of the function.

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{2 - 4}{15 - 5}

m = \frac{-2}{10}

m = -\frac{1}{5}

The equation can be determined using:

y - y_1 = m(x - x_1)

Where

m = -\frac{1}{5}

(x_1,y_1) = (5,4)

y - y_1 = m(x - x_1)

becomes

y - 4 = \frac{-1}{5}(x - 5)

Open bracket

y - 4 = -\frac{1}{5}x + 1

Solve for y

y = -\frac{1}{5}x + 1 + 4

y = -\frac{1}{5}x + 5
