Between 1990 and 1999, the number of movie screens in the united states increased by about 1500 each year. in 1996, there were 29,690 movie screens. write an equation of a line in slope-intercept form, to find the total number of screens y for any year x.

Step-by-step explanation:

Write an equation of a line in slope-intercept form, to find the total number of screens y for any year x

we know that

The linear equation in slope intercept form is equal to

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

Let

x ----> the number of years between 1990 and 1999

y ----> the number of movie screens in the United States

In this problem we have that

The unit rate or slope is equal to

we have the ordered pair

(6,29,690)

The x-coordinate is 6 because

1996-1990=6 years ---> is the number of years since 1990

substitute the given values in the equation

Solve for b

The linear equation is

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
