Sales of automobiles worldwide continues to grow as emerging economies provide their citizens more purchasing power. in 2009, there were thousand new car sales in a region, and in 2014, this number increased to 66 thousand cars. assume that the relationship between time, x, and number of new cars sold, y, is a linear relationship. a.) write an equation describing the relationship between time and the number of new automobiles sold in the region. use ordered pairs of the form (years past 2009, number of automobiles sold). b.) use this equation to predict the number of new car sales in the region in the year 2019. a.) the equation describing the relationship is:
(type in slope-intercept form).

b.) in the year 2019, thousand new cars will be sold

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

5x+2x=49

7x=49

x=7. 35 apples

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
