Suppose the sales of a particular brand of appliance are modeled by the linear
function s(x) = 200x + 3700, where s(x) represents the number of sales in year x, with x = 0
corresponding to 2002. use this model to predict the number of sales in 2020.

7300 sales in the year 2020

Step-by-step explanation:

Notice that if the year 2002 represents the year zero, then the years 2020 is:

2020-2002=18 (year number 18).

Now we can simply use the given expression for year "x"  to evaluate what the sales would be in the 18th year:

Therefore the number of sales would be 7300 in the year 2020 according to this model.

which expression represents the approximate length of bc?

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
