The population of a small town in northern california gradually increases by about 50 people a year. in 2010, the population was 8500 people. write an equation for the population of this city and find its estimated population in 2017. the estimated population in 2017 is

50 × 7 + 8500 = 8850

Step-by-step explanation:

Since 7 years have passed since 2010, you would multiply 7 times 50 and add the initial population of 8500

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

source:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
