Since beth was born, the population of her town has increased at a rate of 850 people per year. on beth 9ths birthday, the total population was nearly 307,650.write and solve a linear equation on beths 16th birthday.

Equation: x = 850y + 300,000

population on beth's 16th birthday: x= 313, 600

Step-by-step explanation:

If "x" is the population when beth has "y", then

x = 307,650 + 850(y-9)

The population in y years is 307,650 plus the number of years that has pased since she had 9 year: (y-9) multiplied by 850 wich is how much the population increases  in a year.

We can simplify the problem eliminating the parenthesis:

x = 307,650 + 850y - 850*9

x = 850y + 300,000

Thus, for the 16th birthday

y= 16

x = 850(16) + 300,000

x= 313, 600

the 3rd option is right

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
