A city manager made a scatter plot of number of retail stores in a certain cirty over years. The scatterplot had a trend like with an equation of y=11x+12, where y is the total number of retail stores and X is the number of years since 1990. Mark and his family moved to a city in 1997. How many retail stores were their in 1997

There were 89 retail stores in 1997.

Step-by-step explanation:

Hi, to answer this question, first, we have to calculate the number of years since 1990(x).

1997-1990 = 7 years

Now, we simply substitute x=7 (years) in the equation given

y=11x+12

y=11(7)+12

y=77+12

y = 89 retail stores

There were 89 retail stores in 1997.

Feel free to ask for more if needed or if you did not understand something.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

4x and 6y

im not sure though
