Frank devised a formula for his catering business that calculates the number of meatballs he needs to prepare. The formula is m=
NeX [460]
So if m=4a+2c is your equation then all you have to do is plug in the numbers.

So you then get m=4(25)+2(7), for 25 adults and 7 children.

Then you solve.  m=100+2(7)
                           m=100+14
                            m=114
So Frank will need 114 Meatballs for the party of 25 adults and 7 children
 Hope this helps! And if you need anything else just ask :)

Vivian found data about her city's population and made a scatter plot the equation of the linebbest fit for. Her data is p= 637.
Andre45 [30]

Answer:

annual growth rate m = 637.5 people / year

Step-by-step explanation:

Solution:-

- The scatter plot displaying the city's population was modeled by a linear equation of the form:

                               y = m*x + c

Where, m and c are constants.

- The scatter plot displayed the following relation of the city's population (p):

                               p = 637.5*t + 198,368.1

Where, p : The population in t years after after 1990

            t : The number of years passed since 1990.

- The slope of the graph "m = 637.5" denotes the rate of change of dependent variable with respect ot independent variable:

                             dp / dt = m = 637.5

- So the rate of change of population per unit time t since 1990 has been constant with a an annual growth rate m = 637.5 people / year
