Hello there!

The number of people in different cities should be represented on a graph as Two-dimensional.

I'll explain why: The number of dimensions you need on a graph is equal to the number of variables that you are studying. In this case, you have two variables in the study:

1)The number of people
2)The city where they live

You'll need a two-dimensional graph with two axes in which one of the axes represents the number of people and the other axis represents the city. If you were also studying the age of those people, you'll need one more dimension to include this new variable.

Have a nice day!

HELP PLEASE Write the inequality that models the number granola bars (12) you need to buy.

Goshia [24]

The correct question in the attached figure

Let
x-------------> the number of granola bars
y-------------> the pounds of fruit

we know that

if 12 bars------------> cost $12
1 bars--------------> X
X=12/12---> x=$1
1 bar---------> cost $1

if 9 pounds of fruit----------> cost $36
1 pound-------------------> X
X=36/9--------> x=$4
1 pound -------> cost $4

expression for the total cost=(1)*x+(4)*y----------> x+4y
x=12
y=9
then
the total cost=12+4*9----- $48

an inequality that compares
the total cost with the amount you have to spend is
x+4y<=48

using a graph tool see the attached figure

the inequality that models the number of granola bars you need to buy is

x<=12 the solution for the number of granola bars is the interval [0,12]
