Question

Help for a medal and fan!!
The city of Phoenix, Arizona, has laid out their main city streets in a linear grid. Roads run north to south or east to west. Finding intersections of the streets is pretty easy, since every road is a straight line. Imagine if Phoenix has used only curved roads, or circular roads, or roads that bent and went off in different directions. Thinking of those roads in Phoenix as linear equations, we will now solve systems that have non-linear equations in them using graphs. These graphs will serve as your GPS to find the intersections of the “roads.”

Answer 1

Ask your teacher. Lol

Answer 2

? If your not going to help, please do not reply. I'm in serious need of help. I need to finish my flvs before july 10th to graduate and i still have 57 lessons to go. Thanks.

Answer 3

Well you better get to work and start searching google.

Answer 4

i have and i cant find the answer to this first part. I got the answers to these two questions
How can graphing be applied to solving systems of non-linear equations?
How can constraints be used to model a real-world situation?
But i have no idea how to do step one.

Answer 5

@Johnbc @Eli_Moses

Answer 6

When you have non linear equations and plot them, you can obtain the points where those functions intersect, so they are possible solutions.

Answer 7

Yeah i got that already. found that answer on google lol you too?

Answer 8

Yes.....lol

Answer 9

hahahaha

Answer 10

@Jhannybean can you help?

Answer 11

@jdoe0001 can you help?

Answer 12

@Johnbc @tgawade can you help me?

Answer 13

@Australopithecus can you help me?

Answer 14

@arris04 can you help me?

Answer 15

I feel like this question is not really complete, I dont see what it is asking for

Answer 16

That is what im saying. I dont get what it is asking. After it says that it says
After completing this lesson, you will be able to answer the following questions:

How can graphing be applied to solving systems of non-linear equations?
How can constraints be used to model a real-world situation?
Are those two questions what im suppose to answer? I'm so confused!

Answer 17

Is a graph provided?

Answer 18

no. Just that first paragraph and two questions that fallow.

Answer 19

Hint: For each x value, there is a corresponding Y value.

Answer 20

For the first question,

Well when you are solving a system of a linear equation you are just looking for an intersection between the two equations.

Think about it.

For the second question,

You can simply use a fixed domain and range to model a real world problem

Answer 21

i dont get that @Johnbc where did x and y come from?

Answer 22

so would this be the answer to # 1: When you have non linear equtions and plot them, you can obtain the points where those functions intersect, so they are possible solutions.

and

This for # 2: Constraints can be used to model, for example, variables that cannot be zero. For example, the usual conditions
x≥0;y≥0
for variables that represent quantities that cannot be less than zero (a physical example: absolute temperature in Kelvin) for # 2?

Answer 23

@Australopithecus

Answer 24

I suppose, those seem like fine answers.

Answer 25

It can also make it easier to analyze intersections like if you have a system of oscillating functions but yeah those answers make sense to me.

Answer 26

Okay. Thank you SOOOO much. I fanned you and gave you a medal. You rock man!

Answer 27

bro.. so what was the answers..
