Question

Make tables to find the solution to 2−x = 4x + 3. Take the integer values of x only between −3 and 3

Answer 1

this isn't explaining this problem razor. Thank u, but this does not help me..

Answer 2

._. Waittttttttttttt

Answer 3

?

Answer 4

Is this the full question?

Answer 5

no its not. heres the full thing: Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 2−x and y = 4x + 3 intersect are the solutions of the equation 2−x = 4x + 3. (4 points)

Part B: Make tables to find the solution to 2−x = 4x + 3. Take the integer values of x only between −3 and 3. (4 points)

Part C: How can you solve the equation 2−x = 4x + 3 graphically? (2 points)

Answer 6

A. We have two lines: y = 2-x and y = 4x+3
Given two simultaneous equations that are both required to be true.. the solution is the points where the lines cross... Which is where the two equations are equal.. Thus the solution that works for both equations is when
2-x = 4x+3
because where that is true is where the two lines will cross and that is the common point that satisfies both equations.

Answer 7

Thats part A.

Answer 8

alright. reading it.

Answer 9

Make two tables, one for each expression. Input values between -3 and 3 (labeled as x since they are inputs) and write down the result under y (as the result would be the output). Remember, we are just looking for where these graphs intersect (have the same output for the same input).

Answer 10

so razor, the simplified version of this could very well be 'Because at that x point, they give the same output (y value).', correct?

Answer 11

Yep ._. and Shadow helped tew

Answer 12

alrighty thn lol. reading shadows now.

Answer 13

shadow, could i possible put them in desmos to do that or no?

Answer 14

I know that you can make tables in desmos, although I do not know how. Why do you wish to do so anyway?

Answer 15

because it says 'make tables' .-.

Answer 16

Is this online?

Answer 17

the question?

Answer 18

Online school

Answer 19

oh, yea. it is. y?

Answer 20

They don’t have a tool or something?

Answer 21

they have desmos on their homepage, which is didnt even notice until recently

Answer 22

Just do this:

Table 1
x: 1 y: 3
etc

Answer 23

I mean if you can upload files, you can try create them there, and then see if there is a download feature, or just use a screenshot tool.

Answer 24

yea. i will try the screenshot thing first lol.

Answer 25

Okay well do you know what to do regarding inputting x values and getting y values

Answer 26

apparently not bc i just put in the equation and this is what i got. nada.

Answer 27

1. You did not input the equation in correctly. There are no exponents.
2. That is not how you solve this problem...

Answer 28

2 - x
2 - (-2)
2+ 2 = 4

Table 1
x = -2, y = 4

Answer 29

Then input -2 into the other expression and start table two. Then go all the way to positive 2...

Answer 30

so i reput it in, taking away the exponents and putting them in normally and this is what i got:

Answer 31

That is not how you solve this. Maybe try read what I posted.

Answer 32

i read it but i still dont get it.. :/

Answer 33

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Shadow
2 - x
2 - (-2)
2+ 2 = 4

Table 1
x = -2, y = 4

Answer 34

Do you get what I did here?

Answer 36

I am doing that in what I quoted.

Answer 37

no, i dont get what u did that. where did the -2 come from and crap, i just dont get it...

Answer 38

im sorry im terrible at this kind of thing...

Answer 39

An integer is a whole number. I took a whole number between -3 and 3 and inputted it into the first expression to see what I would get.

Answer 40

oh. ok. im starting to get it now.

Answer 41

Input -2 for the other expression, and start Table 2.

Then keep inputting whole numbers til you get to 2

Answer 42

so -2, -1, 0, 1, and 2, are all your inputs

Answer 43

would it be 2 then?

Answer 44

what

Answer 45

i think im just gonna put in what i think best because this is just confusing me more and more. thank u for trying to help me tho. :)

Answer 46

Okay.
