Question

Help me with this last question I really need help i give medal and i will fan

Answer 1

thats a hard question man

Answer 2

omg

Answer 3

why did ibbutibbu put that ?

Answer 4

can you put in the equation

Answer 5

ehh

Answer 6

@ganeshie8

Answer 7

i cant does this

Answer 8

@Compassionate @mathmale

Answer 9

@driftracer305 please help them

Answer 10

Any "solution" will be a point, a point that's on the straight line given by 5x-y=8.

Go ahead and find one such point. Arbitrarily let x=1. Find y. Write these two coordinates in the form (x,y).

Answer 11

im confused

Answer 12

there can be a number of solutions............ so u can just plugging with any numbers u like in part A...... start with 1 and keep going @geekfromthefutur

Answer 13

You are given 5x-y=8. Replace that x by '1'. What do you get?

Answer 14

My '1' is such an "any number u like.'

Answer 15

51-7=8

Answer 16

Excuse me, I should have asked you to "replace x with (1)." Please do that now. Then simplify 5(1).

Answer 17

5-8 = y = y = -3

Answer 18

5-8=-3

Answer 19

@driftracer305: If you look carefully, I'm trying to help our friend geek to solve this problem himself or herself. Kindly do NOT give away answers without the involvement of the person asking the question!

Answer 20

'geek': Yes. if x=1, y=-3. Write that point in the form (x,y) now, please.

Answer 21

OHHHHHH i think i get it

Answer 22

k @mathmale ........... sorry man.......

Answer 23

You may then choose a couple of other x values and find the associated y-values.

That takes care of Part B. Use material from our discussion to answer Part A.

Are you OK with Part C?

Answer 24

No i still dont get it the confusion is coming from the write the point in the form is wat is makin me stuck

Answer 25

All points are written in the form (x,y). The x represents the 'x-coordinate" of the point. The y repres. the "y-coordinate" of the point. If, as in this example, x=1 and y=-3, then the point is (1,-3).

choose 2 other x values. Find the corresponding y values. Than write the 2 points in the form (x,y), please.

Answer 26

Oh

Answer 27

So i can chose any number

Answer 28

for the x value

Answer 29

(2,-3) (3,-3)

Answer 30

Toss a die and use whatever number comes out on top as your x-value. Really: ANY number is fine.

Answer 31

If you choose x=2, then 5(x)-y=8 becomes 5(2)-y=8, or y=2. Check that. Do you agree or disagree? If you disagree, re-write the first point as (2, ? )

Answer 32

i agree i suck at math somtimes

Answer 33

Kindly don't say that...the least you can do for yourself is to say, "I can learn this just fine with a sufficient investment of time and effort."

If x=2, then y=2. Thus, 5(2)-2=8 becomes true.

Show how you got your 3rd point. Let x= 3. Where does that -3 come from? i'd like to see your work.

Answer 34

i picked a random number

Answer 35

You picked a random x-value, or you picked a random y-value? Pick a random x-value (NOT y-value) and use the given equation to calculate y.

Answer 36

x value i kept the y the same as the others

Answer 37

No. that equation governs the relationship between x and y.

Given x, you CALCULATE y.

or....

Given y, you CALCULATE x.

Choose x=5. Substitute that into 5x-y=8. Calculate y, please.

Answer 38

-3

Answer 39

When I say "substitute that into 5x-y=8, I mean the following:

Rewrite 5x-y=8 as 5(5)-y=8.

What is 5(5)?

Answer 40

5*5=25

Answer 41

or 1

Answer 42

Right. Then your 5x-y=8 becomes 25-y=8.

Please now subtract 8 from both sides. What do you get?

Answer 43

-25

Answer 44

Simplify: 25-8-y=8-8

Answer 45

0 or 9

Answer 46

Have to write the whole equation.

25-8 is 17.
25-8-y is 17-y.

Right side: 8-8 is zero.

Write the left side (from above) , followed by the '=' sign, and then the right side (from above).

Answer 47

So it 25-8 = 8-8

Answer 48

17-y=0, actually. Make certain you understand where that came from.

25-8 is 17.
25-8-y is 17-y.

Answer 49

You've dropped the 'y'. Can't do that.

Answer 50

o ok

Answer 51

25-8-y=8-8

becomes

17 - y = 0

Solve this for y, please.

Answer 52

y=17

Answer 53

Right. So, if x=5, y=17. Are you now OK with this, or have y ou questions about tghe process?

Answer 54

No i good

Answer 55

OK. So now you have 3 points that line on the line represented by 5x-y=8. OK?

You should list them as you answer this question.

I need to get off the 'Net pretty quickly. But do you have further questions about Parts A, B or C?

Answer 56

So for part a it is 5-8=-3 part b is (1,-3) 2,-3 and 5,-3 part c is 17-y=0 and y=17

Answer 57

Im just nailing it down to the answers

Answer 58

Part A: You need to represent ALL possible solutions of 5x-y=8. That equation alone does that. If you want to be fancier, you could solve that equation and obtain y=5x-8.

I am not going to check your results for Part B since we've discussed them in detail and you have our conversation to use to check your own results.

What about Part C?

Answer 59

3 points that line on the line represented by 5x-y=8.

Answer 60

Yes...that's what you now have for Part B.

Do you hve to do Part C? If so, what are your thoughts on that so far?

Answer 61

part c is (17,5)

Answer 62

No, sorry. You are to write an EQUATION similar to 5x-y=8 such that the two lines represented by these two equations never intersect.

Answer 63

25-8-y=8-8

Answer 64

"inconsistent" means / signifies that the two lines represented by your two different equations never intersect.

Your 25-8-y=8-8 is the same equation you started with, and thus could not be the answer.

Given 5x-y=8, you can obtain a new line that never intersects the given line simply by changeing the constant on the right.

Do that now, please.

Answer 65

Start with 5x-y=8. Throw out the 8 and choose some other number.

Answer 66

17- y=0

Answer 67

All you have to do is to modify the equation 5x-y=8 so that the number on the right is differnt from 8. Think of a number, any number, different from 8. What is it?

Answer 68

5x-y=4

Answer 69

Fine. Since 4 is different from 8, you have the equation of a line parallel to 5x-y=8. These two lines will never intersect. Thus, your system consissting of these two lines is "inconsistent." You're done.

Answer 70

Thx for you time mathmale to help me on this

Answer 71

My pleasure. Later!! Bye.
