Question

Find the solution(s) to the following system of equations:

y = 5

y = 3x - 4

Write answer as an ordered pair(s). Separate by a comma if more than one solution.


what is the x ordered pair

Answer 1

If y = A and y = B, then set A = B, solve for the X value

Answer 2

5 = 3x - 4

Answer 3

I got -1 ?

Answer 4

5 + 4 = 3x - 4 + 4

9 = 3x

x = 3


y = 5 is already given

Answer 5

the answer that I have is 3,5 but it's wrong

Answer 6

the point (3,5) is where the two lines intersect

Answer 7

I got 239?

Answer 8

how is (3,5) wrong though? It does satisfy both equations

Answer 9

the y axis is right but the x axis isn't

Answer 10

are you trying to put this in a computer test

Answer 11

could be mymathlab stuff ?!
that was horrible when I took Calculus II

Answer 12

you said you put 3,5 try (3,5)

Answer 13

I have in like that (3,5)

Answer 14

some sites are so super sensitive even though you have the right answer.

Answer 15

what site are you using @Aliypop ?

Answer 16

It's called Moodel

Answer 17

The y-coordinate is correct. Check the x again by graphing the system. thats the reply my teacher left

Answer 18

omg..... that means we have to use the graphing method

Answer 19

I would put a side note....
yo man solving for x helps too ...there's more than one method to solve a problem as long as it doesn't break math rules geez.

Answer 20

so I guess we have to graph y = 5 and y = 3x-4 -_-

Answer 21

okay

Answer 22

so y = 5 means that our x is set at 0 so draw a horizontal line at (0,5)

Answer 23

okay

Answer 24

and then for y = 3x-4 we have to let x be any number like x = 0,1,2,3 solve for y and plot points

Answer 25

ok

Answer 26

that's about it.. if x = 3 there should be intersection... honestly... more than one method works... wow.

Answer 27

I'm just peeved at what your teacher wrote like... dude come on

Answer 28

my teacher isn't the best I'm serious

Answer 29

yeah it already shows smh

Answer 30

this is just a summer school class and I'm almost done I'm ahead of the class and she go upset about it

Answer 31

LOL! XD

Answer 32

what was her reason to be upset at you though?

Answer 33

because 1 I was far ahead of the class , I came from a online home school so I'm usually ahead of my classes anyways

Answer 34

that's good.

Answer 35

getting ahead is the best thing ever...even I got blasted for being ahead in my computer classes but I just didn't care about what my professors said.

Answer 36

but i'm going to public high school they want me to finish on pace with the rest, also is the answer 0,5

Answer 37

hmmm... if we're going to use the graphing method we have to graph y = 5 which is a horizontal line. Since x isn't given, it's already 0. so we have a horizontal line at (0,5)
then for y=3x-4 we let x = 0,1,2,3... and solve for y to get points. we then use that information to graph until we find the point of intersection with is (3,5)

Answer 38

it is supposed to be (3,5) that's the point of intersection.... but since it's the graphing method instead of substitution method then we graph 2 lines.

Answer 39

did you graph y = 5 and y = 3x-4 ?

Answer 40

I had gotten -2

Answer 41

oh were you solving for y =3x-4 by letting x = 0,1,2,3 ?

Answer 42

I got -3 with zero

Answer 43

wait... for y = 3x-4 (just focus on that equation...nevermind the y =5)
if x = 0 then y = -4...so we have one point (0,-4)
