Question

Can someone help me with a few pre-algebra questions? I will give medals

Answer 1

can you please write them here

Answer 2

do you want a graph

Answer 3

Consider the following system of equations:

y = -x + 2
y = 3x + 1

Which description best describes the solution to the system of equations?
Line y = -x + 2 intersects line y = 3x + 1.
Lines y = -x + 2 and y = 3x + 1 intersect the x-axis.
Lines y = -x + 2 and y = 3x + 1 intersect the y-axis.
Line y = -x + 2 intersects the origin.

Answer 4

Just which answer is it please :)

Answer 5

of course

Answer 6

They have to intersect each other.

Answer 7

So which one is it?

Answer 8

i think either the first or third

Answer 9

@allibear2012 We can't 'just answer it' It's against Open Study's Code-of-COnduct

Answer 10

its the first

Answer 11

A great way to do these is to graph it out, it will help visualize what's going on in the problem

Answer 12

@Starbucks Don't give answers, it's against the code of conduct.

Answer 13

Thanks! I have a few more :)

Answer 14

because its not directly on the x or y axis , neither the origin

Answer 15

@iambatman Shouldn't you do something?

Answer 16

You know, you spamming posts over and over isn't helping and is a bit annoying.

Answer 17

. . .

Answer 18

@Starbucks just gave a direct answer.

Answer 19

@Conqueror i gave reason , so calm down . its not gonna hurt anyone.

Answer 20

Consider the following pair of equations:

-x - y = -5
y = x + 1

If the two equations are graphed, at what point do the lines representing the two equations intersect?
(-2, 3)
(3, -2)
(2, 3)
(3, 2)

Answer 21

Spamming posts ?

Answer 22

i believe @Starbucks is right
however, @Conqueror is also right
do not break the rules
on the other hand, rules are made to be broken

Answer 23

@Starbucks Yes, it is..we need participation of the user..otherwise it is considered a direct answer.

Answer 24

well im so sorry if they say its okay to give a direct answer . like i said its not gonna hurt anyone.

Answer 25

Ok stop, you could directly message the user if you have a problem, you don't have to take over a post, it's fine if you say it once and move on, they get the message, but repeating it over and over again causes more problems, and is very distracting.

Anyways, @daphne101 would you like to graph this out and see what's going on?

Answer 26

To graph, set your equations up in y = mx+b form, this way you can get a clear picture of how the line looks.

Answer 27

So graphing the line, -x-y=-5, do some algebra and you'll get y = -x+5 which looks like this (+5 is the y - intercept, b in this case where the line crosses the y - axis). the other line is fairly easy to graph, try doing it.
