Question

Which of the ordered pairs below satisfy the following equation?

Check all that apply.

y = 7x

A. (42, 7)
B. (84, 12)
C. (42, 6)
D. (6, 42)
E. (84, 14)
F. (12, 84)

Answer 1

Do you know how to do this? lol

Answer 2

no lol you might have to explain this too xD

Answer 3

or at least help me get on the right track

Answer 4

plug in bro try C

Answer 5

Hahaha It's easy
x is multiplied by 7 therefore, divide every x by 7

Answer 6

so then all the answers to the right are the ones to divide?

Answer 7

So when you for example divide 42 ( the x) by 7, it would equal y. SO 42 divided by 7 doesn't equal 7, so it's not A

Answer 8

y = 7x

your points are set up like (x,y)
so plug in your x points and your y points and see what comes out true.

(42,7)....x = 42 and y = 7
now we sub
y = 7x
7 = 7 * 42
I can tell you right now that this is not true.

Now just do the same for all the points and see which ones are true and these are your solutions

Answer 9

It would be C because 42 divided by 7 is 6
Do you see what i mean? Sorta?

Answer 10

Ok so when you divide for example the 84/7 it came out to be 12 and its (84,12) So would that also be right?

Answer 11

so whenever you divide it has to satisfy the equation so 84/7 has to come out 12 other wise it would be wrong right?

Answer 12

It is NOT C

Answer 13

Oh shoot, I messed up
Sorry

Answer 14

ok so was i wrong with B?

Answer 15

don't get your x's and y's mixed up

Answer 16

B is NOT a solution

Answer 17

Wait, it's D and F. They fit the equation. I apologize, I mixed up the x's and y's

Answer 18

just sub in your points (x,y) into the equation and see what comes out true.
It is D and F

Answer 19

Ok thanks so much!!

Answer 20

See...
D. (6,42)...x = 6 and y = 42
now sub
y = 7x
42 = 7(6)
42 = 42 (correct) therefore, it is a solution

Answer 21

Your welcome! Sorry i messed up there lol

Answer 22

lol its all good!!

Answer 23

lol...If I had $1 for every time I messed up, I would be rich. That is kinda sad to say.
