Question

What is the solution to y = 2x – 1 for the replacement set x = {1.4}?

( , )

Answer 1

substitute 1.4 for x and solve

Answer 2

okay

Answer 3

When x = 1, y is 2*1 - 1.
When x = 4, y is 2*4 - 1.

I'm sure you can calculate those.

You're supposed to write this in set notation, so put those two results in the standard curly brackets { }

Answer 4

so

Answer 5

no you have to make it \[y=2(1.4)-1\]

Answer 6

okay

Answer 7

WAIT can you explay?

Answer 8

???

Answer 9

explan

Answer 10

explain*

Answer 11

sorry if I confuse @bohotness

Answer 12

okay so they gave you your x-value which is 1.4, so now you substitute x for 1.4 which would give you the equation for y which is 2(1.4)-1

Answer 13

okay

Answer 14

okay i got 1.8

Answer 15

okay so now you have your y-value

Answer 16

so 1.8,1.4

Answer 17

this is where i am not sure about... i don't know if you have to solve for x or if you're done... sorry

Answer 18

its okay

Answer 19

maybe @cookielate or @acxbox22 can help

Answer 20

so you already solved y right

Answer 21

Then you have to solve x so it could be like this >>> (x,y)

Answer 22

Are you confuse ??

Answer 23

yes i got y but what x?

Answer 24

X because its the solution

Answer 25

THANK YOU XD

Answer 26
