Question

i have been stuck on this for over an hour please can i get some help i will give a medal

Answer 1

Explain why the x-coordinates of the points where the graphs of the equations

Answer 2

\[y=2^{-x}\]

Answer 3

and \[y=4^{x+3}\]

Answer 4

@kale01

Answer 5

intersect are the solutions of the equation \[2^{-x} =4^{x+3}\]

Answer 6

do you think you can help

Answer 7

@noneyabusiness would you happen to know?

Answer 8

sorry I have no idea. could you insert a graph? I am a visual person

Answer 9

it was a word problem @Xmoses1

Answer 16

ummm let me figure it out giveme a sec k

Answer 17

I dont really understand the question lol

Answer 18

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 2^{-x} and y = 4^{x + 3} intersect are the solutions of the equation 2^{-x }= 4^{x + 3}. that is all i have on the question

Answer 19

ohhh now i see lol

Answer 20

If the two functions are mapped in the same domain then you can solve them simultaneously

Answer 21

thats correct

Answer 22

told you she could help!

Answer 23

ok i understand that part of it im strugliing to find the variable

Answer 24

or he

Answer 25

Answer 27

uhhhhhhhhh

Answer 28
