Medal and Fan! ;)

Answer 1

What is your question.

Answer 2

There it is

Answer 3

So hard! Don't understand how to solve

Answer 4

Thank you for taking a look, I'm in deep trouble if I don't get this assignment in and I don't know where to start

Answer 5

A.

y=2^-x
y=4^x+3

by start y=y so than you need make the right side equal too and see what will get for x

do you can solve it for x ?

Answer 6

I think I know part A, which would be: The solution would be where the lines intersect because the point where the intersect would represent a point that provides solutions for both sets of equations. however Part B and Part C I am lost

Answer 7

2^-x = 4^x+3 do you have any idea for how you solve it ?

Answer 8

No, I haven't done that lesson in a while, I would assume that you get the 2 x variables on one side.

Answer 9

because on the left side there is 2 with an exponent so how can you rewrite the right side to be there 2 with an exponent same to the left side ?

Answer 10

You multiply the left side by 2 and the 2 variables cancel out?

Answer 11

please concentrate just to the right side now please

how can you rewriting the 4^x+3 so that being 2 on an exponent ?

Answer 12

I don't know how to make the exponent 2, I can turn the Base, which is 4, in to 2 simply by multiplying it by one half.

Answer 13

no

for example

9^(x+2) = 3^2(x+2)

are these equales ? so than yes please justifie me why ?

Answer 14

because 3 to the second power is 9

Answer 15

exactly so just you need using these property in case of your exercise too - ok. ?

Answer 16

How does this help me solve the problem

Answer 17

I just don't see how things fit, sometimes I have trouble with that.

Answer 18

4^x+3 = 2^?

Answer 19

use exactly what i have wrote to you above

Answer 20

hope you know that 4=2^2

Answer 21

so than 4^x+3 = 2^2(x+3) yes ?

Answer 22

Does this apply to part A?

Answer 23

so than this will be on the right side

and now what is on the left side ?

Answer 24

How does this relate to part A?

Answer 25

Not questioning your help I'm just confused

Answer 26

but than you check what above you have wrote so you have said me that part A you know it

Answer 27

Well it says to Explain how they are solutions when they intersect, it seems like they're looking for an explanation.

Answer 28

ok. so than you try graphing two lines for eaxmple with coordinates (3,0) and (5,0)
i said 0 just for you can see it more easy - being the point origo - of the axe x and y - ok.?

so than you graph these lines - looke it please beacuse are y coordinates the same 0 and 0 so this mean that in this point these lines will intersect sure

sorry but i think that in an other example i dont explain to you more easy

do you understand it now ?

Answer 29

so from this result that where y=y these lines will intersect sure - this is for part A

for part B - check please what i have clarified with you above

Answer 30

are you here ?

Answer 31

Yes

Answer 32

Answer 33

@jhonyy9

Answer 34

Omg, jerk

Answer 35

do you understand what i have wrote above ?

Answer 36

for part A ?
