Question

please help me, been stuck..will fan and medal...

Answer 1

Complete the table below to solve the equation 2.5x – 10.5 = 64(0.5x).

x f(x)= 2.5x – 10.5 g(x) = 64(0.5x)
2
3
4
5
6

Answer 2

ignore the question marks

Answer 3

Refresh and they'll go away :P

Answer 4

f(x)=2.5x-10.5 g(x)=64(0.5^x)

Answer 5

2 f(2)=2.5(2)-10.5 g(2)=64(0.5(2))

Answer 6

That's for the second line. then you do the same thing for the rest

Answer 7

Well first omplete the table below to solve the equation 2.5x – 10.5 = 64(0.5x).?
x f(x) = 2.5x – 10.5 g(x) = 64(0.5x)
2 -5.5 64
3 -2.5 96
4 -0.5 128
I think there is no solution for x > 0
0 -10.5 0
0.1
0.2
-0.3556 -11.3898 -11.3898

Let us try algebra. 2.5x – 10.5 = 64(0.5x) = 32x or 29.5x = -10.5 or x = -10.5/29.5 = -.03556

Answer 8

complete

Answer 9

you just copied and pasted that from yahoo answers

Answer 10

yeah lol

Answer 11

rip in pepperonies to me

Answer 12

but im busy so that will be the last time i do that

Answer 13

You just need to plug the number on the left in for the functions

Answer 14

well thats the problem

Answer 15

what's the problem? you take the numbers on the left and put them in for x

Answer 16

so the left column is the same thing but with like...f(3)? @wrstlr3232

Answer 17

yes

Answer 18

and then i just solve for the right side?

Answer 19

solve whats on the left for the right

Answer 20

so
3 2.5(3)-10.5 g(3)=64(0.5^(3))

Answer 21

correct. so if you look at here to help's answer for 2, he has -5.5.
f(2)=2.5(2)-10.5=-5.5

Answer 22

@wrstlr3232 read that latest message please

Answer 23

So, g(x)=64(0.5^x) turns into g(3)=64(0.5^3). Yes, you want f(3) for f(x) in there. I spaced it off when writing it. It makes things look nicer.

Answer 24

is this right @wrstlr3232

Answer 25

Looks good. you want f(3)=2.5...
Sorry, I should have explained that better.
You may need to solve them too. It all depends on your teacher/book.

Answer 26

thanks a lot!

Answer 27

No problem. I love functions!
