Answer 1

Do you have a math question? :P

Answer 2

Given: f(x)=4⋅2xf(x)=4⋅2x and g(x)=2x+6


What is the solution to the equation f(x)=g(x) ?

Note: Use the graphing method to solve.

Answer 3

@Vocaloid Yep, don't know this x/x

Answer 4

you just have to graph both equations and find the intersection

Answer 5

assuming that x is an exponent it should be this

Answer 6

it is. and its D

Answer 7

what's the answer choice say for D? you didn't provide the choices ^^'

Answer 8

oh, sorry, it was something like (1,8)

Answer 9

an = -2 * 3^(n-1)

when n = 1 (aka the first term) an = -2, making a1 = -2

the 3 part of the an implies that each term is multiplied by 3 to get the next term

making the rule an = 3*a(n-1) (answer B)

Answer 10

Alicia buys a new car for $20,000. The value of the car decreases by 15% each year.

In about how many years will the value of the car be $10,440?

Answer 11

the general equation for this is

value = initial amount(1-rate of decrease as a decimal)^number of years

plug in the values from the problem into the equation and then solve for # of years

Answer 12

C?

Answer 13

what does the answer choice C say

Answer 14

6

Answer 15

taking our equation from before we have:

value = initial amount(1-rate of decrease as a decimal)^number of years

10440 = 20000(1-0.15)^x

solve for x (you can use a calculator for this) wolframalpha.com

Answer 16

i now got D

Answer 17

what does D say

Answer 18

7

Answer 19

plug this into a calculator 10440 = 20000(1-0.15)^x and find the value of x

Answer 20

4?

Answer 21

i did that and got 4

Answer 22

good.

Answer 23

so 4 is the answer
