Best ResponseYou've already chosen the best response.0i just need to know if i am to subtract 2.5 from 10.

Best ResponseYou've already chosen the best response.0i have to complete a table to solve the equation 2.5x  10.5 = 64(0.5^x)

Best ResponseYou've already chosen the best response.2y = f(x) slope = 2.5 and b = 10.5 y = mx + b

Best ResponseYou've already chosen the best response.2for example when x = 0 on the left f(x) = 10.5 and on the right 64(0.5^x) = 8 10.5 is not equal to 8 so x = 0 is not a solution

triciaal

Best ResponseYou've already chosen the best response.2** on the right = 64 10.5 not = 64 so x = 0 not a solution

Best ResponseYou've already chosen the best response.0they gave me that graph, i can't change the 2. i probably should change the 10 .

Best ResponseYou've already chosen the best response.2but do you see how I did x = 0 before I saw the table

triciaal

Best ResponseYou've already chosen the best response.2they want you to do from x = 2 to x = 6

Best ResponseYou've already chosen the best response.2since you have the graph maybe you just have to look at the graph and fill in the table

Best ResponseYou've already chosen the best response.0okay, but that's not what i'm asking. i'm asking if i am to subtract 2.5 from 10.5 to solve the f(x) equation.

Best ResponseYou've already chosen the best response.2you have to use the value of x then you can compute. you cannot subtract a number from a variable. you can only add or subtract when you have like terms

triciaal

Best ResponseYou've already chosen the best response.2a term with x is not like a number apples and oranges

triciaal

Best ResponseYou've already chosen the best response.2to directly answer your question no you cannot subtract 10.5 from 2.5 x because they are not like terms.

Best ResponseYou've already chosen the best response.0i understand. so do i subtract how do i find the first input on the table?

Best ResponseYou've already chosen the best response.0i didn't mean to send the "so do i subtract" part. sorry.

Best ResponseYou've already chosen the best response.2I did when x = 0 I did when x = 3 and I did when x = 6 follow along replace the x with 4 and compute fill in the table replace the x with 5 and compute then fill in the table

triciaal

Best ResponseYou've already chosen the best response.2again, the solution is the value of x that gives the same value in the table for f(x) and for g(x)

triciaal

Best ResponseYou've already chosen the best response.2you said you have the graph. the solution is the point where the lines cross/intersect

anonymous

Best ResponseYou've already chosen the best response.0oh, i didn't mean graph earlier, i meant table. the graph comes in later, to check the work.

anonymous

Best ResponseYou've already chosen the best response.0and i'm sorry, but i don't know if i'm following you. so the x in 2.5x  10.5 is either 2, 3, 4, 5, or 6? and i fill the x in the f(x) and g(x) equations with those numbers until they equal each other?

anonymous

Best ResponseYou've already chosen the best response.0for example: f(x) = 2.5(2)  10.5 = 5  10.5

Best ResponseYou've already chosen the best response.0f(x) = 2.5x  10.5 = 2.5(2)  10.5 = 5  10.5 = 5.5 correct so far?

anonymous

Best ResponseYou've already chosen the best response.0okay. then: g(x) = 64(0.5^x) = 64(0.5^2) = 64(.25) = 16 correct?

anonymous

Best ResponseYou've already chosen the best response.0and for f(x) 2 i would fill in 5.5, and for g(x) 2 i would fill in 16?
