I think of a number, multiply it by 6 and add 12. I get 4 more than 8 times my original number. a) Write an equation to represent the problem.

let the number be x.

now, according to above statement required equation is :

let's find the actual number

Hey there!

Let's take the number as 'x'.

So, if we multiply x by 6 we will get -> 6x. Then we should add 12 to it & we will then get the left-hand side (LHS) as -> 6x + 12.

Next for the right-hand side, we should multiply the number (x) by 8 times, -> 8x & add 4 more to it. We'll get the terms as -> 4 + 8x.

So, now the equation together becomes -> 6x + 12 = 4 + 8x.

Hope it helps ya!

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
