Remark
If you just want the way this would be written out the answer is
Note
1. The quotient is the answer of a division problem.
2. The number is represented by the letter x
Here is the equation:
You need to find f(3). To do that, substitute all the x's with 3:
The first thing you need to do is multiply 4 by 3. Multiply:
Here is your new equation:
To get your answer, you need to add 12 and 1. Add:
That means:

Answer:
(x) = x - 3
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x + 3 (subtract 3 from both sides )
y - 3 = x
Change y back into terms of x with x = (x) , thus
(x) = x - 3
Answer:
(6,2)
Step-by-step explanation:
y=-1/2x+5
y=2x-10
-1/2 x+5 =2x-10 to find the solution y=y ( point of intersection of two lines)
-1/2 x-2x = -10-5 solve for x
-5/2 x=-15
x=-30/-5=6
y=2x- 10 substitute x in the equation to get y
y=2(6)-10
y=2
The value in this case would be going up. Since .75 being multiplied by an increasing number would only increase, the value must be doing the same.
However, if that t were an exponent, the value would be decreasing. The more a number between 0 and 1 is multiplied by itself, the smaller it gets.
