Answer:
f(x) = 1.2x
Step-by-step explanation:
Given:
f(x - 5) = 1.2x - 6
Required:
Find f(x)
To solve f(x), we have to express f(x - 5) in terms of f(x).
This is done as follows
f(x - 5) = 1.2x - 6
Factorize the expression at the right hand side
f(x - 5) = 1.2(x - 5)
Now we can solve for f(x) by substituting x for x - 5 in the above expression (on the right hand side and the left hand side)
f(x) = 1.2x
Hence, if f(x - 5) = 1.2x - 6 then f(x) = 1.2x
When you take the square root of a plus number, you get 2. It is often written as +/- something.
For example sqrt 64 = +8 and - 8
(8)*(8) = 64
(-8)(-8) = 64 Remember when 2 minus' are multiplied together, you get a plus.
Oddly, when you take the cube root of something, you get only 1 answer. When you take an advanced math course, you will find out that it is three. But until you know what a complex number is, the answer is 1.
15% of 420
That is 0.15 of 420
that is 0.15 * 420
that is 63
Hope this helps :)
