Answer:
4x + 11 is the answer when you combine like terms
Answer:
p = q/5 - 9r/5
Step-by-step explanation:
Step 1: Write equation
5p + 9r = q
Step 2: Solve for <em>p</em>
<u>Subtract 9r on both sides:</u> 5p = q - 9r
<u>Divide both sides by 5:</u> p = q/5 - 9r/5
Since
the domain of f(x) is the set of non-negative integers, because we can't feed a square root with negative inputs. So, you couldn't comput f(-9)
Unless you're allowed to use complex numbers, in that case we have
Which evaluates to
Simplifying is basically 1 + 1, so the answer is 2, or 8/4 whichever you prefer.
It can also be 4/2, or 2/1...
-- Find any point where y=4
-- Find another point where y=4
-- With your ruler, draw a line between the two points.
You have a horizontal line, and every point on it has y=4 no matter what 'x' is.
The equation for every straight line is [ y = mx+b ].
This is the line where (m = 0) and (b = 4).
