Answer:
[-1, 9], [-2, 10], [-3, 11], [1, 7]
Step-by-step explanation:
Starting from the y-intercept of [0, 8], I did <em>rise</em><em>\</em><em>run</em><em> </em>by moving one block <em>north</em><em> </em>over <em>one</em> block <em>west</em><em> </em>for the first three coordinates, but retracing back to the y-intercept, I moved one block <em>south</em><em> </em>over <em>one</em> block <em>east</em> for the last coordinate. It does not matter where you go, as long as you follow the pattern within this <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>].

Answer:

Explanation:
Determining the <em>domain</em> of the function P(x) = 2x + 8 is very trivial and does not require the uses of separate intervals.
The domain of a function is the set of input values (x) for which the function is defined. Thus, the domain of P(x) = 2x + 8 is all the real number, which in interval notaion is:
The symbol ∞ is used to indicate that there is not limit for the value of x: it can goe from any negative number to any positive number).
For didactic purposes let's determine the domain of the function
P(x) = 2/(x+8).
In this case, the function is not defined when the denominator equals 0.
Then, the domain excludes the values for which x + 8 = 0.
Then, the solution is all the real numbers different to - 8.
In <em>interval notation</em> it is:
In form of <em>inequaliy</em> that is:
That means, all the real numbers less than - 8 and all the real numbers greater than 8.
Substitution means making one formula equal to a variable in the second formula to plug it in, and elimination means the cancelling out of one variable in order to make it easy to solve.
1. x-4(-x+5)=10
x+4x-20=10
5x=30
x=6, plug in 6 into original equation, y=-1
2. <u>-1(2x</u>-5y=6)
<u>2x</u>+3y=-2 underlined means cancelled, so you add the rest up on each side
5y+3y=-6+-2
8y=-8
y=-1, plug in this value to original equation, x=.5
3. 2(x+5)=2x+10
2x+10=2x+10
Infinite solutions
4. y=<u>4x</u>-3
-<u>4</u>(y=<u>x</u>+6) underlined means cancelled
-3y=-27
y=9, plug into original, x=3
You need to cut the shape into other shapes that you know the formula off
