Answer:
Okay you have isolate a variable. As long as you perform the some operation on both sides the equations holds true. So I'll multiply the bottom one by three. 3x - 3y = 27. Now if I add the equations together I get 5x is 35 or x is 7. Then plug it back into either equation. 7 minus what is 9? -2. Y is -2
We are considering the function

the graph of this function is the graph of the parent function

after applying the following steps.
1. multiply by -1:

is

reflected with respect to the x-axis.
2. multiply by 5:

is

shrinked towards the y axis.
for example, consider x=1/2

now this means that

is "lower" than

, which means there is a shrinking of the graph.
3. add 5:

is

shifted 5 units up.
4.
so the graph of the function a) opens down, b) is shifted 5 units up, c) is not wider than the parent function
Answer: False
Answer:
8.) Rational
10.) Irrational
Step-by-step explanation:
8.) This is rational because although it is a decimal, it is terminating, meaning it has an end.
10.) This is irrational because it is a repeating decimal with seemingly no pattern.
