Answer:
1.
a = 1 b = 3 c = 11
2.
a = 1 b = -7 c = -11
3.
a = 1 b = 4 c = -9
4.
a = 3 b = -1 c = 16
5.
a = 1 b = 0 c = -9
6.
a = 2 b = 5 c = 0
7.
a = -4 b = 0 c = -3
8.
a = 6 b = 0 c = 0
9.
a = -1 b = 1 c = 0
Hope this helps took me a long time to type
Answer:
12.2
Step-by-step explanation:
C is your answer. The coefficient on the x value is always a stretch factor.
In order to make a fraction a ratio, you must simplify it if it is needed. So for 12/9, you can divide 3 from the numerator and denominator. That would equal 4/3. Now that it is simplified, you can make it into a ratio. (can be using ":" or using the word "to")
One way it can be used is --> 4:3
Another way --> 4 to 3
Good luck!
