Answer:
When you multiply the first number of each polynomial by the second. Then you add the products together and combine like terms to simplify.
Step-by-step explanation:
I don't really know how to explain this, lol.
7/10, division is not possible so we right 0. ( zero point ) and multiply 7 by 10
(7*10)/10=70/10... 10 goes into 70, 7 times, so we write 0.7 (zero point seven)
1. 7/10 = 0.7, not repeating
4 20/30 = 2/3 = 0.666... repeating
13. 1/17/20 = 37/20 = 1.85
I am not sure but I say
2
3
2
9
Your vertex would be (-1,-5)
and your axis of symmetry is x=-1
Desmos it’s super easy just type it in and it will give explanation
