How many groups were there
Answer:
A
Step-by-step explanation:
8.5 x 8.5= 72.25
so basically it's the closest answer
Answer:
m = - 1.25
Step-by-step explanation:
20 = - 2(4m - 5) ← divide both sides by - 2
- 10 = 4m - 5 ( add 5 to both sides )
- 5 = 4m ( divide both sides by 4 )
-
= m , that is
m = - 1.25
The answer would be b because 3+7 is 10 and multiple that by 7 is 70. and 20 plus 49 is 70
-X²-4+7
=-X²+3
a=-1 b=0
X=-b/2a
X=0
If X=0, Y=3
So the Vertex is (0, 3).
That's your answer.
