Answer:
CD with the line bar over it ↔
DC with the line bar over it ↔
Step-by-step explanation:
There are two possible names for the line
CD with the line bar over it ↔
DC with the line bar over it ↔
We need the line bar over it to indicate it is a line and not a line segment. A line goes on infinitely in both directions while a line segment stops
Answer:
A and B
Step-by-step explanation:
The minimum occurs at the turning point ( vertex )
The coordinates of the vertex are (1, - 2 ) → A
The x- intercepts are the points where the graph crosses the x- axis
This occurs at (3, 0 ) and (- 1, 0 ) → B
The axis of symmetry is a vertical line passing through the vertex
Equation of axis of symmetry is x = 1 , not y = - 2
(1, - 2 ) is a minimum not a maximum , see above
Answer:that hard
Step-by-step explanation:
4c+c+5c = 5c+5c= 10c
I added the single c to the 4c first to get another 5c then added the two 5c together to get 10c, since all terms have a single c in them all can be combined
Answer:
k = 15
Step-by-step explanation:
12/4/5 = 4/5/4/5 k
15 = k
OR
5/4 (12) = 4/5 (5/4) k (multiply by the reciprocal)
15 = k
