Answer:
D) 
Step-by-step explanation:
<u>Vertex Form of a Vertical Parabola:</u>

Vertex -> 
Axis of Symmetry -> 
Vertical Scale Factor -> 
- To turn
into vertex form, we need to complete the square on the right side - Therefore, if
, then
completes the square on the right side - This becomes

- This means that our function in vertex form is

Therefore, the vertex of the graph is
.
Ya, what is the question?
45.2 is the constant hope this helps! please give branliest
Answer:
P= 3/13
Step-by-step explanation:
R=7
B=7
Total=14
P(one red marble)=7/14=1/2
P(another red marble no replacement)=6/13
1/2 times 6/13=6/26=3/13
A straight line is 180°. So you can do:
(15x - 4) + (5x - 8) = 180 Simplify
20x - 12 = 180
20x = 192 Find the value of x
x = 9.6
m∠ABD = 15x - 4 Plug in x = 9.6
m∠ABD = 15(9.6) - 4 = 144 - 4 = 140°
m∠DBC = 5x - 8 Plug in 9.6
m∠DBC = 5(9.6) - 8 = 48 - 8 = 40°
