Answer:
x = 3
Step-by-step explanation:
Hi there,
We know that the value of ∠ABD and ∠DBC are the same because BD bisects it. Therefore, we can set both of the angle values equal to each other to find the value of x.
9x = (8x + 3)
x = 3
Hope this answer helps. Feel free to ask questions. Cheers.

Answer:
See graph in attachment.
Step-by-step explanation:
The graph of 
is a parabola that has its vertex at the origin.
The equation of the transformed graph is
The vertex of this transformed function is
Drag the blue graph up so that the vertex will now be at (4,3).

Step-by-step explanation:
EF = 4x - 15
FG = 3x - 7
EG = EF + FG = 20
so,
4x - 15 + 3x - 7 = 20
7x - 22 = 20
7x = 42
x = 6
EF = 4×6 - 15 = 9
FG = 3×6 - 7 = 11
Answer:
Step-by-step explanation:
This is more easily understood if you take out a common factor of -1
-1(x^2 + 15x + 56)
7*8 = 56
7 + 8 = 56
-1 (x +8)(x+7)
