Answer:
y = -2(x - 4)^2 + 4.
Step-by-step explanation:
Vertex form:
y = a(x - 4)^2 + 4 (because the vertex is at (4, 4)).
To find the value of a we substitute the point (2, -4):
-4 = a(2-4)^2 + 4
4a = -8
a = -2.
Answer:
Option d. 1 in: 12 ft.
Step-by-step explanation:
A scale model of building is 2 inches tall. If the building is 24 feet tall then we have to find the scale of the model.
Since scale of the model is represented by the ratio of size of scale model and size of original building

= 
= 
Therefore, Scale of the model is 1 inch : 12 ft.
You can factor a 12 out from both. 12 goes into 12m 12 times and 12 goes into 60 5 times. So you would pull it out front:
12(m+5)
That's as far as you can take it. Do you have to set it equal to 0, or some other number??
