The answer is the third option 78 degrees
2(5x+8)=6x+20
10x+16=6x+20
4x+16=20
4x=4
x=1
Answer:
20%
Step-by-step explanation:
- Set up a proportion:
- Cross multiply, then divide: 280 × 100 = 28000, 28000 ÷ 1400 = 20
- So, 20% were satisfied with their car

Answer:
Option A. 
Step-by-step explanation:
<u><em>The complete question is</em></u>
The function g is given in three equivalent forms.
Which form most quickly reveals the vertex?
A)g(x)= 1/2(x-8)^2-8
B)g(x)= 1/2(x-12)(x-4)
C)g(x)= 1/2x^2-8x+24
we know that
The equation of a quadratic function in vertex form is equal to

where
a is the leading coefficient
(h,k) is the vertex of the function
In this problem, the option A is the equation of the function in vertex form
we have

where the vertex is the point (8,-8)
therefore
Option A
