Answers:
Vertex is (-1,0)
Axis of symmetry is x = -1
============================================
Explanation:
F(x) = 3(x+1)^2
is the same as
y = 3(x-(-1))^2 + 0
which is in the form
y = a(x-h)^2 + k
We can see that
a = 3
h = -1
k = 0
Therefore the vertex is (h,k) = (-1,0)
The axis of symmetry is x = h = -1 which is the equation x = -1
The axis of symmetry in this case is a vertical line through the vertex.
Answer:
6 to the power of 1 over 6
ANSWER
Yes, it is a quadratic equation which is x² + 3x - 70 = 0
SOLUTION
Area = Length × Width
Let x be the Length, L = x
Length is 3 cm longer than its width, thus, W = x + 3
The Area is equal to 70m², thus, A = 70m²
In Mathematical representation,
A = L × W
70 = (x)(x + 3)
70 = x(x) + x(3)
70 = x² + 3x
0 = x² + 3x - 70
Answer:
15(5)+3=78
21(5)+4=109
78+109=187

Answer:
b. $25
step-by-step explanation:
$375 / 15
25 coffee makers
$375 / 25
15 coffee makers
$375 / 40
9.375 coffee makers which makes no sense
$375 / 55
6.81818182 coffee makers which also makes no sense
coffee makers are usually over $20 so b makes the most sense here
