Answer:
(1,3)
Step-by-step explanation:
The given function is
Factor 2 from the first two terms
Add and subtract the square of half the coefficient of x.
Let us create perfect square trinomial
This implies that:
Therefore the vertex is (1,3).
We got this by comparing to
1. The relationship is proportional.
2. The slope is negative.
3. The equation is y = -3x
X + 40 + 19 + 37 = 180. top middle
x + 96 = 180
x = 84
x + 90 + 90 + 63= 360 bottom
x + 243= 360
x = 117
right end above the bottom
x + 117 + 21 = 180
x + 138 = 180
x = 42
Where the 77 is vertical
x + 77 = 180
x = 103
x + 103 + 27= 180 next to the 77 vertical
x + 130 = 180
x = 50
those are the corrections
Answer:
Price of roses is proportional to the number of roses.
Step-by-step explanation:
Let the price of roses are proportional to the number of roses.
Equation representing this phenomenon will be,
P = k(R) ⇒ k =
where 'P' = price of the roses
R = Number of roses
k = Proportionality constant
If we substitute the values of P and R and we get the same value of constant 'k', then the equation will be true.
For R = 3 and P = $9
k =
k = 3
For R = 6 and R = 18
k =
k = 3
K is same in both the conditions, therefore, Price of roses are proportional to the number of roses.
