Answer:
A) 2/7y=200
B) There are more species of plants as the number of species of birds that have been sighted in Everglades National Park is 280
Step-by-step explanation:
Total number of species of birds that migrate = 200
We are given that of all the species of birds are sighted in the park
a)Write an equation to find the number of species of birds that have been sighted in Everglades National Park.
Let y be the number of species of birds that have been sighted in Everglades National Park.
We are given that of all the species of birds are sighted in the park
So, 2/7y=200
y=200x7/4
y=280
B)There are 600 species of plants in Everglades National Park. Are there more species of birds or plants in the park?
So, There are more species of plants as the number of species of birds that have been sighted in Everglades National Park is 280
The smallest natural number is 1 and the smallest whole number is 0 so
1x0=0
i hope that’s right
Answer:
The equation of the axis of symmetry is x = 
The coordinates of the vertex are ( , 
) ⇒ 2nd answer
Step-by-step explanation:
The quadratic function y = ax² + bx + c is represented graphically by a parabola which has a minimum/maximum vertex (h , k), where
- h =
and k is value y at x = h - The axis of symmetry of the parabola is a vertical line passes through the vertex point and its equation is x = h
- The minimum/maximum value of the function is (h , k)
∵ y = 4x² + 5x - 1
∵ The form of the quadratic function is y = ax² + bx + c
∴ a = 4 , b = 5 , c = -1
∵ The coordinates of the vertex points are (h , k)
∵ h =
∴ h = 
- To find k substitute x in the function by
∵ k = 4 ( )² + 5( ) - 1
∴ k = 4 ( 
) + ( 
) - 1
∴ k = 
- 
- 1
∴ k =
∴ The coordinates of the vertex are ( , )
∵ The equation of the axis of symmetry is x = h
∵ h =
∴ The equation of the axis of symmetry is x =
Answer:
i looked it up in math ay and i got nothing i put 6x + 15 in to it and it said ***Factor 3 out of 6x + 15** **3 2x + 15**
Step-by-step explanation:
hope this helps
