Answer:
Missing value is -4/3 and whole solution can be written as ( 8,-4/3)
Step-by-step explanation:
Given equation 2x+3y=12
solution ( 8,)
solution is form (x,y) hence in (8,) x is given as 8 while y is missing to find y
we will plug 8 as value of x in equation 2x+3y=12. From this equation we will find the missing value.
2x+3y=12
=> 2*8+3y=12
=> 16 + 3y = 12
=> 3y = 12-16= -4
=> y = -4/3
Thus, missing value is -4/3 and whole solution can be written as ( 8,-4/3)

Step-by-step explanation:
(a) Does the Parabola open upward or downward
Upward - the open "space" is above the vertex, so it opens upward
(b) X and y intercepts
x - intercepts : where the graph touches the x - axis
x - intercepts = (2, 0) , (4, 0)
Warning, don't get it mixed up! X - intercepts have y - values of 0, and y - intercepts have x - values of 0
y - intercepts : where the graph touches the y - axis
y - intercepts = (0, 3)
(c) Vertex of the parabola
vertex: the point of symmetry
vertex : (4, -1)
(d) Axis of symmetry
axis of symmetry : x - value of vertex
axis of symmetry : x = 4

I'm not to sure but i'm pretty sure the substitution method is the way to solve this
Answer:
175.84 m
Step-by-step explanation:
Given that:
A circular garden which has a radius of 28 m.
= 3.14
To find:
The fencing required to enclose the circular garden ?
Solution:
Here, we are given a circle and its radius.
We are required to find the perimeter of the circle in order to find the fencing required to enclose the circular garden..
Formula for finding the perimeter of a circle is:
Perimeter = 
where 
is the radius of the circle.
Using the given values in the formula:
Perimeter = 
= <em>175.84 m</em>
Therefore, 175.84 m of fencing is required.
