Answer:
The first one is not liner
Step-by-step explanation:
This isn't linear because the y values increase inequally. It adds 2 and then 3 instead of keeping a constant rate
I think it would be like how many times does 5 go into 48.. and that would be 9 and 3/5
From the problem, the vertex = (0, 0) and the focus = (0, 3)
From the attached graphic, the equation can be expressed as:
(x -h)^2 = 4p (y -k)
where (h, k) are the (x, y) values of the vertex (0, 0)
The "p" value is the difference between the "y" value of the focus and the "y" value of the vertex.
p = 3 -0
p = 3
So, we form the equation
(x -0)^2 = 4 * 3 (y -0)
x^2 = 12y
To put this in proper quadratic equation form, we divide both sides by 12
y = x^2 / 12

Answer:
exact form: 13/5
Decimal form: 2.6
x= 2 3/5
Step-by-step explanation:
3x+4x-7=8-3x+11
7x-7=8-3+11
7x-19-3x
7x-7 + 7 =-3x+19+7
7x=-3+26
10x=26
x= 13/5
