1) the vertex of a parable is given for two points, ( -b/2a, -b2-4ac/4a)
2) Now substitute the values in the equation
x = - (-8)/2(-2) = 8/ -4 = -2
y = -(8^2-4(-2)(1)/ 4(-2) = -(64-8) /-8 = 56/8 = 7
v(-2,7)
X=3
Explanation :-
20/5=4
8/2=4
They are both 4 so you will do
(5x-11)=4
-11+11=0
4+11=15
5x=15
15/5=3
x=3
Hope it helps
Answer:
1/3x=y-3, y=2/3x
Step-by-step explanation:
1/3x=y-3 is a linear function because there are no powers.
y=x^3+2 is not a linear function because x is squared by 3.
y=6x^2 is not a linear function because x is squared by 2.
y=2/3x is a linear function because there are no powers.
