<u>Answer:
</u>
The vertex of the function 
is (h,k) = (3 , -1)
<u>Solution:
</u>
The vertex form of quadratic equation is generally given as,
Where h,k is the vertex of the parabola.
From question, given that 
.
we have to find the vertex of the function.
Let us first convert the given quadratic equation to vertex form (eqn 1)
By adding “9” on both sides of equation, we get
By using the identity 
,the right hand side of above equation becomes,
Now,the equation is of the vertex form.
By comparing with 
we get the values of (h,k)
a = 1; h = 3; k = -1
hence the vertex of the function is (h,k) = (3 , -1)

Answer:
x=1, y=-5
Step-by-step explanation:
Given equations are:
In order to solve the equation
Multiplying Eqn 1 by 5 and eqn 2 by 3 and subtracting them
So,
Eqn 1 becomes
15x+50y=-235
Eqn 2 becomes
15x-21y=120
Subtracting 2 from a
15x+50y - (15x-21y) = -235-120
15x+50y-15x + 21y = -355
71y = -355
y = -355/71
y =-5
Putting y= -5 in eqn 1
3x+10(-5) = -47
3x -50 = -47
3x = -47+50
3x = 3
x = 3/3
x = 1
Hence the solution is:
x=1, y=-5
Answer: 764
Step-by-step explanation:
Answer:
y=2.5x+6
Step-by-step explanation:
y= weight
6 is the weight that the baby is born so you would add it to the end making it the b
5 pounds every 2 months so 2.5 pounds every 1 month.
