Answer:
Y+9>= -1
Step-by-step explanation:
The sum of a number y and 9 means that we wanna add Y and 9, but since y is a variable and 9 is just a number, we can't add them.
Now we have Y+9
Now, we plug in our inequality sign which is at least.
at least is >=
Now we have Y+9>=
And all you have to do is place the negative one after the inequality sign, and you get Y+9>= -1
Hope this helps! :)
Starting off, if you understand the quadratic formula (if you don’t look up the formula) you’re looking for A,B, and C. A is 3, B is -4, and C is 11. You would then plug in these numbers following the quadratic formula, which results in;
The first option is the correct one. :)
<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:
i
Step-by-step explanation:
you have nothing for us to solve so if you need the definition of it just let me know, but it is represented by the letter "i"
