The vertex of the given quadratic function is (-3, 0).
What is vertex form of a quadratic equation?The vertex form of a quadratic equation or function is [tex]f(x)=a(x-h)^{2} +k[/tex].
Where,
(h, k ) is the vertex
And, a is constant.
According to the given question
We have a quadratic function
[tex]f(x) = x^{2} + 6x + 9[/tex]
The above function can be written as
[tex]f(x) = x^{2} +2(3x) +9[/tex]
⇒[tex]f(x) = x^{2} + 2(3x) + (3^{2}) -(3)^{2} + 9[/tex]
⇒[tex]f(x) = (x+3)^{2} -9+9[/tex]
⇒[tex]f(x) = (x+3)^{2} + 0[/tex]
Comparing the above equation with the standard vertex form of quadratic function we get
h = -3 and k = 0
Hence, the vertex of the given quadratic function is (-3, 0).
Thus, option A is correct.

Choose the equation for the line in slope-intercept form.

A. y=2x+3
B. y=12x+3
C. y=12x−3
D. y=−12x−3
Answers
To do this use the formula change in y/ change in x
So If we pick two points, say 0,-3 and -4,-5 the change in y is from -3 to -5 so it is -2 and the change in x is from 0 to -4 so is taking away 4 so the gradient is -2/-4 which is 1/2.
Then we need to work out the y intercept, c.
Substitute the gradient into y= Mx+ c to get y = 1/2 x + c. Use a point to substitute in and solve:
Eg 4, -1 —> -1 = 1/2 x 4 + c
Then -1 = 2 + c
Then -3 = c
So you get the end equation of
Y = 1/2x -3

Step-by-step explanation:
first you have to find the value of X. So you take both expressions and make them equal to 180 degrees. Then you solve for X. Once you do that X should equal 30. Then in place of X plug in 30 and solve. it should look like this (3(30)+22). The answer is 112 degrees.
You could of also looked at your angle and saw it was an obtuse angle. The only answer that was obtuse was 112 degrees.

how do you combine like terms
Answers
Answer: you add them up
Step-by-step explanation:
Explanation:
Combining like terms is commonly used to solve algebraic expressions. Like terms are those species or variables that are the same in any algebraic representation.
Different mathematical operations can be performed on like species. We can add, divide, multiply, subtract, factorize, etc those terms.
Take for example;
Solve;
5x + 3 = 4x + 6
To solve this simply collect the like terms;
5x and 4x, 3 and 6 are like terms
5x - 4x = 6 - 3
x = 3
This is one way of solving problems by collecting like terms.
