Given:
The graph of a quadratic function [tex]y=x^2-4x+3[/tex].
To find:
(a) The coordinates of the turning point.
(b) The roots of the equation [tex]y=x^2-4x+3[/tex]
Solution:
(a)
From the given graph it is clear that first the graph is decreasing after that it is increasing. So, the minimum point is the turning point.
The turning is at (2,-1) because the distance between the turning point from the y-axis is 2 and from the x-axis is 1 in the downward direction.
Therefore, the coordinates of the turning point are (2,-1).
(b)
The x-intercepts are the roots of an equation because roots are the x-coordinates of the points where the graph intersect the x-axis.
From the given graph it is clear the graph intersect the x-axis at x=1 and x=3.
Therefore, the roots of the given equation are 1 and 3.

A sign in front of a roller coaster says "You must be 40 inches tall to ride." What percentage of this height is: (use whatever strategy you would like)
Answers
The question is incomplete. The complete question is :
A sign in front of a roller coaster says ''you must be 40 inches tall to ride". What percentage of this height is A). 34 inches and B). 54 inches
Solution :
It is given that " You must be 40 inches tall to ride."
The formula used will be :
% [tex]$=\frac{V}{T} \times 100$[/tex]
Where, V is the value of the percentage to be calculated
T is the value out of which the percentage of V is to be calculated.
A). What percentage of 40 inches is 34 inches
Where, V is 34 inches and T is 40 inches.
Therefore, the percentage of 34 inches in 40 inches will be
[tex]$\frac{34}{40} \times 100$[/tex]
= 85 %
B). What percentage of 40 inches is 54 inches
Where, V is 54 inches and T is 40 inches.
Therefore, the percentage of 54 inches in 40 inches will be
[tex]$\frac{54}{40} \times 100$[/tex]
= 135 %
Graph the image of the figure using the transformation given.

Answers
The original image undergoes reflection across x=-3.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
In the given graph DEFG is the original image.
D'E'F'G' is the new image after the transformations applied.
A reflection is defined by the axis of symmetry or mirror line. In the above diagram, the mirror line is x = -3.
Under reflection, the shape and size of an image is exactly the same as the original figure.
This type of transformation is called isometric transformation.
Hence, the original image undergoes reflection across x=-3.

3.Anything in parentheses are considered factors.
4.If there is more than one term, then there is only one factor.
Answers
Answer:
2
Step-by-step explanation:
6 is not a factor only terms count as factors
The number 6 is the only number in the expression. Then the correct option is 2.
What is factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
Simply said, it is the biggest common element. The highest consistent element in the above example is 15, making 15 the greatest common factor amongst 15, 30, and 105. The biggest chunk of the common factors is called the "Greatest Common Factor" (of two or more numbers).
The expression is given below.
⇒ (b + 6)
The number 6 is a factor only terms count as factors because the variable b is the multiple of 6.
The number 6 is the only number in the expression. Then the correct option is 2.

Nathan is making chocolate chip cookies, the recipe calls for 2 cup chocolate chips and will make 4 dozen cookies. He increases the recipe to make 6 dozen cookies and will need 3 cups chocolate chips. Find the constant of proportionality
Answers
Answer:

Step-by-step explanation:
Nathan is making chocolate chip cookies, the recipe calls for 2 cup chocolate chips and will make 4 dozen cookies. He increases the recipe to make 6 dozen cookies and will need 3 cups chocolate chips. Find the constant of proportionality
From the above question, we can see that the Number of Chocolate chips is directly proportional to the number of Dozen cookies
Hence:
C = Chocolate chips
D = Dozen cookies
Hence:
C ∝ D
C = kD
Where k = Constant of Proportionality.
We are told that , the recipe calls for 2 cup chocolate chips and will make 4 dozen cookies.
Hence:
2 = 4k
k = 2/4
k = 1/2
Also, He increases the recipe to make 6 dozen cookies and will need 3 cups chocolate chips.
3 = 6k
k = 3/6
k = 1/2
Therefore, from the calculations above, the constant of proportionality is 1/2

First, you add 6+5, which equals 11. Then you have 11a = -11. Since all you have to do is multiply 11 by one and you get 11, add a negative symbol in front of it. 11 x -1 = -11

x = all real numbers
Step-by-step explanation:
3(3x+2)-2x=7x+6
Distributive property: 3(3x+2) = 9x + 6
9x + 6 - 2x = 7x + 6
Combine like terms: 9x - 2x = 7x
7x + 6 = 7x + 6
Since the two sides are completely the same, x = all real numbers (no matter what value you put in for x it will always be true)
