Step-by-step explanation:
we have
we know that
The solution of the function is equivalent to solve the following system of equations
------> equation A
------> equation B
The x-coordinate of the intersection point both graphs is the solution of the given function
Using a graphing tool
see the attached figure
The intersection points are and
therefore
The solution of the given function are
Solve x2 + 2 = 6 by graphing the related function. x^2 + 2 is a parabola with a vertex at the point (0, 2). When x = -1 or x = 1, then x^2 + 2 = 3, so we should put the points (-1,3) and (1,3) on the graph. When x = -2 or x = 2, then x^2 + 2 = 6, so we should put the points (-2,6) and (2,6) on the graph. We could continue adding points to the graph if we want, but we already have our two solutions. x^2 + 2 = 6 when x = -2 or x = 2. Therefore, x = -2, and x = 2 are the two solutions to this equation.
Answer: option C.
Step-by-step explanation:
Given a quadratic function of the form , if the coefficient a is less than zero, then the function is opened upward.
The options A is not opened upwards, then it is not the answer.
Then the given equation can be written as:
This function is equal to the parent function, shifted 4 units down.
Therefore, the graph that you are looking for must be a parabola that is opened upwards and has its vertex in the point (0,-4).
Then, the correct option is C. And the solution is:

Answer:
geometric
common ratio 2/3
Step-by-step explanation:
We know that the sequence is not arithmetic
3-2 =1
2-4/3 = 6/3 -4/3 = 2/3
The common difference is not the same
Now check geometric
The common ratio:
Take the second term over the first term
2/3
Now take the third term over the second term
4/3 ÷ 2
4/3 * 1/2 = 2/3
The common ratio is the same so the sequence is geometric with a common ratio of 2/3
A geometric sequence starts with 12,.
...,27,..., 60.75,...
where 12 is the first term, 27 is the third term and 60.75 the fifth term.
Work out the common ratio of the sequence.

Reflect shape A in the line x = -2
Answer: Check out the diagram below
The reflected image is shown in red.
=================================================
Explanation:
Draw a vertical line through -2 on the x axis. This is the mirror line.
Now focus on the upper right corner of the figure, which is at (-3, -1). Notice how the horizontal distance from this corner point to the mirror line is exactly 1 unit. If we move another 1 unit to the right, then we'll arrive at (-1,-1) which is where the reflected point lands or ends up.
In short, the upper right corner point (-3,-1) reflects over x = -2 to land on (-1,-1)
----------------------
As another example, the upper left corner point (-5, -1) will move exactly 4 spaces to the right to get to the mirror line. Then we move another 4 spaces to the right to get to (2,-1).
So the upper left corner (-5,-1) will ultimately move to (2,-1) after the reflection over x = -2.
Apply these steps to the other corner points and you'll end up with what is shown below.
Take note that a point like A(-5,-1) moves to A'(1,-1), and similar to the other points as well. Also, notice that when going from A to B to C, etc we are moving clockwise. We move counterclockwise when going from A' to B' to C' etc. Reflections always swap the orientation.
Transformation involves changing the position of a shape.
The coordinates of the image are:
[tex]\mathbf{A '= (1,1)}[/tex] [tex]\mathbf{B' = (-1,-1)}[/tex] [tex]\mathbf{C' = (-1,-4)}[/tex] [tex]\mathbf{D' = (0,-4)}[/tex]
[tex]\mathbf{E' = (0,-3)}[/tex] [tex]\mathbf{F = (1,-3)}[/tex]
The vertices of the shape are:
[tex]\mathbf{A = (-5,-1)}[/tex]
[tex]\mathbf{B = (-3,-1)}[/tex]
[tex]\mathbf{C = (-3,-4)}[/tex]
[tex]\mathbf{D = (-4,-4)}[/tex]
[tex]\mathbf{E = (-4,-3)}[/tex]
[tex]\mathbf{F = (-5,-3)}[/tex]
The rule of reflection across line x =-2 is:
[tex]\mathbf{(x,y)=(-x -4,y)}[/tex]
So, we have:
[tex]\mathbf{A '= (5 - 4,-1) = (1,-1)}[/tex]
[tex]\mathbf{B' = (3-4,-1) = (-1,-1)}[/tex]
[tex]\mathbf{C' = (3-4,-4) = (-1,-4)}[/tex]
[tex]\mathbf{D' = (4-4,-4) = (0,-4)}[/tex]
[tex]\mathbf{E' = (4-4,-3) = (0,-3)}[/tex]
[tex]\mathbf{F = (5-4,-3) = (1,-3)}[/tex]
So, the coordinates of the image are:
[tex]\mathbf{A '= (1,-1)}[/tex]
[tex]\mathbf{B' = (-1,-1)}[/tex]
[tex]\mathbf{C' = (-1,-4)}[/tex]
[tex]\mathbf{D' = (0,-4)}[/tex]
[tex]\mathbf{E' = (0,-3)}[/tex]
[tex]\mathbf{F = (1,-3)}[/tex]

A) 80/140 is the portion that describes the book readers over all people surveyed

Students at a local high school travel to school by car, bus, and bicycle. 1/5 of the 825 students Tavel by car, 48% of the students travel by bus, 0.08 of the students travel by bicycle. The remaining students travel to school by walking. How many students walk to the local high school?
Answer:
198 students walk to the local high school
Step-by-step explanation:
Total number students = 825
1/5 of the students travel by car
48% of the students travel by bus
0.08 of the students travel by bicycle
To find the number of students who wal to school we have to find the exact number of students who travel to school by car, bus and bicycle and subtract the result from the total number of students
Students who travel by car = 1/5×825
= 165 students
Students who travel by bus = 48% × 825
= 48/100 × 825
= 12/25 × 825
= 396 students
Students who travel by bicycle = 0.08 × 825
= 66
So now we add the results fo the equations above and subtract it from the total number of students to get the number of students that walk to school
Students that walk to school = 825 - (165 + 396 + 66)
= 825 - 627
= 198 students
Therefore 198 students walk to the local high-school
