Solve the y system of inequalities by choosing the correct graph.y> 3y< |x-2|
Answers
The solution graph of the system of inequalities : y> 3 and y< |x-2| is attached below.
The given inequalities are:
y>3 and y< |x-2|
Now we will solve y< |x-2|
applying absolute value we get
x - 2 < -y or x - 2 > y
Now we will solve the two equations graphically.
Using the graph we can clearly see that the red part represents the inequality y< | x - 2 | while the blue part denotes the inequality y > 3
Hence the solution of the two inequalities will be the region shaded by both the graphs.
Any monotonically increasing function can, by definition , be applied both for sides of just an inequality without distorting their relationship as long as both expressions fall inside the scope of the function. If a monotonically falling function are applied to both sides of an inequality, the inequality relation might be reversed.

Answers
We have to find the transformations that led from polygon ABCD to WXYZ.
As the shapes are not equally oriented, we have to find if one of the transformation is a rotation or a reflection.
We can fin this by looking at the position of corresponding sides. So first, we have to find corresponding sides of the two polygons. The polygon WXYZ has also a scale transformation, so its size is proportional, with a proportion greater than 1 as it is bigger, to the size of ABCD.
Each side in the pre-image has a corresponding side in the image. Each corresponding side in the image will be k times bigger than the side in the pre-image, and this k is the same for the four sides.
We can look at the sides that are parallel to the axis, BC and CD, and see that CD is longer than BC. If we look at WXYZ, YZ is longer than YX.
Then, we can conclude that YZ and CD are corresponding sides as BC and YX.
The scale factor is k = 2 as YZ is twice as long as CD.
Then we can see, by the position of BC and CD respect to YX and YZ that no rotation can convert the pre-image into the image, so the orientation of the image is due to a reflection with axis of symmetry at x = 7.
Then, after the reflection, the image is dilated with a factor k = 2.
Answer:
B. A reflection of polygon ABCD followed by a dilation of the image with a scale factor of 2.

To do this, we simply substitute the x values at each point, to get the corresponding y-value
We proceed as follows:
A) At this point , x is-3 , so we substitute -3 for x
Mathematically:

Answers
ANSWERS
• g(x) = f(x) - 2
,• h(x) = -f(x)
,• m(x) = f(x) + 7
EXPLANATION
The values on the table of function g(x) are all 2 less than the values of f(x). Therefore g(x) = f(x) - 2.
The values of function h(x) are all the opposite of the values of f(x). Therefore h(x) = -f(x).
The values of function m(x) are all 7 more than the values of f(x). Therefore m(x) = f(x) + 7.

What is conversion?A conversion factor is a quantity that is multiplied or divided between two different sets of units. In the event that a conversion is necessary, it must be carried out using the proper conversion factor to produce an equivalent value. When translating between inches and feet, 12 inches equals one foot.
To represent the same attribute in a different unit of measurement, employ a unit conversion. Hours can be replaced with minutes, and miles can be replaced with feet, kilometers, or any other unit of measurement when describing distance. Measurements are frequently given in one unit of measurement, like feet, but are required in another, like chains.
Given,
The length of ribbon needed for the craft project = 182 inches
So, the length of the ribbon needs to be in meters.
Thus, we can convert inched to centimeters by
1 inches = 2.54 centimeters
As 1 cm = 0.01 m
So, 1 inch = 2.54 x 0.01 m
1 inch = 0.0254 m
Then for the length of 182 inches,
114 inch = 0.0254 x 182 meters
= 4.6228
≈ 5 meters
Therefore, the length of the ribbon is 5 meters

The slope-intercept form is:

For two lines to be parallel they have to have the same slope. So a line parallel to

[tex]y=-4x+b[/tex]To find the intercept b we use the given point (5,-7). We just have to replace these values of x and y into the equation above and solve for b:
[tex]\begin{gathered} -7=-4\cdot5+b \\ -7+20=b \\ 13=b \end{gathered}[/tex]So there we have the complete equation of the asked line:
