The required functions after transformations are y = -4(x+4)+5, y = (x-o)/14, y = -x+4

A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.

Given that, the equation for the parent linear value function, f(x)=x, that has been transformed by,

a) Reflecting across the -axis, vertical stretch by a scale factor 4, and a translation of 4 units up and 5 units left :-

Rule for reflection across x-axis = y = f(x) → y = -f(x)

After reflection,

f(x) = -x

And there is a vertical stretch by a scale factor 4, and a translation of 4 units up and 5 units left

f(x) = -4(x+4)+5

Therefore, the function will be f(x) = -4(x+4)+5

b) Vertical shrink by a scale factor of 14 and a horizontal shift O units right.

For vertical shrink = f(x)/14 = x/14

For horizontal shift = (x-o)/14

Therefore, the function will be f(x) = (x-o)/14

c) Reflection in the x-axis, a vertical shift of 4 units up and a horizontal shift 7 units left.

Rule for reflection across x-axis = y = f(x) → y = -f(x)

f(x) = -x

For a vertical shift of 4 units up and a horizontal shift 7 units left =

f(x) = (-x-7)+4

Hence, The required functions after transformations are y = -4(x+4)+5, y = (x-o)/14, y = -x+4

Answer:

Step-by-step explanation:

60 is the lowest common multiple of 12 and 15, not the greatest common factor.

The greatest common factor of 12 and 15 is 3, not 60.

The linear equation representing the data in the table is y = x - 3, therefore;

The slope, m = 1
The y-intercept, c = -3

A linear equation is an equation of the form y = m·x + c, in which the highest index of the variables is 1, and the graph of the ordered pairs obtained using the equation is a straight line.

The first difference of the y-variable is constant and each next value the x-variable increases by 1, therefore, the relationship is a linear relationship.

The slope, m, is therefore;

m = (-3 - (-4))/(0 - (-1)) = 1

The equation of the line that represents the graph of the data in the table using the point (3, 0) is therefore;

y - (0) = 1·(x - 3) = x - 3

Therefore; y = x - 3

The above equation is in the slope-intercept form, y = m·x + c, with the slope, m = 1, and the y-intercept, c = -3

The examples of SSS similarity theorem (i.e If all the three sides of a triangle are in proportion to the three sides of another one) are ∆ABC is similar ∆DEF and one large triangle is similar to smaller one as seen in above figure.

SSS Triangle Similarity Examples : 1) How can you use the SSS similarity criterion to show that the following triangles are similar?

Only non-zero angles are specified. SSA is not a measure of triangle similarity, so we cannot say that these triangles are similar by SSA. However, since they are right triangles, you can use the Pythagorean theorem to find the third side of any triangle.

=> x² = 45² - 36² = 2025 - 1296 = 729

=> x = √729 = 27

=> x² = 15² - 12² = 225 - 144 = 81

=> x =√81 = 9

All three pairs of sides are proportional in ratio 3. Therefore, triangles are more similar to SSS~.

2) Are the triangles (that is, ΔABC and ΔDEF) similar?

All triangles have the same three sides. The ratio between each pair of sides is 4x/x = 4. The triangles through SSS~ are similar because the three pairs of sides are proportional.

Th equation is linear at  -2 < x < 0 and 2 < x < 4.

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. Because of this, it is referred to as a "linear equation."

Given graph,

Answer:

X = -6, y = 8.

Step-by-step explanation:

Rearrange the second equation to the form ax + by = c

x + 2y = 10

2x - y = -20

Multiply equation 1 by -2

-2x - 4y = -20

Adding this to the second equation

-5y = -40

Y = 8.

Now substitute x = 8 into equation 1

X + 2(8) = 10

X = -6.

The length of the walkway in feet is 15.

Any plane shape that has four equal length of sides is referred to as a square. Its area is the amount of space that it covers in a 2 dimensional plane. And the area of a square is given as;

area of a square = length x length

                           = length^2

It is measured in squared units.

Given that there are 5 square carpet tiles which covered an area of 45 square feet, then the area of one square carpet tile is;

area of one square carpet tile = total area covered/ number of tiles

                                     = 45/ 5

area of one square carpet tile = 9 square feet

But,

area of a square = length^2

9 = length^2

length = 3 feet

What is a triangle?

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

Given that the base of the triangle is 12 cm and the hypotenuse is 32 cm.

The height of the triangle is 8 more than the base.

The height of the triangle is (12 + 8) = 20 cm.

The p-value for a lower tail test with a test statistic z of zero is 1, meaning that the probability of obtaining a result at least as extreme is 100%.

The lower tail test is a type of hypothesis test used to determine if a sample of data comes from a population with a certain mean or below. The test statistic z is used to calculate the p-value of the test, which is the probability of obtaining a result at least as extreme as the one observed. In this case, the test statistic z is zero, so the p-value of the test is 1, meaning that the probability of obtaining a result at least as extreme is 100%. To calculate this, the z-score is determined by subtracting the mean of the population from the sample mean and dividing by the standard deviation of the population. Then, the cumulative probability is calculated by finding the area under the normal distriabution curve from negative infinity to the z-score obtained from the calculation. The p-value is then equal to the cumulative probability. In this case, the p-value is 1 since the z-score is zero.

The values of the constants in the polynomial are a = 1, b = 0, c = 1 and d = -2

A polynomial is a mathematical expression involving a sum of powers in one or more variables, with coefficients that are real numbers.

The variables in a polynomial are typically represented by letters such as x and y, and the powers of the variables are represented by whole numbers.

We have polynomial (x – 2)(x² + 1) – x(x – 3), in order to write it in the form ax³ + bx² + cx + d,  we need to expand the expression. That is:

(x – 2)(x² + 1) – x(x – 3) =  (x² – 2)(x + 1) – x(x – 3)

                                      = x²(x + 1)  – 2(x + 1) – x(x – 3)

                                      = x³ + x² – 2x -2  – x² + 3x

                                      = x³ + x - 2

The order of the steps for the bisection of line segment AB will be D, E, B, C, and A.

The first thing we do for bisecting any line segment is to take up a distance of more than the approximate half of the line segment and place the compass on either point of the line.

Hence the first point will be D. Place the compass on point A and open it wider than half the distance of the segment.

Since an arc on both sides of the segment has to be drawn, the next point will be E. Swing an arc above and below the segment.

Since the same thing has to be repeated for the other point, the next point will be B. Keeping the compass the same width, place the compass on point B, and swing an arc above and below the segment.

Now we have got 2 points above and below the line segment, the next point has to be C. Place points C and D on the intersection of the arcs created above and below segment AB.

The line intersecting these points and AB has to be the point that divides AB in half, and the last point will be A. Draw a line from point C to point D.

The value of x if the point B is between the points A and C is (a) 25

From the question, we have the following parameters that can be used in our computation:

B is between A and C.

Also from the question, we have the following parameters:

AB = 50

BC = 3x

AC = 6x−25

The statement "B is between A and C" implies that

AC = AB + BC

Substitute the known values in the above equation, so, we have the following representation

50 + 3x = 6x - 25
