We will have the following:

Now, we corroborate with one of the expression, in our case we will analyze y = x^2:

So, the expression taht represents the value given is:

Answer:

S': (2, 1)

T': (5, 3)

U': (1, -4)

S'': (1, 3)

T'': (4, 5)

U'': (0, -2)

Step-by-step explanation:

Hi!

For Reflection Across the X-Axis use this :

(x, y) -> (x, - y)

So :

S': (2, 1)

T': (5, 3)

U': (1, -4)

and then the question also asks for a translation so we follow what it gave us:

S'': (1, 3)

T'': (4, 5)

U'': (0, -2)

Please ask me any questions that you still may have!

and Have a great day! :)

Answer:

S' (2, 1)         S'' (1, 3)

T' (5, 3)        T'' (4, 5)

U' (1, -4)       U'' (0, -2)

Step-by-step explanation:

The preimage is S (2,-1), T (5, -3) U(1,4).

Preimage: the original figure prior to a transformation.

The directions say to reflect the preimage over the x-axis.

To do this, follow this transformation rule: (x, y) → (x, -y)

This means keep the x-coordinate as it is, but then change the sign of the y-coordinate.

S (2, -1) → S' (2, 1)

T (5, -3) → T' (5, 3)

U (1, 4) → U' (1, -4)

Next, take the coordinates from the last transformation then translate it using the rule: (x, y) → (x-1, y+2)

This means subtract 1 from the x-coordinate, then add 2 to the y-coordinate.

S' (2, 1) → S'' (1, 3)

T' (5, 3) → T'' (4, 5)

U' (1, -4) → U'' (0, -2)

Notice that each time you do a transformation, you add an apostrophe next to the letter. In math, this symbol is called a 'prime symbol.'

The equation for constant proportionality is y ∝ m .

1760 is a constant of proportionality.

The ratio of two proportional values at a constant value is the proportionality constant. When either the ratio or the product of two variables results in a constant, the connection between the two is proportional. The ratio between the two stated quantities affects the proportionality constant's value.

The formula y = 1760m describes the relationship between a distance in yards (y) and a similar value in miles (m).

As a result, the graph of the aforementioned equation will be a straight line with a constant slope of 1760 that passes through the origin (0, 0).

As a result, a measurement in yards and a measurement in miles have the same proportionality relationship.

Answer:

Step-by-step explanation:

A is 5 units above the x axis so a' will be 5 units below the x axis.

A place where two or more curves, lines, or edges converge is known as a vertex in geometry (plural: vertices or vertexes), and it is frequently identified by letters like,,,. As a result of this definition, vertices are the intersection of two lines that create an angle as well as the corners of polygons and polyhedra.

The solutions are:

P' = (-4,-7)

Q ' = (-8,-7) (-8,-7)

R ' = (-3,3) (-3,3)

All you have to do is flip the provided points P, Q, and R's x and y coordinates.

The common principle is (x,y) —-> (y,x)

Thus, when we reflect across the line y = x, something like P = (-7,-4) becomes P'= (-4,-7). The similar approach is taken with the other points.

By the concept of measurement of length we get the remaining length of the pipe 65 cm.

The total length of pipe before it was used by the plumber was 2.5 metre = (2.5 x 100)cm = 250cm.

Since,the plumber needs to cut lengths of 60cm, 35cm and 90cm

Thus,total Length of the pipe cut  by the plumber = 60cm + 35cm + 90cm = 185cm

After subtracting the length of pipe used by the plumber from the original length of the pipe, we get,

The remaining length of the pipe = 250 - 185 = 65cm

Hence, the remaining length of the pipe is 65 cm.

Hello!

First, let's write the coordinates of each vertex of this parallelogram:

• A (-4, 2)

• B (2, 2)

• C (5, -2)

• D (-1, -2)

As line AB is parallel to the x-axis, we can find its measurement without formulas. We just need to count the number of squares from one point to the other.

So,

We will follow the same reasoning to calculate CD (because it's also parallel to the x-axis).

Now we have to use the formula of the distance between two points to calculate the sides BC and DA. The formula is:

As we know the formula, let's replace it with the coordinates:

We can solve it using the same formula as I used to solve BC, but now I'll show you how to solve it using Pythagoras Theorem (I think it will be easier). Look:

Based on the linear relationship between the ticket numbers and the total cost, the cost of one ticket can be found to be A. $10.50

First, find the rate of change in ticket pricing assuming the number of tickets is x and the total cost is y.

The rate of change is:

= Change in y / Change in x

= (67.50 - 46.50) / (5 - 3)

= $10.50

Then find the y-intercept:

y = Slope(x) + y-intercept

67.50 = 10.50(5) + y-intercept

y-intercept  = 67.50 - 52.50

y-intercept = 15

Linear equation is:

Total cost = Rate of change (Tickets) + y-intercept

A single ticket would cost $10.50 which is the rate of change.

Question 4

Answer: Alternative C - 0

Step-by-step explanation:

Since x→∞, we can substitute the values of x for values as 10, 100, 1000 and see the tendency of the function when the values are getting higher (closer to ∞):

For x = 10

f(10) = 0.5*10^(-3/4)

f(10) = 0.089

For x = 100

f(10) = 0.5*100^(-3/4)

f(10) = 0.016

For x = 1000

f(10) = 0.5*1000^(-3/4)

f(10) = 0.003

As we can see, when the x-values are getting closer to infinite, the y-values tends to zero. Thus, alternative C is correct.

The measure of ∠E will be equal to 38°.

Given,

m∠BFE = 118° and m∠C = 86°

And BF bisects ∠ABD

From the Property of Linear Pair,

∠AFB + ∠BFE = 180°

=> ∠AFB + 118° = 180°

=> ∠AFB = 62°

Now, we can see that ∠AFB and ∠FBD are equal because they are alternate angles.

And ∠FBD and ∠ABF are equal because BF bisects ∠ABD.

So, In ∆ABF,

∠AFB + ∠ABF + ∠BAF = 180° (because of the angle sum property of a triangle)

=>62° + 62° + ∠BAF = 180°

=>∠BAF = 180° - 124°

=> ∠BAF = 56°

Similarly, in ∆ABE,

∠A +∠C  +∠E = 180°

=> 56° + 86° + ∠E = 180°

=> ∠E = 38°

Therefore, m∠E = 38°.

The coordinates of G is (d+c, b)

This is because the opposite sides of any parallelogram are equal in length, and so the length of side HG is equal to the length of side EF.

a) The length of side HG is equal to the horizontal distance (x2 - x1): xG - 0

The length of side EF is equal to the horizontal distance (x2 - x1): d - (-c) = d +c

Thus:

xG - 0 = d + c

xG = d + c

Therefore the x-coordinate of G is d + c

b) To find the y-coordinate of G, we also apply the idea that sides GF and HE are equal.

The length of side GF is equal to the vertical distance (y2 - y1): yG - 0

The length of side HE is equal to the vertical distance (y2 - y1): b - 0

Thus:

yG - 0 = b -0

yG = b

Therefore the y-coordinate of G is b

Finally, the coordinates of G is (xG, yG) = (d+c, b)

The three consecutive even integers such that one less than four times the third is equal to five more than the sum of the first two is -4,-2,0.

An integer is a whole number irrespective of the sign that the integer is all whole numbers that are going from 0 to infinite or 0 to minus infinite.

Integer ; ....-2 , -1 , 0 , 1 , 2 , .....

Integers are non-decimal numbers and all integers are rational numbers.

Let's assume that first, even integer is x

Then the second and third will be x + 2,x + 4 respectively.

As per the given,

1 less than 4 times the third → 4(x+4) - 1

It is equal to the 5 more than the sum of x and x + 2

So, x + x + 2 + 5

Therefore,  4(x+4) - 1 = x + x + 2 + 5

4x + 16 - 1 = 2x + 7

4x + 15 = 2x + 7

2x = 7 - 15

x = -4
