The triangle UVW have vertices at U(-3, -4), V(-3, -3) and W(-2, -4). UVW is reflected across x = -2 to get U'(-1, -4), V'(-1, -3) and W'(-2, -4)

What is transformation?

Transformation is the movement of a point from its initial location to a new location. Types of transformations are rotation, translation, reflection and dilation.

Translation is the movement of a point either up, down, left or right in the coordinate plane.

f(x)= 2x-7/3x-4
Vertical and horizontal asymptotes.

Answers

We need to know about asymptotes to answer this question. The vertical asymptote is x=4/3 and the horizontal asymptote is y=2/3

When the graph of a function lies very close to the axis and extends to infinity it is called an asymptote. Vertical asymptote is a vertical line that directs but does not form a part of the graph of a function. Horizontal asymptote is a horizontal line that shows how the function behaves at extreme edges. Horizontal asymptote exists for functions whose numerator and denominator have same degree or degree of numerator is less than numerator of denominator.

f(x)=2x-7/3x-4

The horizontal asymptote of the function can be given by dividing the leading coefficients.

HA=2/3

The vertical asymptote can be found by equating the denominator to zero.

3x-4=0

x=4/3

Therefore the horizontal asymptote is y=2/3 and the vertical asymptote is x=4/3.

What is a quadratic equation?

A quadratic equation is an algebraic equation that has highest degree of 2, therefore, it also has two roots or we can say it has two solutions.

We know sign distributions that negative distributed to a negative is positive and positive distributed to a positive also results in positive.

∴ 9 can be obtained by either multiplying (-3)(-3) or (3)(3).

a jet plane traveling at 480 mph overtakes a propeller plane traveling at 200 mph that had a 3 hour head start. how far from the starting point are the​ planes?

Answers

The distance of both the planes from the starting point will be  1029 miles.

This is a question of time, speed and distance.

Given that:-

Speed of jet plane = 480 mph

Speed of propeller plane = 200 mph

Also, the propeller plane has a 3 hour head start.

We have to find the distance of both the planes from the starting point.

When the jet plane overtakes the propeller plane both of them would have covered the same distance.

Let the time taken by the jet plane to overtake the propeller plane be t hours.

Hence, the propeller plane would have travelled for (t+3) hours.

Hence, we can write,

480*t = 200*(t+3)

480t = 200t + 600

280t = 600

t = 600/280 = 15/7 hours.

Hence, distance from both the planes from the starting point = (15/7)*480 = 1028.57 miles = 1029 miles.

The length and width of a rectangle are consecutive odd integers. The perimeter of
the rectangle is 80 centimeters. Find the length and width of the rectangle.

Answers

The length of the rectangle = 21 cm

and the width of the rectangle = 19 cm

In this question, the length and width of a rectangle are consecutive odd integers.

Let n, n + 2 be the width and the length of a rectangle.

The perimeter of the rectangle is 80 centimeters.

Using the formula of the perimeter of the rectangle ,

P = 2 × [n + (n + 2)]

80 =  2(2n + 2)

40 = 2(n + 1)

20 = n + 1

n = 19

This means, the width of the rectangle is 19 centimeters.

And the length = n + 2

                         = 19 + 2

                         = 21 cm

Therefore, the length of the rectangle = 21 cm

and the width of the rectangle = 19 cm

The points T, U, V and W all lie on the same line segment, in that order, such that the ratio of TU:UV:VWTU:UV:VW is equal to 1:5:2.1:5:2. If TW=32,TW=32, find UW.UW.

Answers

Answer:

The length of UV is 10 units.

Step-by-step explanation:

It is given that the points T, U, V and W all lie on the same line segment, in that order, such that the ratio of TU:UV:VW is equal to 1:5:2.

Now, we need to calculate UW if TW = 32.

So, TU : UV : VW = 2 : 5 : 5

=> TW = 24

From the above conditions it can be observed that;

=> Ratio of TU = 2

=> Ratio of UV = 5

=> Ratio of VW = 5

Firstly, we have to sum up the total ratio that is;

=> Total = Ratio of TU + Ratio of UV + Ratio of VW

=> Total = 2 + 5 + 5

=> Total = 12

Now, we need to calculate the length of UV from which we get;

=> UV = 5/12 * 24

=> UV = 10

Therefore; length of UV is 10 units.

Tom Harris is twenty-four years old. He wishes to purchase $7,000 of a ten-year term insurance. What will be his annual premium?

Answers

The annual premium of Tom Harris is $29.05

What is annual premium?

Annual premium is the amount of money that policyholder has to pay in a policy year.

Annual formula = (face value of policy per $1000)* (rate of insurance)

Given that Tom Harris is twenty four years old man want to purchase a $7000 for a ten year term insurance.

From the given table we can say that the rate of insurance for a 24 year old man per $1000 for a 10 year terms is 4.15

Face value of insurance = $7000

Face value of insurance per $1000 = 7000/1000 =$7

Then the annual premium = $7 * 4.15 =$ 29.05

Therefore, the annul premium paid by Tom Harris is $29.05

If B is collinear and between points A and C, then the value of x is 5 and the value of AC is 50.

Collinear points refers to the points that lies on the same straight line.

If B is collinear with points A and C, and lies between them, then the sum of the distance from A to B and the distance from B to C is equal to the distance from A to C.

AB + BC = AC

How to find the terms of a sequence?

Each term of the sequence is 2 more than the previous term.

The third term is 8.

The sequence is an arithmetic sequence base on the difference.

Using arithmetic sequence formula,

aₙ = a + (n - 1)d

where

a = first termd = common differencen = number of terms

Therefore, let's used the third term to find the first term.

8 = a + 2d

8 = a + 2(2)

8 = a + 4

a = 8 - 4

If 3(x-2)= 2x+6 then x equals?

Answers

Answer:

x = 12

Step-by-step explanation:

First, distribute the 3 into the parentheses:

3(x-2) = 2x+6 ----> 3x-6 = 2x+6

Next, combine like terms by adding 6 to both sides of the equation:

3x-6 = 2x+6 ----> 3x = 2x+12

Then, subtract 2x from both sides:

3x = 2x+12 ----> 1x = 12

Finally, divide both sides by 1 to get x by itself:

x = 12

There were ___ buses.
There were ___ vans.

Answers

The number of vans and buses conveying the students to the field trip is 3 and 19 respectively

How to solve number of buses and Vans simultaneously

let

number of van = xNumber of bus = y

x + y = 19

7x + 25y = 421

From (1)

x = 19 - y

Substitute x = 19 - y into (2)

7x + 25y = 421

7(19 - y) + 25y = 421

133 - 7y + 25y = 421

- 7y + 25y = 421 - 133

18y = 288

y = 288/18

y = 16

Substitute y = 16 into (1)

x + y = 19

x + 16 = 19

x = 19 - 16
