Answer 1

Answer:  x = 1,  y = -1

Step-by-step explanation:

The elimination method is a technique for solving systems of linear equations.

1) 4x-6y=10

2) 9x+2y=7

in the second equation

it multiply with 3

then

3×(9x+2y=7)

= 27+6y= 21

We notice that the first equation has a 6y term and the second equation has a -6y term. These terms will cancel if we add the equations together—that is, we'll eliminate the x terms:

then add 1 + 2 equations

    4x-6y =  10 _____1)

   27+6y= 21   _____2)

then we will get

    31x+0  =  31

     31x= 31

     where x = 31/31= 1

          then x = 1

      if value of  x substitute in the equation ____1)

                           4x+6y =  10

                           4×1+6y =  10

                            6y = -6

                            y = -6/6

                             y = -1

Carly is in an air balloon. When Carly is at a height of 21.6 meters (m)
she looks down to notice that the top of a tree is in the center of a large reflection pond in a garden. Upon returning to the ground Carly made a sketch, as shown.




Carly determined that horizontal distance, BD, the air balloon was from the base of the tree
was 30.24m and that the base of the tree was 12.96m from the center of the reflection pond.
What is the height, in meters, of the tree, KD? If necessary, round to the nearest hundredth.

Answers

Using the Pythagoras theorem, the height of the tree from the reflection pond is obtained as 27.3 m.

What is the height of the tree?

We know that the height of the tree can be obtained from the formula for the Pythagoras's theorem and looking at the theorem, we are going to have that;

C^2 = A^2 + B^2

Where A is the  height, in meters, of the tree.

Then we have that;

30.24^ = A^2 + 12.96^2

A^2 = 30.24^2 - 12.96^2

A =27.3 m

This is the length of the tree that have been measured from the ground to the given height as we have bene shown in the question above.

What are the slope and the y-intercept of the linear function that is represented by the table? x y the slope is , and the y-intercept is. The slope is , and the y-intercept is. The slope is , and the y-intercept is. The slope is , and the y-intercept is.

Answers

From the linear function that is represented by the table, we can conclude that the slope is -2, and the y-intercept is 12.

Linear function

The linear function is an equation for a line that can be written by finding the slope between two points on that line, then finding the y-intercept by using the slope-intercept equation: y=mx+b, where b represents the y value of the y-intercept point.

Now we take a look at the following data:

X     Y

–3   18

0    12

3     6

6     0

We want to know the slope by picking two out of four given points, let's say we pick the first two points:

y - y₀ = m (x - x₀)

(18 - 12) = m (-3 - 0)

6 = m * -3

m = 6 / -3

m = -2

Thus the slope is -2.

Now we substitute the slope value to one of the points, let's say we pick the first point:

(x₀, y₀) = (-3, 18)

y - y₀ = m (x - x₀)

y - 18 = -2 (x - (-3))

y = -2x - 6 + 18

y = -2x + 12

Thus the y-intercept of the linear function is 12.

What is the formula for finding the area of a triangle with an unknown height?

Answers

The formula for finding the area of a triangle with an unknown height is: Area = (Base * Height) / 2. This formula uses the base length of the triangle, multiplied by the height of the triangle, then divided by 2.

The formula for finding the area of a triangle with an unknown height is: Area = (Base * Height) / 2. This formula uses the base length of the triangle, multiplied by the height of the triangle, then divided by 2. To use this formula, start by determining the base length of the triangle. This is the length of any one side of the triangle. Once the base is determined, use the formula to calculate the area. In the formula, the base is multiplied by the height of the triangle. Since the height is unknown, use the Pythagorean Theorem to calculate it. The Pythagorean Theorem states that the square of the hypotenuse (the longest side of the triangle) is equal to the sum of the squares of the other two sides. Once the hypotenuse is known, the height can be found by using the formula (Height = Hypotenuse - Base) / 2.

How do you find the center of a dilation of two shapes?

Answers

A fixed point in the plane around which all points are enlarged or contracted is the centre of a dilation. The centre, which may be found within, outside, or on a figure, is the only invariant (not changing) point under a dilation (k 1).

What is Centre of Dilation?

A Dilation of an image in mathematics refers to a change that results in an image with the same shape but a different size, either larger or smaller. A dilation can only be built with two bits of information.

The scale factor determines how much the dilated image is enlarged or reduced in size in relation to the original. A positive scale factor is required. When the scale factor exceeds 1, the dilation becomes an expansion. If it falls within the range of 0 and 1, the dilation is a contraction.

The point from which the image is dilated is known as the centre of dilatation (or point of dilation).

Properties of Dilation

Following are some shape characteristics that aren't altered by the dilation transformations:

The figure's angles are all the same.The figure's midpoints are the same as the midpoint of the dilated shape.The parallel and perpendicular lines in the illustration are identical to those in the dilated illustration.The pictures stay the same.The distance between the spots is the only thing that changes during the dilation process. It implies that the sides of the original and dilated images may differ in length. Dilation processes come in two different varieties. As follows:

Horizontal Dilation

The dilation transformation of a function y=f(x) is dilated horizontally by a scale factor C is

Y = f(Cx)

This kind of transformation is called a horizontal dilation.

Vertical Dilation

The dilation transformation of a function y=f(x) is dilated vertically by a scale factor C isY = C * f(x)

This kind of transformation is called a Vertical dilation.

Centre of Dilation of a Polygon

The ratio of matching side lengths is the scale factor of a dilatation. The origin will always be the centre of dilatation in this course. You can enlarge a polygon by connecting its vertices while multiplying each vertex's coordinates by the scale factor k.

A $125 art set is on sale for 30% off. What is the final purchase price if there is an 8% sales

Answers

The final purchase price would be $81.20.

What is sale?

Sale is an act of exchanging goods or services for money. It is a business transaction in which a seller transfers the ownership of goods or services to a buyer in exchange for money. Sale can be done in a variety of ways, such as through retail stores, online stores, auctions, or even by bartering. Sale is one of the most important aspects of any business and is the primary way businesses make money.

This includes the 30% discount, which reduces the original price of the art set from $125 to $87.50, plus the 8% sales tax,

which adds an additional $6.70 to the total.

Answers

The equation which has been given is a linear equation, therefore in order to solve the equation, simply the basic mathematical operation is to be performed. The acquired value of x is not the same as the value. So, when 12=13.x+5, the value of x=21 is not true.

Given information:

The equation given in the question is: 12 = 3x + 5

The value of x=21

Perform the basic mathematical operations and find the value of a variable.

  13x + 5 =12

⇒13x = 12 -5

⇒ 13x = 7

⇒ x = 7/13

⇒ x = 0.538

The acquired value of x is not the alike as the given value.

Hence, when 12=13.x+5 the value of x=21 is not true.

0.3125

Answers

The Probability of P(at least 3 tails) is 0.3125.

The correct option is (D).

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Total outcome= 16

Now, P( less than 3 tails)= 11 /16

So, P(at least 3 tails) = P( x ≥ 3)

= 1 - P(x < 3)

= 1- 11/ 16

=  5/16

= 0.3125

Hence, the Probability is 0.3125
