The answer is that you have to have Addition and division to solve this equation

Answer: Dividing by 4 is the inverse of multiplying by 4

Step-by-step explanation:

We notice that when x increases by 3, y decreases by 2.

Hence the slope of the line

= Rise of y / Run of x

= (-2) / (3)

= -2/3.

Answer:

71°

Step-by-step explanation:

ABD is alternate to DEB. Therefore ADB = DEB = 71°

The required size of angle ABD is 71.

The theorem states that “For any circle, the angle formed between the tangent and the chord through the point of contact of the tangent is equal to the angle formed by the chord in the alternate segment”.

Now it is given that,

angle DEB = 71

Also given that B is the point on the circumference of the circle, and suppose “O” be the centre of the circle.

Now, AC is the tangent of the circle that passes through point B.

The tangent makes an angle ABD with the chord BD.

Now, given that ∠DEB = 71 in the alternate segment.

Now, we have to prove that ∠ABD = 71.

Thus, OD =OB (Both are the radii of the circle)

Also, ∠ODB = ∠OBD (since the angles opposite to the equal sides are equal)

Since, OBD is an isosceles triangle

∠BOD = 180° – ∠ODB – ∠OBD

∠BOD = 180° – 2∠OBD …(1)

Since, the line segment AC is the tangent line,

∠OBA = 90°

Therefore, ∠OBA = 90° – ∠OBD …(2)

From the equations (1) and (2), we can write

∠AOB = 2∠DEB

We know that the angle at the centre of the circle is twice the angle at the circumference of the circle.

∠BOD = 2∠DEB

∠DEB = (½)∠BOD

Now, substitute ∠BOD = 2∠DEB  in the above equation, we get

∠DEB = (½)2∠DEB

∠DEB = ∠DEB

⇒ ∠DEB =71

Thus, the required size of angle ABD is 71.

Answer:

Equation of the line is: [tex]x=6[/tex]

Step-by-step explanation:

We know that , the equation of any line parallel to y axis is :

[tex]x=k[/tex]    where [tex]k[/tex] ia a constant

And here it is given that the line is passing through the point P(6,-3)

Therefore, it will satisfy the equation [tex]x=k[/tex].

So, substitute [tex](6,-3)[/tex] in equation [tex]x=k[/tex], we get

[tex]k=6[/tex]

Hence the equation of line will be [tex]x=6[/tex]

Answer:

Daughter is 25, mother is 58

Step-by-step explanation:

Let m = age of mother now

Let d = age of daughter now

m - 14 = 4(d - 14)

m = 2(d + 4)

m - 14 = 4d - 56

m = 2d + 8

subtracting them gets

14 = -2d + 64

2d = 50.

d = 25

m = 58

Answer:

The surface area of the prism is 48 units².

Step-by-step explanation:

Remember, a net is simply the outer surface of a 3D shape flattened and spread out as a combination of 2D shapes.

With this info, the rest is relatively easy.

The net shows that there are 4 rectangular sides and 2 square sides. We also know the lengths and widths of all of them.

One rectangle is 5 units long and 2 units wide. One square is 2 units long and 2 units wide.

Let's put this into an equation.

4( 5*2 ) + 2( 2*2)

We are adding the areas of the rectangles and squares.

So, let's simplify that equation.

4(10) + 2(4)

40 + 8

The  scale factor of the dilation of line segment BA is 5.

To adjust the size of a figure without altering its shape, a scale factor is a number or conversion factor that is utilised. It is employed to change the size of an object. If the original figure's dimensions and the dilated (increased or lowered) figure's dimensions are known, the scale factor can be determined.

When both the original dimensions and the new dimensions are known, the scale factor may be determined. When employing the scale factor, there are two terms that must be understood. When a figure's size is increased, we refer to this as scaling up, and when its size is decreased, we refer to this as scaling down.

Given:

AC= 4

AA' = 16

and, A'C= 16+ 4 = 20

So, scale factor = AC/ A'C

                          = 4/5

                          = 1/5

Hence, the scale factor of the dilation of line segment BA is 5.
