Answer:

x=1 and y=4

Step-by-step explanation:

Let's solve your system by substitution.

3x−6y=−21;6x−9y=−30

Step: Solve3x−6y=−21for x:

3x−6y=−21

3x−6y+6y=−21+6y(Add 6y to both sides)

3x=6y−21

x=2y−7

Substitute2y−7for x in6x−9y=−30:

6x−9y=−30

6(2y−7)−9y=−30

3y−42=−30(Simplify both sides of the equation)

3y−42+42=−30+42(Add 42 to both sides)

3y=12

y= 4

Substitute4foryinx=2y−7:

x=2y−7

x=(2)(4)−7

x=1(Simplify both sides of the equation)

[tex]a^7-7a^6b+21a^5b^2-35a^4b^3+35a^3b^4-21a^2b^5+7ab^6-b^7[/tex]

Step-by-step explanation:

There are multiple ways of expanding a polynomial expression to a high degree. One way of doing it is to write out the problem in the multiplication form, multiply (a - b) by itself (7) times.

[tex](a-b)^7[/tex]

[tex]=(a-b)(a-b)(a-b)(a-b)(a-b)(a-b)(a-b)[/tex]

Now simplify, multiply two terms together,

[tex]=(a^2-2ab+b^2)(a^2-2ab+b^2)(a^2-2ab+b^2)(a-b)[/tex]

Repeat this process,

[tex]=(a^4-4a^3b+6a^2b^2-4ab^3+b^4)(a^3-3a^2b+3ab^2-b^3)[/tex]

Repeat this process one final time,

[tex]a^7-7a^6b+21a^5b^2-35a^4b^3+35a^3b^4-21a^2b^5+7ab^6-b^7[/tex]

Answer:

15

Step-by-step explanation:

We know that the expression is equal to 110° since it is a vertical angle. So what we do is we ad 10 to both sides of the equation. We are left with 8x=120 so if we divide 120/8 we get 15 which would leave it as x=15. Now plug it in and check it.

Answer:

6. r=2

8.x=3

Step-by-step explanation:

6. 4r-3=5

4r-3=5 add 3 to both sides

4r=8 divide 4 by both sides

r=2

8. 5x-6=9

5x-6=9 add 6 to both sides

5x=15 divide 5 by both sides

x=3

Answer:

D

Step-by-step explanation:

Answer:

The answer is D

Step-by-step explanation:

If you simply add a negative sign to the x coordinate, you get the reflected point.

Given:

The given data set are:

8,12,14,14,20

8,12,14,14,22

9,13,14,15,19

All of the above

To find:

The set of data that has the highest interquartile range(IQR).

Solution:

We know that, the interquartile range(IQR) of a data set is the difference between the third quartile and first quartile.

[tex]IQR=Q_3-Q_1[/tex]

All the given data set has five values in ascending order. So, the first value is the minimum value, second value is the first quartile, third value is the median, the fourth value is the third quartile and the fifth value is the maximum value.

For 8,12,14,14,20,

[tex]IQR=14-12[/tex]

[tex]IQR=2[/tex]

For 8,12,14,14,22,

[tex]IQR=14-12[/tex]

[tex]IQR=2[/tex]

For 9,13,14,15,19,

[tex]IQR=15-13[/tex]

[tex]IQR=2[/tex]

All interquartile ranges are equal. So, all the data sets has t he highest interquartile range.

Therefore, the correct option is D.

Answer:

Step-by-step explanation:

5/7 x 9/10

=5/7 9/5 X 2

=1/7 X 9/2

=1 X 9/ 7 X 2

=9/ 7 X 2

=9/14

The expression 5/7 x 9/10, is equivalent to 9/14.

We have the following expression -

5/7 x 9/10

Given is -

5/7 x 9/10

1/7 x 9/2

9/14

Therefore, the expression 5/7 x 9/10, is equivalent to 9/14.

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]Total = x^2 + 14x + 24[/tex]

[tex]Area\ I = x^2[/tex]

[tex]Area\ IV = 24[/tex]

Required

True about area II and III

The question is incomplete; so, I will answer using general knowledge.

If the total area is:

[tex]Total = x^2 + 14x + 24[/tex]

And there are 4 areas, then;

[tex]Total = Area\ I + Area\ II + Area\ III + Area\ IV[/tex]

Rewrite as:

[tex]Total = Area\ I + Area\ IV+ Area\ II + Area\ III[/tex]

This gives:

[tex]x^2 + 14x + 24 = x^2 + 24+ Area\ II + Area\ III[/tex]

Collect like terms

[tex]x^2 -x^2 + 14x + 24 -24= Area\ II + Area\ III[/tex]

[tex]14x = Area\ II + Area\ III[/tex]

Rewrite as:

[tex]Area\ II + Area\ III = 14x[/tex]

So, the sum of areas III and IV must be 14x

Answer:

Ahmed got 390 votes

Step-by-step explanation:

Here, we want to know the number of votes obtained by Ahmed

from the question, there were 900 registered voters

10% did not cast their votes

The number that didn’t cast their votes will be;

10% of 900

= 10/100 * 900 = 90

So the rest 90% casted and this value will be 900-90 = 810

810 people casted their votes

30 votes were spoilt;

The number of valid votes is thus;

810 - 30 = 780

Ahmed got a ratio of 3 in 3:2:1

The total value here is 3 + 2 + 1 = 6

So what Ahmed got will be;

3/6 * 780

= 780/2 = 390

Answer:

This is a matter of ratio and proportion, let us represent the unknown value as x. Since the two ratios are related,

40 : 180 :::: x : 900

40 / 180 = x / 900

Answer:

the second choice 6/200

Step-by-step explanation:

Answer:

If two angles in standard position have the same terminal side, they are called coterminal angles.

The reference angle is the acute angle (the smallest angle) formed by the terminal side of the given angle and the x-axis.

Angle of Rotation is the measurement of the amount of the angle, by which a figure is rotated counterclockwise about a fixed point, often the center of a circle. Usually clockwise rotation is called as Negative rotation

If two angles in standard position have the same terminal side, they are called coterminal angles.

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

Coterminal angles are those angles that share the terminal side of an angle occupying the standard position. The standard position means that one side of the angle is fixed along the positive x-axis, and the vertex is located at the origin.

The reference angle is the acute angle (the smallest angle) formed by the terminal side of the given angle and the x-axis.

Angle of Rotation is the measurement of the amount of the angle, by which a figure is rotated counterclockwise about a fixed point, often the center of a circle. Usually clockwise rotation is called as Negative rotation.

Hence, if two angles in standard position have the same terminal side, they are called coterminal angles.
