Answer:

x=-9/2, -2

Step-by-step explanation:

2x+9=0 subtract 9 and divide by 2 to isolate x.

x=-9/2

(writing a 1 in front of the x is unnecessary)  x+2=0 subtract 2 to isolate x.

x=-2

Answer:

x=45°

Step-by-step explanation:

Since the angle is acute it's half of a right angle.

Right Angle is 90°

So u divide the right angle By 2 (90°÷2) You would get 45°

(6x4)-2

multiply the number of vans by the number of player in each van which equals 24 then subtract the 2 goal keepers which equals 22.

Answer:

The third option

Step-by-step explanation:

If you plug -4 in for x in the first option, you would get 12 +  which is 14 and

14 ≠ 5.

If you plug in -4 for the second option you would have -0.75 times -4 which is 3 and 3 plus 8/3 would not give you a whole number so it is not equal to 5.

If you plug in -4 to the third option you would get -4 times -0.75 which is 3 and 3 + 2 = 5. But to check the rest of the numbers you would plug in 0 for x and get -0.75 times 0 is 0 and 0 + 2 = 2.

For the last option, just to eliminate all other options, if you plug in -4 for x you would have 2 times -4 which is -8 and -8 - 0.75 would not be a whole number so it could not be 5.

Answer:

2d-5

Step-by-step explanation:

Take out or divide everything in the expression by -4

So, (-8d+20) ÷ -4 = 2d-5

To check your answer, multiply:

-4 × (2d-5) = -8d+20

The linear expression in one variable -8d + 20 can be written as -4(2d - 5) after factoring -4 from it.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The linear expression in one variable is:

= -8d + 20

Here d is the variable

Taking common as - 4 from the linear expression:

= -4(2d - 5)

Thus, the linear expression in one variable -8d + 20 can be written as -4(2d - 5) after factoring -4 from it.

Answer: 3-4log₃(x)

Step-by-step explanation:

the biggest error

if it is a division of log we have to subtract

log₃(27)-lox₃(x^4)=3-4log₃(x)

Answer:

y is 31

Step-by-step explanation:

we need to substitute first

x + y = 10

x= -21 so...

-21 + y = 10

now we need to add 21 on both sides of the equation, we are adding because  21 because we want that 21 gone, and it's the oppisite of subtracting

-21 + 21 + y = 10 + 21

0 + y = 10 + 21

y= 31

Check:

x+y=10

-21 + 31= 10

10 = 10 correct!

Hope this helped!

We are told that the coordinates of the image are of the formula:

P'(x-2 , y-3) where x and y are the actual points and x-2 and y-3 are the reflections

Finding the coordinates of point A:

We are given that the coordinates of reflection of A are: A'(-4 , 3)

we also know that reflected point follow the formula: P'(x-2 , y-3)

So, the points of A'(-4 , 3) follow the formula P'(x-2 , y-3)

So, their respective x and y coordinates will be equal

Hence,

x - 2 = -4

x  = -2                 [adding 2 on both sides]

Also,

y - 3 = 3

y  = 6                 [adding 3 on both sides]

Therefore, the coordinates of A are A(-2,6)

Finding the coordinates of B:

We are given the coordinates of B' are B'(-4 , 2)

So,

x - 2 = -4

x = -2             [adding 2 on both sides]

also,

y-3 = 2

y = 5             [adding 5 on both sides]

Therefore, the coordinates of B are: B(-2,5)

Finding the coordinates of C:

We are given that the coordinates of reflection of C are: C'(-2,3)

Using the general formula given in the question:

x - 2 = -2  

x = 0            [adding 2 on both sides]

y - 3 = 3

y = 6            [adding 3 on both sides]

Therefore, the coordinates of C are: C(0,6)

Finally, the coordinates of A, B and C are:

A(-2,6)   ,    B(-2,5)   ,    C(0,6)

Reflecting the pre-image along the x-axis

To reflect along x-axis, we multiply the y-coordinate by -1

Coordinates of the pre-image:

A(-2,6)   ,    B(-2,5)   ,    C(0,6)

Coordinates of points reflected along the x-axis:

A(-2,-6)   ,    B(-2,-5)   ,    C(0,-6)

Answer:

"a Sample Statistic"

Step-by-step explanation:

A sampling distribution is defined as the probability distribution of "a statistic" drawn from a large number of samples gotten from a specific population. In order words, it is a sample statistic.

Thus, the correct answer is "a Sample Statistic"

The sampling distribution is the probability of a particular report based on random sampling; it displays the most likely values of various sample means

It is a probability distribution of data mining, which is the process of analyzing larger samples gathered from a given population.  

In this, a particular population is the distribution of frequencies of a variety of possible outcomes for a population statistic.

It is the distribution of the probability for a statistic is generated from a large number of samples gathered from a certain population.

Therefore, "The sampling distribution is the probability of a particular report based on random sampling; it displays the most likely values of various sample means".

Answer:

2.6364

Step-by-step explanation:

Answer:

Total children = 52

Step-by-step explanation:

The question says that "The ratio of boys to girls in the school play is 5 to 8. There are 32 girls participating in the play. How many children participate in the school play? "

Let there are 5x boys and 8x girls in a school play.

Total no of girls participating in the play = 32

ATQ,

8x = 32

x = 4

Boys = 5x

= 5(4)

= 20

Total children = boys + girls

= 20 + 32

= 52

Hence, there are 52 children participating in the school play.

Answer:

  x = √66

Step-by-step explanation:

In a geometry like this, the right triangles are all similar. Then the length of the long side to the hypotenuse is ...

  6/x = x/(6+5)

  6·11 = x²

  x = √66

_____

Additional comment

The relation g=√(ab) gives the geometric mean (g) of the two numbers 'a' and 'b'. In this geometry, there are three geometric mean relationships.

  long side = geometric mean(long segment, hypotenuse) . . . x = √(6·11)

  short side = geometric mean(short segment, hypotenuse) . . . y = √(5·11)

  altitude = geometric mean(long segment, short segment) . . . BD = √(6·5)
