Answer:

Q1. [tex](-\frac{3}{2},0)[/tex]

Q2. (-16, 0)

Step-by-step explanation:

The midpoint of a line segment is given by the formula:

[tex]\boxed{\text{Midpoint}=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )}[/tex]

In the formula, [tex](x_1,y_1)[/tex] is the first endpoint while [tex](x_2,y_2)[/tex] is the second endpoint of the line segment.

__________

Q1. Substitute the given endpoints into the formula:

Midpoint

[tex]=(\frac{-5+2}{2} ,\frac{5-5}{2} )[/tex]

[tex]=(\frac{-3}{2} ,\frac{0}{2} )[/tex]

[tex]= \bf{(-\frac{3}{2} ,0)}[/tex]

__________

Q2. Let the other endpoint be (x, y).

Substitute the given midpoint and one endpoint:

(-6, 4)=[tex](\frac{x+4}{2} ,\frac{y+8}{2} )[/tex]

Comparing the x-coordinate:

[tex]\frac{x+4}{2} =-6[/tex]

Multiply both sides by 2:

x +4= -12

Subtract 4 from both sides:
x= -12 -4

x= -16

Comparing the y-coordinate:

[tex]\frac{y+8}{2} =4[/tex]

Multiply both sides by 2:

y +8= 8

Subtract 8 on both sides:

y= 8 -8

y= 0

The coordinates of the other endpoint is thus (-16, 0).

Step-by-step explanation:

your own work, please ...

my own work is

1.

the midpoint between 2 points (x1, y1) and (x2, y2) is

((x1 + x2)/2, (y1 + y2)/2)

so, our midpoint is

((-5 + 2)/2, (5 + -5)/2) = (-3/2, 0/2) = (-3/2, 0)

2.

we have

((x1 + 4)/2, (y1 + 8)/2) = (-6, 4)

so,

(x1 + 4)/2 = -6

x1 + 4 = -12

x1 = -16

(y1 + 8)/2 = 4

y1 + 8 = 8

y1 = 0

so, the other endpoint is (-16, 0).

Answer:

14x - 12y

Step-by-step explanation:

Let's write the sum:

(10x - 4y) + (4x -8y)

Because we're only doing addition and subtractaction, we can drop the  parentheses that aren't preceded by a minus sign, they don't change the order.

10x - 4y + 4x - 8y

as long as we don't change the sign preceding each component, we can reorder as we wish

10x + 4x - 4y - 8y

(10x + 4x) - (4y + 8y)

note that because we added a parenthesis preceded by a - the sign inside changed.

We perform additions inside of the parentheses:

10x + 4x = 14x

4y + 8y = 12y

and we arrive at the final result:

14x - 12y

He can buy 4 books with 2 dollars remaining

Step-by-step explanation:

30/7 = 4 R2

Answer: 4 books.

Explanation: First you divide $30 by 7, and you get 4 and 2/7 (2/7 as the remainder) left over. So you can't have 4 and 2/7 books, it has to be a whole number.

Therefore, he can buy 4 books. I hope this helped!

Answer:

the answer is 99

Step-by-step explanation:

simply multiple 24 3/4 by 4

Answer:

99 miles per hour

Step-by-step explanation:

(24 3/4) / (1/4) =

99/4 x 4/1 =

396/4 = 99

First, find the equation

y = F(x) = x +3

Then plug in 2 for x ( you could also go to 2 on the x-axis to find the Y)

F(2) = (2)+3

F(2) = 5

For f(g(x)) it's f(5x+9)=2r-7

For g(f(x)) it's g(2r-7)=5x+9

Answer:

[tex]r=\sqrt{\dfrac{3V}{\pi h}}[/tex]

Step-by-step explanation:

The formula for the volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]

Where

r is radius of cone and h is its height

We need to solve the above formula for r.

Cross multiplying both sides of the given formula

[tex]3V=\pi r^ 2h[/tex]

Dividing both sides by πh.

[tex]\dfrac{3V}{\pi h}=\dfrac{\pi r^2 h}{\pi h}\\\\r^2=\dfrac{3V}{\pi h}\\\\r=\sqrt{\dfrac{3V}{\pi h}}[/tex]

So, the formula for r is [tex]\sqrt{\dfrac{3V}{\pi h}}[/tex]

The value of x after simplfication of equation -¼ ( x + 2) + 5 = - x is -6.

Consider the equation,

( - 1 / 4 ) × ( x + 2 ) + 5 = - x

Now,

( - x / 4 ) + ( - 2 / 4 ) + 5 = - x

( - x / 4 ) - ( 1 / 2 ) + 5 = - x

Now, LCM of 2 and 1 is 2.

Therefore,

( - x / 4 ) + [ ( 10 - 1 ) / 2 ] = - x

( - x / 4 ) + ( 9 / 2 ) = - x

Adding x on both sides of the equation.

( - x / 4 ) + x + ( 9 / 2 ) = - x + x

Subtracting ( 9 / 2 ) from each side of the equation,

( - x / 4 ) + x + ( 9 / 2 ) - ( 9 / 2 ) = ( - 9 / 2)

( - x / 4 ) + x = ( - 9 / 2 )

LCM of 4 and 1 is 4

[ ( - x + 4x ) / 4 ] = ( - 9 / 2 )

( 3x / 4 ) = ( - 9 / 2 )

By cross multiplying,

2 × 3x = - 9 × 4

6x = - 36

Dividing each side of the equation by 6.

( 6x / 6 ) = ( - 36 / 6 )

x = - 6

Positive Integer

Step-by-step explanation:

An integer is a whole number.

462 is an integer and is positive.

Answer: positive integer

Step-by-step explanation:

Kinda obvious

Answer:

Step-by-step explanation:

An absolute value is the distance a number is from 0 on the number line. So, regardless if it is a negative or a positive number, the distance from that number to 0 will always be positive. For example, -5 is 5 units away from 0, and 5 is also 5 units from zero. They have the same absolute value, even though one is negative and the other is positive.

Answer:

You can describe absolute value as a number's (Negative or positive) distance from zero.

Step-by-step explanation:

Say you have 4 and -4. 4's absolute value is four because it is four number units away from zero. -4 is a negative number but its absolute value would still be positive four because it is still four number units away from zero even though those number units are negative.

The equation to find what Fred's allowance is will be 0.5x + 20 = 30

Let the variables be x.

From the information, Fred spent half of his allowance on a game at Target. Then he earned an extra $20 by mowing his grandparents’ lawn. After he did this, he had $30 left.

This will be:

(1/2 × x) + 20 = 30

0.5x + 20 = 30

Therefore, the equation to find what Fred's allowance is will be 0.5x + 20 = 30
