Answer:

-4 - 2x

Step-by-step explanation:

To solve the expression 4-2(x+4) we will first need to make all signs reasonable:

4 - 2(x+4)

4 + (-2)(x+4)

Next we will need to distribute the -2 out since it is being multiplied:

4 + (-2x) + (-2)(4)

4 + (-2x) + (-8)

Lastly we will combine like terms:

4 + (-2x) + (-8)

-4 + (-2x)

-4 - 2x

Considering there are no other like terms or multiplication, our final expression is -4 - 2x

                                        Question 9

Given the segment XY with the endpoints X and Y

Given that the ray NM is the segment bisector XY

so

NM divides the segment XY into two equal parts

XM = MY

given

XM = 3x+1

MY = 8x-24

so substituting XM = 3x+1 and MY = 8x-24 in the equation

XM = MY

3x+1 = 8x-24

8x-3x = 1+24

5x = 25

divide both sides by 5

5x/5 = 25/5

x = 5

so the value of x = 5

As the length of the segment XY is:

Length of segment XY = XM + MY

                                = 3x+1 + 8x-24

                                = 11x - 23

substituting x = 5

                               = 11(5) - 23

                               = 55 - 23

                               = 32

Therefore,

The length of the segment = 32 units

                                        Question 10)

Given the segment XY with the endpoints X and Y

Given that the line n is the segment bisector XY

so

The line divides the segment XY into two equal parts at M

XM = MY

given

XM = 5x+8

MY = 9x+12

so substituting XM = 5x+8 and MY = 9x+12 in the equation

XM = MY

5x+8 = 9x+12

9x-5x = 8-12

4x = -4

divide both sides by 4

4x/4 = -4/4

x = -1

so the value of x = -1

As the length of the segment XY is:

Length of segment XY = XM + MY

                                = 5x+8 + 9x+12

                                = 14x + 20

substituting x = 1

                               = 14(-1) + 20

                               = -14+20

                               = 6

Therefore,

The length of the segment XY = 6 units

Why do whole numbers raised to an exponent get greater well fractions raised to an exponent get smaller
adelina 88 [10]
Because when you raise an exponent on a fraction, it is basically dividing into itself.  Imagine 1/3 multiplied my 3 (Ans is 1), the fractions aren't whole numbers so when they multiply into another number, it uses division
