[tex]\sf \dfrac{{x}^{a \: (b - c)} }{ {x}^{b \: (a - c)} } \: \div \: \bigg \lgroup \dfrac{ {x}^{b} }{ {x}^{a} } \bigg \rgroup^{c} \: = \: 1[/tex]
[tex]\\[/tex]
Now,
[tex]\sf \dfrac{{x}^{ab \: - \: ac} }{ {x}^{ba \: - \: b c} } \: \div \: \bigg \lgroup \dfrac{ ({x}^{b} )}{( {x}^{a}) } \bigg \rgroup^{c} \: = \: 1[/tex]

[tex]\\[/tex]
We know that, When sign change from division to multiplication we should do reciprocal of next number.
Therefore we get,
[tex]\sf \dfrac{{x}^{ab \: - \: ac} }{ {x}^{ba \: - \: b c} } \: \times \: \dfrac{ {x}^{ac} }{{x}^{bc} } \: = \: 1[/tex]

[tex]\sf \dfrac{{x}^{ab \: - \: \cancel {ac }\: + \: \cancel{ac}} }{ {x}^{ba \: - \: \cancel{ b c} \: + \: \cancel{bc}} } \: = \: 1[/tex]

which point is the midpoint of AE
Point D is the midpoint of points A and E for the given number line.
What is a number line?A number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.
A horizontal number line is the most common representation and can be extended infinitely in any direction.
Given the number lines with labeled points as A, B, C, D, and E.
The midpoint of AE is the mean of AE
Mean of AE ;
(A + E )/ 2 = (- 6 + 8) / 2
2 / 2 = 1 which is point D
Therefore "D" will be the midpoint of A and E.
Hence "Point D is the midpoint of points A and E for the given number line".

1. What is a variable?
2. Solve the following equations:
3x + 6 - X + 82 = 44
Show your work for the equations.
A variable is a letter that represents another number or thing.
Steps to solve:
3x + 6 - x + 82 = 44
~Combine like terms
2x + 88 = 44
~Subtract 88 to both sides
2x = -44
~Divide 2 to both sides
x = -22

The area of the surface of the largest known star is about 1015 square miles. The area of the surface of the Earth is about 1011 square miles. How many times larger is the star's area?
Answer:
The surface area of the star is approximately 1.004 times larger than the earth's surface area
Step-by-step explanation:
To find the number of times b which the area of the star is larger than that of the earth, we will divide the area of the area of the star by the area of the earth.
Area of surface of star = 1015 square miles
Area of surface of the earth = 1011 square miles
∴ (Area of star) ÷ (Area of the earth)
= 1015 ÷ 1011 = 1.00395 times
Therefore the surface area of the star is approximately 1.004 times larger than the earth's surface area

Three copies of this rectangle were connected along a side to make a larger rectangle. What could the perimeter of the new rectangle be? Consider all possibilities.
Answer:
388in or 202in
Step-by-step explanation:
I decided to connect three copies of this rectangle, all along the right side of the rectangle in the picture above.
When this is done the new length along the bottom and top become 45×4=180.
Now to find the perimeter, 180+180+14+14=388in
Other possibility
Connect the three copies along the top.
Now we need to do 14×4=56, which is the new side length.
Now to find the perimeter, 56+56+45+45=202in

The quotient of 1/3 and 4/3
Answer:
1/ 4
Step-by-step explanation:
The question can also be written as [tex]\frac{1}{3} /\frac{4}{3}[/tex] .
Because it's division of fractions, you can multiply to find the answer by making 4/3 into 3/4. So
1/ 3 times 3/4 = 3/12 = 1/4
Answer:
if you're trying to find the quotient then the answer is: 4/9
if you're trying to add then the answer is: 5/3
if you're trying to divide then the answer is: 4/9
if you're trying to multiply then the answer is: 4/9
if you're trying to simplify then the answer is: 4/9

Answer:
(x+1)²=-1
Step-by-step explanation:
x²-7x=-9x-2
x²+2x+2=0
If you solved this using the quadratic formula, you’d end up with -1+i and -1-i.
but if you subtracted 1 from both sides, you’d have
x²+2x+1=-1
Which is:

Answer:
{ -2 if x ∈ -4 < x < -3

Step-by-step explanation:
From the graph, we have;

For the next inequality line at y = -5, we have;
1) The inequality line, starts with an open circle on the left at x = -3, which is equivalent to less than or equal to symbol, ≤ as -3 ≤ x because the point x =-3 is the left boundary. The inequality line extends to the point x = 2, where we have a closed circle (on the right), which is equivalent to a x ≤ 2 with the 2 on the right hand side because, the 2 is the right boundary of the inequality
2) The inequality can be summarized as starting from x = -3 extends to x = 2
3) As stated in point 1) the point x = 3, we have -3 ≤ x and at point x = 2, we have x ≤ 3 which can be combined as -3 ≤ x < 2, to give;
{ -5 if x ∈ -3 ≤ x < 2
For the next inequality line at y = 5, we have;
1) The inequality line, starts with an open circle on the left at x = 2, which is equivalent to less than or equal to symbol, ≤ as 2 ≤ x because the point x =2 is the left boundary. The inequality line extends to the right to reach point x = 5, where we have a closed circle (on the right), which is equivalent to a x ≤ 5 inequality, with the 5 on the right hand side because, the 5 is the right boundary of the inequality
2) The inequality can be summarized as starting from x = 2 extends to x = 5
3) As stated in point 1) the point x = 2, we have 2 ≤ x and at point x = 5, we have x ≤ 5 which can be combined as 2 ≤ x < 5, to give;
[ 5 if x ∈ 2 ≤ x < 5.
Answer:
1st box = [-4, -3]
2nd box = (-3, 2]
3rd box = (2, 5]
For f(x) = -2 we see that x is between -4 to -3 with closed endpoints.
So the interval will be [-4, -3].
For f(x) = -5 we see that x is between -3 to 2 with closed endpoint at 2 and open endpoints at -3.
So the interval will be (-3, 2].
For f(x) = 5 we see that x is between 2 to 5 with open endpoint at 2 and closed endpoint at 5.
So the interval will be (2, 5].
