What are parallel lines?
Parallel lines
Two lines are said to be parallel if on extending them indefinitely, they will never intersect
Transversal
Transversal is a line that intersects two or more parallel lines

line l ║ line m and line m ║ line n.
To prove line l║ line n
line l ║ line m
∠ABC = ∠ADE [Corrosponding angles are equal]
line m ║ line n.
∠ADE = ∠AFG [Corrosponding angles are equal]
So, ∠ABC = ∠AFG
So corrosponding angles of line l and line n are equal. So,

What is speed- distance formula?Speed, time, and distance relationships
Distance/Time x Speed This reveals how quickly or slowly an object is moving. It gives the amount of time it took to travel a certain distance divided by the distance travelled.Speed is inversely correlated with time and directly correlated with distance. Therefore, as the speed increases, the time required, because Time = Distance / Speed. Distance = Speed X Time.Each Speed, Distance and Time can be expressed in different units:
Time: seconds(s), minutes (min), hours (hr)Distance: (meters (m), kilometers (km), miles, feetSpeed: m/s, km/hrGiven:
distance= 5.2 m
speed= 4 m/ min
Now using
speed= Distance / time
4 = 5.2 / time
time= 5.2/4
time= 1.3 minutes.

Step-by-step explanation:
This question tests on the concept of percentages and comparing current and previous values.
Lets analyse the first statement from the question.
Taylor earned 15% more each week in September than in July.
We know that the formula for percentage change:
((Final Value - Initial Value) ÷ Initial Value) × 100
Comparing July and September,
we know that the change is 15% and the Final Value (September) is $207.
So we can substitute values into the formula to find the value for July.
[tex] \frac{207 - july}{july} \times 100 = 15 \\ \frac{207 - july}{july} = \frac{15}{100} \\ 207 - july = 0.15july \\ 1.15july = 207 \\ july = \frac{207}{1.15} \\ = 180[/tex]
Now we know Taylor earned $180 in July, we can use the same formula to find the amount she earned in August. Given Initial Value (July) = $180 and percentage change = 10% (She earns 10% more in August than in July)
[tex] \frac{sep - 180}{180} \times 100 = 10 \\ \frac{sep - 180}{180} = \frac{10}{100} \\ \frac{sep - 180}{180} = 0.1 \\ sep - 180 = 0.1 \times 180 \\ sep - 180 = 18 \\ sep = 18 + 180 \\ = 198[/tex]
Therefore, Taylor earns $198 per week in September.

p= principal amount, 0.12= the interest charged; p+0.12p=224 . write a problem based on the given information
Answers
Step 1: Let's review the information given to us to answer the problem correctly:
• p = Principal
,• 0.12 = Interest rate
,• 224 = Future value
Step 2: Let's write a problem based on this information, using the Simple Interest Formula, as follows:
A = P(1 + rt), where:
A = Final amount
P = Principal
r = Annual interest rate
t = Time in years
224 = P (1 + 0.12t)
224 = 1.12Pt
Pt = 224/1.12
Pt = 200
If P = 200, then t = 1

Find the value of x in the following equation:
3.6(2x + 5) = 7.2x + 18
No solution
Infinite solutions
x = 0
x = 2.3
Answers
The Linear equation 3.6(2x + 5) = 7.2x + 18.3 has no solution except when x is put to be zero.
The provided equation is 3.6(2x + 5) = 7.2x + 18.
This is a linear equation in one variable.
We have to solve the equation for x,
We can solve it by simplifying it,
3.6(2x + 5) = 7.2x + 18
7.2x + 18 = 7.2x + 18
7.2x = 7.2x
7.2x - 7.2x = 0
(7.2-7.2)x = 0
(0)x = 0
x =0/0
Hence, there can not be any value of x.
But, if we put x = 0 in the equation,
Then,
3.6(2(0) + 5) = 7.2(0) + 18
18 = 18
So, x = 0 is satisfying the equation.

a(1) = -4
Now that you have the first term you must find the fifth term by filling in 5 for n.
a(5) = 3(5) - 7
a(5) = 15 - 7

6. Work The dollar amount d that Julia earns varies directly as the number of hours !that she works, and d=$116.25 when 1 = 15 h. Find t when d = $178.25.
Answers
Answer:
t = 23
Explanation:
If the dollar amount d varies directly as the number of hours, t, the equation that relates these variables is
d = kt
Where k is a constant.
We know that for d = $116.25, t = 15 h, so we can replace these values and solve for k as follows
116.25 = k(15)
116.25/15 = k(15)/15
7.75 = k
Then, the equation that relates d and t is
d = 7.75t
Now, we know that d = $178.25 and we want to calculate t, so replacing d and solving for t, we get
178.25 = 7.75t
178.25/7.75 = 7.75t/7.75
23 = t
Therefore t = 23
The perimeter of a parallelogram is 72 meters . The width of the parallelogram is 4 meters less than its length. Write an equation that could be used to find the length of the parallelogram.
Answers
4L = 64
Explanation: The perimeter of a parallelogram (like most other quadrilaterals) is defined as;
P = 2 (L + W)
Where P is the perimeter, L is the length and W is the width. Note that the width is given as 4 metres less than its length, hence if the length is L then the width shall be L-4. The perimeter can now be expressed as follows:
P = 2 (L + [L-4])
If the perimeter is 72, then
72 = 2 (L + L - 4)
72 = 2 (2L - 4)
By expanding the bracket on the right hand side we now have;
72 = 4L - 8
Add 8 to both sides of the equation
72 + 8 = 4L - 8 + 8
80 = 4L
Therefore the equation is 4L = 80
And the Length is 20 metres.

A rectangular piece of cardboard that is 10 inches by 14 inches has squares of length x inches on a side cut from each corner. (Assume that 0 < x < 5.) If the flaps of the figure are folded up, an open box is formed. Represent the volume of this box in the form of a polynomial function V(x).
Answers
This is an aproximation of the described situation. We are taking 4 squares of side lenght x from each corner.
The dashed lines mark up what would be the base of the box. The blue scrabbled areas will be the sides of the box.
Recall that to calculate the volume of the box, we need to multiply the lenghts of each side of the base and then multiply it by the height of the box. So, to calculate the volume we need to determine the lenght of the dashed lined.
Let us calculate the lenght of the black dashed lines. Notice that the horizontal side has a total lenght of 14. So, since we are taking 2 squares of side x, we have that the lenght of the dashed line plus twice the lenght x, we get the total lenght of the side. That is
[tex]\text{Black dashed line + 2x = 14}[/tex]Then the lenght of the black dashed line is 14-2x.
In the same manner, we can calculate the red dashed lines' lenght. It is 10-2x. Now, our box would be
In the picture, the green line represents the height. Comparing the blue and red lines, we have that the lenght of the green line corresponds to the lenght of the side of the square (x).
So now, we know that the volume of the box is
height * lenght of the base * width of the base = (14-2x)*(10-2x) * (x)
which is a polynomial of the variable x.
