Margot draws a shape with one pair of parallel lines that are four centimeter apart she then flips the shape across a horizontal line how many pairs of parallel lines are on the flipped shape?
Answers
Here we have a problem of reflections and of how these reflections affect lines. Here we will find that the reflection does not affect the pair of parallel lines, and in the flipped shape we still have a pair of parallel lines.
We can define two parallel lines as two lines that never meet.
And, for a given point (x, y), the simplest reflection across a horizontal line is the reflection across the x-axis (or the line y = 0) as it transforms the point into:
(x, - y)
And all the reflections across horizontal lines will only affect the y-value of the points.
Now, particularly, we have two vertical and parallel lines.
Notice that a vertical line is defined by its x-value, and the transformation we used does not affect the x-value, so a reflection across a horizontal line will not affect a vertical line.
From this, we can conclude that the reflection across a horizontal line will not affect the pair of vertical parallel lines, so at the end, we still have only one pair of parallel lines.

Step-by-step explanation:

1 - n^3 = -(n -1)(n^2 + n + 1) and

Step-by-step explanation:
As O is the mid point of the circle
Similarly, B also becomes the mid point of the line AC.
So, line OB divides AB and BC equally.
Hence, lines AB = AC, but they are asking to prove congruency of triangles.
So, u have to join OA and OC.
Same way, line OB divides ∠OBA and ∠OBC.
So it is proved that AB = AC
A man is37years old and his child is eight.how many years ago was the product of their ages 96 as in quadratic equation step by step
Answers
Answer:
5 years
Step-by-step explanation:
Let x be the unknown numer of years ago when the product of the man and his child's age was 96.
》 x years ago, the man's age = 37 - x
the child's age = 8 - x
(37 - x)(8 - x) = 96
296 - 37x - 8x + x² = 96
x² - 45x - 296 - 96 = 0
x² - 45x - 200 = 0
x² - 5x - 40x - 200 = 0
x(x - 5) -40(x - 5) = 0
(x - 5)(x - 40) = 0
x = 5 years ago or x = 40 years ago
but x = 40 > son's present age.
Thus, x = 5.
Therefore, 5 years ago the product of the ages of the man and his child was 96.

Answers
Using the information in the exercise to develop the system of equations and using the substitution method, the following answers are found:
The system of the linear equations is P = F + 0.50, 2D = 3F - 0.50, and 2P + F + 3D = 7.75, where P = The price of a box of popcorn, D = The price of a drink, and F = The price of a piece of fruit. By other hand, the price of each item is: Popcorn = $1.50, Drink = $1.25, and Fruit = $1.
Solution of the system of equations by the Substitution Method.
Taking into account the information given in the exercise, we can write the next equations:
P = F + 0.502D = 3F - 0.502P + F + 3D = 7.75Where:
P = The price of a box of popcorn.D = The price of a drink.F = The price of a piece of fruit.Since all equations have the variable F, we are going to use it as a key variable to represent the other variables in terms of F.
In the first equation we should not do anything, since P is in terms of F, in the second case the variable D is also in terms of F, but we need to find the value of just D, by this:
2D = 3F - 0.50D = (3F - 0.50) / 2D = 1.5F - 0.25We proceed to substitute the first and second equations in the third equation:
2P + F + 3D = 7.752 (F + 0.50) + F + 3 (1.5F - 0.25) = 7.75And we solve for the variable F:
2F + 1 + F + 4.5F - 0.75 = 7.757.5F + 0.25 = 7.757.5F = 7.75 - 0.257.5F = 7.5F = 7.5 / 7.5F = 1Now, we can solve for the variable D with the second equation:
2D = 3F - 0.502D = 3 * (1) - 0.502D = 3 - 0.502D = 2.5D = 2.5 / 2D = 1.25Finally, we can solve for the variable P with the first equation:
P = F + 0.50P = 1 + 0.50P = 1.50So, we have the price of each item:
Popcorn = 1.50Drink = 1.25Fruit = 1If you want to see another exercise solved by the substitution method, you can see this link: https://brainly.com/question/22340165?referrer=searchResults
