Triangle XYZ is shown on the coordinate plane below:
Triangle XYZ on the coordinate plane with ordered pairs at X 3, negative 1, at Y 4, negative 4, at Z 1, negative 2
If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?
Answers
(3, -1)
(4, -4)
(1, -2)
The triangle created is the first file attached.
When reflected off of the line y = 1, it is one higher y than reflecting off the y axis. So, the coordinates are (1,-4) (3, 3) (4, 6)
The ordered pair of [tex]X'[/tex] is [tex](3,3)[/tex]
Explanation
According to the below diagram, the co ordinates of [tex]\triangle XYZ[/tex] are: [tex]X(3, -1), Y(4,-4)[/tex] and [tex]Z(1,-2)[/tex]
The triangle [tex]XYZ[/tex] is reflected across the line [tex]y=1[/tex] to create triangle [tex]X'Y'Z'[/tex]
Distance of the point [tex]X[/tex] from the line [tex]y=1[/tex] is 2 units.
So, the point [tex]X'[/tex] will be also 2 units above the line [tex]y=1[/tex]. As the triangle is reflected across a horizontal line, so the [tex]x[/tex] co-ordinate of the point will remain same.
[tex]y[/tex] co-ordinate of the point [tex]X'[/tex] will be: [tex]y=1+2 =3[/tex]
So, the ordered pair of [tex]X'[/tex] is [tex](3,3)[/tex]

A master electrician earns $62 per hour. His apprentice earns $40 per hour. The master electrician works 3 hours more than the apprentice. If together they are paid $492, how much does the master electrician earn?
A) $292
B) $312
C) $332
D) $372
Answers
The master electrician earns $62 per hour, which means that he earns 62x.
His apprentice earns $40 per hour, which means that he earns 40y.
Together they are paid $492, so we can get the equation:
62x + 40y = 492.
We know that the electrician worked 3 hours more than his apprentice. So he worked x = y + 3 hours. Now let's replace x by its new value in the previous equation.
62x + 40y = 492
62(y+3) + 40y = 492
62y + 186 + 40y = 492
Now we need to put variables apart and numbers apart, so we subtract 186 from both sides of the equation:
62y + 40y + 186 - 186 = 492 - 186
102y = 306
Now we divide both sides by 102
(102y)/102 = 306/102
y = 3
So the apprentice worked 3 hours.
As we already mentioned, the electrician worked 3 hours more than his apprentice.
So he worked x = y + 3 = 3+3 = 6 hours.
The master electrician earns $62 per hour. Since he worked 6 hours, he earns 62 * 6 = 372 dollars.
So the master electrician earns $372 (Option D)

You have a rectangular vegetable garden in your backyard that measures 15 feet by 10 feet. You want to double the area of the garden by adding the same distance x to the length and width of the garden. Find the value of x and the new dimensions of the garden.
Answers
To double the area of the rectangular vegetable garden, we need to add the same distance, x, to the length and width. The value of x is 10 feet, and the new dimensions of the garden are 25 feet by 20 feet.
Explanation:To double the area of the garden, we need to add the same distance, x, to both the length and width of the garden. The original dimensions of the garden are 15 feet by 10 feet, with an area of 150 square feet. To double the area, we set up the equation 2(15+x)(10+x) = 2(15)(10). Solving this equation gives us the value of x and the new dimensions of the garden.
Expanding the equation, we have 30x + x² + 300 = 300. This simplifies to x² + 30x - 300 = 0. Factoring this quadratic equation, we get (x - 10)(x + 30) = 0. So x = -30 or x = 10. We discard the negative value since distance cannot be negative, so x = 10 feet.
The new dimensions of the garden are 15+10 = 25 feet and 10+10 = 20 feet.

A rectangle has one side on the xx-axis and two vertices on the curve y=74+x2. y=74+x2. find the vertices of the rectangle with maximum area.
Answers
We find the vertices of the rectangle with maximum area as follows:
Because of the symmetry of the given curve, the base of the retangle is 2x and the height of the rectangle is y.
Thus, the area of the required rectangle is 2xy where [tex]y= \frac{7}{4+x^2} [/tex]
Thus, [tex]Area=\frac{14x}{4+x^2}[/tex]
For maximum area, we find value of x for which the derivative of the function for the area is equal to zero.
The derivative of the function for the area is given by:
[tex](Area)'= \frac{14(4-x^2)}{(4+x^2)^2} =0 \\ \\ \Rightarrow4-x^2=0 \\ \\ \Rightarrow x^2=4 \\ \\ \Rightarrow x=\sqrt{4}=2[/tex]
Thus, the area is maximum when x = -2 and x = 2
When x = -2,
[tex]y= \frac{7}{4+(-2)^2}= \frac{7}{4+4} = \frac{7}{8} [/tex]
Similarly, when x = 2,
[tex]y= \frac{7}{4+(2)^2}= \frac{7}{4+4} = \frac{7}{8} [/tex]
Therefore, the required vertices are: [tex](-2,0),\ \left(-2, \frac{7}{8} \right), \ \left(2, \frac{7}{8}\right), \ (2, 0)[/tex]
The rectangle with maximum area does not exist as the curve y = 74 + x^2 does not intersect the x-axis.
Explanation:To find the vertices of the rectangle with maximum area, we need to find the points of intersection between the curve y = 74 + x^2 and the x-axis.
Setting y = 0, we can solve the equation 74 + x^2 = 0 to find the x-coordinates of the vertices.
Since the curve is a parabola facing upwards, there are no points of intersection with the x-axis.
Therefore, the rectangle does not exist.

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −7 0 −1 1 5 g(x) g(x) = 5x − 4 Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) Part B: Which function has a greater y-intercept? Justify your answer. (4 points)
Answers
Rewriting the table for f(x):
x -1 0 1
f(x) -7 -1 5
Notice that for every increase of one unit in 'x', there are an increase 6 units on f(x). Hence, the gradient of the slope of f(x) is 6.
g(x) = 5x - 4 ⇒ This function follows the general form of the straight line equation, y = mx + c, where 'm' is the gradient and 'c' is the y-intercept.
Hence, the gradient of the slope of g(x) is 5.
The slope of f(x) is steeper than the slope of g(x).
---------------------------------------------------------------------------------------------------------------
Question B:
The y-intercept is the value of y where a straight line crosses the y-axis (or when x is zero).
From the table of f(x), the y-intercept is -1 (this is the value of 'y' when 'x' is zero)
From the given function g(x) = 5x - 4, the y-intercept is -4.
f(x) has a greater y-intercept.

Anna has 10 to the 2nd power quarters. Jazmin has 10 to the second power dimes Who has more money, Anna or Jasmine? How much more? Explain
Answers
A quarter is 25 cents, while a dime is only 10 cents. Since they both have the same amounts of coins, the one with 100 quarters has more money, so Anna has more money than Jasmine.
Now, we need to figure put by how much! 100 quarters is one hundred 25 cent coins. 100*25 = 2500. That is 25 dollars. Whereas, Jasmine has one hundred times 10 cents, which is 1000 cents. This is 10 dollars.
So, Anna has 15 more dollars than Jasmine.
This question is based on the concept of logical reasoning.Therefore,they both have the same amounts of coins, the one with 100 quarters has more money.Thus, Anna has more money than Jasmine.
Given:
Anna has 10 to the 2nd power quarters. Jazmin has 10 to the second power dimes.
We need to calculate the who has more money, Anna or Jasmine.
According to the question,
Anna has 10 to the 2nd power quarters.
In mathematically expressed as,
[tex]\bold{10^2 = 100}[/tex] quarters
Now, Jazmin has 10 to the second power dimes.
In mathematically expressed as,
[tex]\bold{10^2 = 100}[/tex] dimes
So,they both have 100 coins. But, we know that quarter is 25 cents, while a dime is only 10 cents.
Anna has 100 quarters = [tex]\bold{100 \times 25 = 2500}[/tex]. That is 25 dollars.
Jasmine has 100 dimes = [tex]\bold{100 \times 10 = 1000}[/tex]. This is 10 dollars.
Therefore,they both have the same amounts of coins, the one with 100 quarters has more money.Thus, Anna has more money than Jasmine.
