Two perpendicular lines have opposite y-intercepts. The equation of one of these lines is y = mx + b. Express the x-coordinate of the intersection point of the lines in terms of m and b.
The x-coordinate of the intersection point of two perpendicular lines, one with equation y = mx + b and the other with equation y = -x/m - b, is given by x = 2b/(m + 1/m).
Explanation:Given two perpendicular lines, one has the equation y = mx + b. The y-intercept of this line is b, and the slope is m. The equation of the second line, which is perpendicular to the first, will have a negative reciprocal slope, -1/m, and for opposite y-intercepts, we'll assume its y-intercept to be -b. Thus the equation of the second line is y = -x/m - b.
For the intersection point, equal the y-values of the two equations: mx + b = -x/m - b. Simplify to obtain the x-coordinate of the intersection point:
mx + x/m = 2b or x(m + 1/m) = 2b. Therefore, the x-coordinate of the intersection point is x = 2b/(m + 1/m).

To find the x-coordinate of the intersection point of two perpendicular lines with opposite y-intercepts, set the equations of the lines equal to each other and solve for x.
Explanation:To find the x-coordinate of the intersection point of two perpendicular lines with opposite y-intercepts, we need to find the equations of both lines. Let's assume the equation of one line is y = mx + b. Since the lines are perpendicular, the slope of the other line will be the negative reciprocal of m. Let's call the slope of the other line n. Therefore, the equation of the other line will be y = -nx + c, where c is the y-intercept of the second line. To find the x-coordinate of the intersection point, we can set the two equations equal to each other and solve for x:
mx + b = -nx + c
x(m + n) = c - b
x = (c - b)/(m + n)

Lines k and n are perpendicular. If the slope of line k is -6, what is the slope of line n?
A. -6
B.-1/6
C.6
D.1/6
Lines k and n are perpendicular
The slope of line k is -6
Fact: The product of slopes of two perpendicular lines = -1
So the slope of line n = -1 ÷ -6 = 1/6
The correct choice is 'D.'
If lines k and n are Slopes of Perpendicular Lines k is -6, then the slope of the perpendicular line n is 1/6.
In the study of Mathematics, especially when dealing with Geometry and Algebra, understanding the relationship between lines can be critical.
This particular question asks about perpendicular lines and their slopes. If lines k and n are perpendicular, knowing the slope of one can help deduce the slope of the other.
As per the properties of perpendicular lines, the product of their slopes is -1.
In the case where the slope of line k is -6, the slope of the perpendicular line n would be the Positive reciprocal, which is simply flipping the fraction and changing the sign.
Hence, the slope of line n would be 1/6.
So, ultimately the answer is Option d: 1/6, which is the slope of line n that is perpendicular to line k with a slope of -6.

Describe the end behavior of the following function:
Answer:
The correct answer is that the function starts high and ends low.
Step-by-step explanation:
First we need to check for the highest power in a term. Since it is 5, which is an odd number, we know that they start and end in different places.
Next, we determine where it finishes based on the coefficient of that term, which is -1. Since it is negative, we know it finishes down. Since they are different, this means it starts up
Answer:
A ) The graph of the function start high and ends low .
Step-by-step explanation:
Given : f(x) = [tex]-x^{5} +x^{2} -x[/tex].

Use the figure to complete the transformations.
1. Reflect the triangle across the y-axis.
2. Reflect the image across the x-axis.
The final image is the same as what single transformation?
a reflection across the y-axis
a 180° rotation about the origin
a clockwise rotation 90° about the origin
If you actually do what the problem statement tells you to do, the answer falls into your lap.
The attachment shows the triangle reflected across the y-axis (blue), then across the x-axis (red). The red triangle is clearly equivalent to the original being rotated 180° about the origin.
The appropriate choice is ...
... a 180° rotation about the origin
_____
Algebraically, reflection across the y-axis negates the x-coordinate:
... (x, y) ⇒ (-x, y)
and reflection across the x-axis negates the y-coordinate:
... (x, y) ⇒ (x, -y)
Then, reflection across first one axis then the other will result in both coordinates being negated:
... (x, y) ⇒ (-x, -y)
This is precisely what happens when a figure is rotated 180° about the origin.
Answer:
A 180 rotation about the origin

Write the function rule for the function shown below reflected in the given axis. f(x)=5x;x-axis
Hello!
Given the function, f(x) = 5x, find the equation where the function f, is reflected over the x-axis.
There are two types of reflections. One reflection is over the x-axis (the most common) and over the y-axis.
Say for example, we are given the point (x, y), and we want to reflect it over the x-axis. If the point (x, y) is reflected over the x-axis, then the point is (x, -y). Why? It's because y-values above the x-axis are POSITIVE while x-values below are NEGATIVE.
So, an equation to show this is: y = -f(x).
To find it, we multiply the entire function, which is f(x), by a negative. Since f(x) = 5x, the transformed function is f(x) = -5x.
Therefore, the function rule for the function shown is -f(x).
The function rule for the function f(x) = 5x reflected over the x-axis is -f(x) = -5x. This is due to the reversal of the y-values when reflecting a function over the x-axis.
Explanation:In Mathematics, when we reflect a function over the x-axis, it simply means reversing the signs of the y-values. For this given function f(x) = 5x, its reflection would get the y-values inverted, which would convert the positive to negative (or vice versa). Taking this into account, the function reflecting in the x-axis would be -f(x) = -5x.

Step-by-step explanation:
The number of servings is found by dividing the quantity available by the size of a serving. The quantity of punch is the sum of the quantities of the juices that go into the punch. The serving size of 3/4 cup is the same as 6 ounces, since a cup is 8 ounces. (3/4 × 8 oz = 6 oz)
The quantity available is (64 oz + 28 oz + 76 oz). The serving size is 6 oz. Since the units of numerator and denominator are the same, they cancel, leaving ...
... number of servings = (quantity available)/(serving size)
... = (64 +28 +76)/6 . . . . as shown in the problem statement
_____
It might not be obvious that the above ratio gives the number of servings. However, if you look at the real units, you see how it happens.
[tex]\dfrac{oz}{(\frac{oz}{serving})}= oz\dfrac{serving}{oz}=\dfrac{oz}{oz}serving=serving[/tex]

the point was reflected over the x- axis
note that for reflection in the x- axis
a point (x, y ) → (x, - y )
the x-coordinate remains unchanged while the y- coordinate of the image is the negative of the original y- coordinate
Answer:
Option B and C are correct.
Step-by-step explanation:
It is given that A point located at (1, 6) undergoes a transformation. Its image is at (1, -6).
[tex]P(1,6)\rightarrow P'(1,-6)[/tex]
If the point was reflected over the y-axis, then
[tex]P(x,y)\rightarrow P'(-x,y)[/tex]
[tex]P(1,6)\rightarrow P'(-1,6)\neq P'(1,-6)[/tex]
If the point was translated down 12 units, then
[tex]P(x,y)\rightarrow P'(x,y-12)[/tex]
[tex]P(1,6)\rightarrow P'(1,6-12)=P'(1,-6)[/tex]
If he point was reflected over the x-axis, then
[tex]P(x,y)\rightarrow P'(x,-y)[/tex]
[tex]P(1,6)\rightarrow P'(1,-6)[/tex]
If he point was translated up 12 units, then
[tex]P(x,y)\rightarrow P'(x,y-+12)[/tex]
[tex]P(1,6)\rightarrow P'(1,6+12)=P'(1,18)\neq P'(1,-6)[/tex]

In number theory, two integers a and b are said to be relatively prime, mutually prime, or coprime if the only positive integer that divides both of them is _____. That is, the only common positive factor of the two numbers is _____. This is equivalent to their greatest common divisor being _____. What number fills in the blanks?
ANSWER
The number that fills in the blanks is 1
EXPLANATION
Two numbers are relatively prime if they have no common factor greater than 1.
For exam 12 and 17 have no common factor greater than 1.
This is equivalent to saying that the greatest common divisor (GCD) of the two numbers is 1.
[tex]gcd(12,17)=1[/tex]
This means that [tex]12[/tex] and [tex]17[/tex] are relatively prime.
But

Jake and erica were solving a system of equations. They both noticed that the two lines had the same slope. Jake said that because each line in the system had the same slope, the two lines had to be the same, which meant there were infinitely as many solutions to the solutions to the system. Erica disagreed, and said they ahould also look at the y-intercepts before determining how many solutions there were. Who is correct?
Answer:
Erica
Step-by-step explanation:
Two lines with the same (defined) slope will only have infinite solutions if their y-intercepts are the same. Otherwise, the number of solutions (points on both lines) is zero.
Since the 2 lines have the same slope, then the lines are parallel and never intersect. Thus there is no solution to the system of equations

what is the equation of a line, in point-slope form, that passes through (5, -3) and has a slope of 2/3? please help me
y + 3 = [tex]\frac{2}{3}[/tex] (x - 5)
the equation of a line in point- slope form is
y - b = m ( x - a )
where m is the slope and (a, b) a point on the line
here m =[tex]\frac{2}{3}[/tex] and (a,b) = (5 , - 3 )
y + 3 = [tex]\frac{2}{3}[/tex] (x - 5 ) ← in point-slope form
The equation of the line that passes through the point (5, -3) and has a slope of 2/3 is y = 2/3x - 19/3, using the point-slope form for the equation of a line.
Explanation:
The line that you're looking for can be represented using the point-slope form of a linear equation. This form is written as y - y1 = m(x - x1), where (x1, y1) are the coordinates of a point on the line and 'm' is the slope of the line. For a line that passes through the point (5, -3) and has a slope of 2/3, you replace x1 with 5, y1 with -3, and m with 2/3. So, the equation of the line becomes y - (-3) = 2/3(x - 5), which simplifies to y + 3 = 2/3x - 10/3. Further simplifying, we get y = 2/3x - 10/3 - 3, or y = 2/3x - 19/3.
