"Write two equations: one parallel, one perpendicular to (5,-2) y= 1/5x-3
Write in the form y=mx±b,y=mx±b (first the parallel, then the perpendicular)"
Answers
Answer:
For parallel:
gradient is 1/5
\(y = mx + c\)
consider (5, -2):
\( - 2 = ( \frac{1}{5} \times 5) + c \\ - 2 = 1 + c \\ c = - 3\)
\({ \boxed{ \bf{equation : y = \frac{1}{5}x - 3 }}}\)
For perpendicular:
gradient, m1:
\(m _{1} \times m_{2} = - 1 \\ m _{1} \times \frac{1}{5} = - 1 \\ \\ m _{1} = - 5\)
gradient = -5
\(y = mx + c \\ - 2 = (5 \times - 5) + c \\ - 2 = - 25 + c \\ c = 23\)
\({ \boxed{ \bf{equation :y = - 5x + 23 }}}\)
Answer:
Parallel: \(y=\displaystyle \frac{1}{5}x-3\)
Perpendicular: \(y=-5x+23\)
Step-by-step explanation:
Hi there!
What we must know:
Slope intercept form: \(y=mx+b\) where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines always have the same slopePerpendicular lines always have slopes that are negative reciprocals (ex. 2 and -1/2, -6/7 and 7/6)Finding the Parallel Line
\(y=\displaystyle \frac{1}{5} x-3\)
Given this equation, we can identify that its slope (m) is \(\displaystyle \frac{1}{5}\). Because parallel lines always have the same slope, the slope of the line we're currently solving for would be \(\displaystyle \frac{1}{5}\) as well. Plug this into \(y=mx+b\):
\(y=\displaystyle \frac{1}{5}x+b\)
Now, to find the y-intercept, plug in the given point (5,-2) and solve for b:
\(-2=\displaystyle \frac{1}{5}(5)+b\\\\-2=1+b\\-2-1=b\\-3=b\)
Therefore, the y-intercept is -3. Plug this back into \(y=\displaystyle \frac{1}{5}x+b\):
\(y=\displaystyle \frac{1}{5}x+(-3)\\\\y=\displaystyle \frac{1}{5}x-3\)
Our final equation is \(y=\displaystyle \frac{1}{5}x-3\).
Finding the Perpendicular Line
\(y=\displaystyle \frac{1}{5} x-3\)
Again, the slope of this line is \(\displaystyle \frac{1}{5}\). The slopes of perpendicular lines are negative reciprocals, so the slope of the line we're solving for would be -5. Plug this into \(y=mx+b\):
\(y=-5x+b\)
To find the y-intercept, plug in the point (5,-2) and solve for b:
\(-2=-5(5)+b\\-2=-25+b\\-2+25=b\\23=b\)
Therefore, the y-intercept is 23. Plug this back into \(y=-5x+b\):
\(y=-5x+23\)
Our final equation is \(y=-5x+23\).
I hope this helps!

Certainly! The problem can be solved using the Pythagorean theorem,
which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In this case, the ladder acts as the hypotenuse, and we need to find the length of the vertical side (height) it reaches up the wall.
The ladder forms the hypotenuse, and its length is given as 12 meters. The distance from the foot of the ladder to the base of the wall represents one side of the triangle, which is 4.5 meters.
By substituting the given values into the Pythagorean theorem equation: (12m)^2 = h^2 + (4.5m)^2, we can solve for the unknown height 'h'.
Squaring 12m gives us 144m^2, and squaring 4.5m yields 20.25m^2. By subtracting 20.25m^2 from both sides of the equation, we isolate 'h^2'.
We then take the square root of both sides to find 'h'. The square root of 123.75m^2 is approximately 11.12m.
Therefore, the ladder reaches a height of approximately 11.12 meters up the wall.

Find the vertex of the graphed function. f(x) = [x - 4] + 3
Answers
The vertex of the graphed function f(x) = [x - 4] + 3 is (4, 3).
The function f(x) = [x - 4] + 3 is in the form of an absolute value function, where the expression inside the absolute value brackets represents the input value shifted horizontally by 4 units to the right.
The constant term of 3 represents a vertical shift upwards by 3 units.
To find the vertex of this function, we need to determine the x-coordinate that corresponds to the minimum value of the absolute value function.
In this case, since the absolute value function is within brackets and not being multiplied or divided by a coefficient, the minimum value occurs at the point where the expression inside the brackets equals zero.
Therefore, setting x - 4 = 0, we find x = 4.
Substituting this x-value into the function, we find f(4) = [4 - 4] + 3 = 3. So the vertex of the graphed function is located at the point (4, 3), where x = 4 and y = 3. This means that the graph is shifted 4 units to the right and 3 units upward from the origin.

Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 5 hours. Together they charged a total of $1125. What was the rate charged per hour by each mechanic if the sum of the two rates was $140 per hour?
Answers
Answer:
The first mechanic charged $ 85 an hour, and the second mechanic charged $ 55 an hour.
Step-by-step explanation:
Given that two mechanics worked on a car, and the first mechanic worked for 10 hours, and the second mechanic worked for 5 hours, and together they charged a total of $ 1125, to determine what was the rate charged per hour by each mechanic if the sum of the two rates was $ 140 per hour, the following calculation must be performed:
1125/15 = X
75 = X
80 x 10 + 60 x 5 = 800 + 300 = 1100
85 x 10 + 55 x 5 = 850 + 275 = 1125
Therefore, the first mechanic charged $ 85 an hour, and the second mechanic charged $ 55 an hour.

Enseñanza Básica is the term used to describe the first level of education in the Chilean education system, which includes the first to eighth grades. A teacher of Enseñanza Básica asked his students to choose three-digit mixed numbers that can be formed.
A mixed number is a number that has both a whole number and a fraction component. To form three-digit mixed numbers, we need to have a whole number that is less than 100 and a proper fraction that has a denominator less than or equal to 99. Here are some examples:123 4/567 2/8109 1/2382 3/47There are a total of 900 three-digit numbers that can be formed using digits 1 to 9 without repetition. To find the number of three-digit mixed numbers that can be formed, we need to count the number of ways we can choose a proper fraction with a denominator less than or equal to 99. There are 99 possible denominators, and for each denominator, there are 98 possible numerators (excluding 0 and the denominator itself). Therefore, the total number of three-digit mixed numbers that can be formed is:900 x 99 x 98 = 8,334,600There are 8,334,600 three-digit mixed numbers that can be formed using digits 1 to 9 without repetition.For such more question on fraction

On the coordinate plane, point K is located at (3, -2) and point L is located at (x, 6). The
distance between points K and L is 10 units.
Graph one possible point L on the coordinate plane.
Answers
All of the points along the y-axis are located in the region of the coordinate plane that is equally distant from the coordinates a(-3 2) and b(3, 2).
Find the coordinate plane by what method?The x-axis, a horizontal number line, and the y-axis, a vertical number line, cross to create a coordinate plane. The coordinate plane's origin is where the two axes—plural for "axes"—vertically intersect.
What is an illustration of a coordinate plane?Each point on a coordinate plane will have an x coordinate and a y coordinate, which are stated as (x, y). For instance, the coordinate (3,2) has a y-coordinate of 2, an x-coordinate of 3, and a coordinate in between.
Here,
Given: K(3, -2) and (x, 6).
Thus ,distance between points K and L is 10 units.
Thus,
=> 10 = \(\sqrt{(3-x)^{2}-(-2-6)^{2} }\)
=> 10 = \(\sqrt{9+x^{2} -6x+64\\\)
=> 100 = 73 +\(x^{2}\) -6x
=> 27 =\(x^{2}\) -6x
=>\(x^{2}\)-6x-27=0
=>x(x-9)+3(x-9)
