Luigi incorrectly solved the following equation. Explain the error in Luigi's work.
Complete your work in the space provided or upload an image of your work completed on paper.
Answer:
the error(s) is from the step 2
Step-by-step explanation:
3r - 12 = 2r - 3 +4r
3r - 4r -2r = 12 - 3
-3r = 9
r = 9 : (-3)
r = -3
--------------------------
the error(s) is from the step 2
Which of the following best describes the slope of the line below?
O A. Zero
B. Negative
C. Positive
D Undefined
If you look at the graph, you will realize that it is highest to the left and lowest to the right and that as x increases, the y decreases, and when x decreases, y increases. Thus it has a NEGATIVE slope.

Answer:
I think its -12.9
Step-by-step explanation:
find the value of k so that the two given lines are parallel. -5x+kx=4 2y-9x=11
The value of k so that the two given lines are parallel is; k = 22.5
First, the correct question is;
-5y+ kx = 4 and 2y-9x=11In line segment geometry;
The slopes of two or more parallel lines are equalFirst, we must determine the slope of the lines by rewriting the equations to resemble the equation of a line in the slope-intercept form; y = mx + c
Therefore, we have;
y = (k/5)x - 4/5.................eqn(1)and y = (9/2)x + 11/2....,........eqn(2)Evidently, the slope of the line in equation 2 is; 9/2.
And since the slope of parallel lines are equal;
k/5 = 9/2By cross product;
2k = 45k = 22.5

Answer:
A only
Step-by-step explanation:
I knew a good trick to where if all the digits in your number add up to a multiple of 3, the original number is divisible by 3.
5 + 0 + 9 + 9 + 4 = 27
8 + 8 + 0 + 0 + 7 = 23
4 + 1 + 9 + 5 + 7 = 26
6 + 5 + 8 + 3 + 6 = 28
1 + 9 + 7 + 9 + 9 = 35
1 + 9 + 1 + 2 + 1 = 14
The only number divisible by 3 is 50,994

What is the measure of angle 1? Put the number only.
Answer:
angle 1 = 120 degree
Step-by-step explanation:
75 degree + 45 degree = angle 1 (sum of two opposite interior angles is equal to the exterior angle formed)
120 degree = angle 1
Answer:
120
Step-by-step explanation:
75 + 45 = 120
The triangle adds up to 180.
180 - 120 = 60
Therefore the inside of the triangle is 75, 45, and now 60 which all adds up to 180.
--
Now to find Angle 1.
180 - 60 = 120
With Angle 1 being 120

addison and kelsey are running on a path modeled by x^2+y^2-10x-18y-378=0, where the distance is in meters. what is the maximum distance between the runners at any given time
The maximum distance is the diameter of the circle, which is of 44 units.
The equation of a circle of radius r and center [tex](x_0,y_0)[/tex] is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
The diameter is twice the radius, and is the maximum distance between two points inside a circle.In this problem, the circular path is modeled by:
[tex]x^2 + y^2 - 10x - 18y - 378 = 0[/tex]
We complete the squares to place it in the standard format, thus:
[tex]x^2 - 10x + y^2 - 18y = 378[/tex]
[tex](x - 5)^2 + (y - 9)^2 = 378 + 25 + 81[/tex]
[tex](x - 5)^2 + (y - 9)^2 = 484[/tex]
Thus, the radius is:
[tex]r^2 = 484 \rightarrow r = \sqrt{484} = 22[/tex]
Then, the diameter is:
[tex]d = 2r = 2(22) = 44[/tex]
The maximum distance is the diameter of the circle, which is of 44 units.

A particular plant root grows 2.5 inches per month. How many centimeters is the plant root growing per month? (1 inch = 2.54 centimeters).
Answer:
The plant root is growing 6.35 cm per month.
Step-by-step explanation:
This is a conversion problem. You are converting 2.5 inches to centimeters.
2. 5 inches * 2.54 cm/1 inch
inches cancels out and now you are left with multiplying 2.5 and 2.54.
2.5 * 2.54 cm = 6.35 cm

18. A shipwreck is 300 meters away from a diving station. An undersea
explorer travels away from the station at a speed of 2 meters per second.
The explorer is x meters away from the station and will reach the
shipwreck in 100 seconds. What is the value of x?
Answer:
me too jaja
Step-by-step explanation:
The value of x is 100 meters if the shipwreck is 300 meters away from a diving station. An undersea explorer travels away from the station at a speed of 2 meters per second.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
It is given that:
A shipwreck is 300 meters away from a diving station.
An undersea explorer travels away from the station at a speed of 2 meters per second.
The explorer is x meters away from the station and will reach the
shipwreck in 100 seconds.
As we know,
Distance = time×speed
Distance = 100×2
Distance = 200 meterse
x = 300 - 200
x = 100 meters
Thus, the value of x is 100 meters if the shipwreck is 300 meters away from a diving station. An undersea explorer travels away from the station at a speed of 2 meters per second.

The ordinate of a point is twice its abscissa . If its distance from the point (4,3) is √10 units ,then the coordinates of the point are ?
Answer:
(1 , 2) and (3 , 6)
Step-by-step explanation:
the point P : (x , y) -> (x , 2x) ... ordinate of P point is twice its abscissa, y = 2x
√10 = √(x-4)² + (2x-3)²
5x² - 20x + 25 = 10
x² - 4x + 3 = 0
(x-1)(x-3) = 0
x = 1 or x = 3
y = 2 or y = 6
