Given:
The pair of end points: (3,-8) and (3,-1).
To find:
Whether the given pair of endpoints lies on the same horizontal or vertical line.
Solution:
If the x-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same vertical.
If the y-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same horizontal.
The given endpoints are (3,-8) and (3,-1).
From the given endpoints, it is clear that the x-coordinates of the endpoints are same. So, the given endpoints lies on the same vertical line.
The length of the line segment that joins the pair of points is
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]D=\sqrt{(3-3)^2+(-1-(-8))^2}[/tex]
[tex]D=\sqrt{(0)^2+(-1+8)^2}[/tex]
[tex]D=\sqrt{(7)^2}[/tex]
[tex]D=7[/tex]
Therefore, the given endpoints lies on the same vertical line and the length of the line segment is 7 units.

The equation 201.50=f+6.50(21) represents the cost of printing the shirts at a second printing company. Find the solution to the equation. The solution is . State what the solution represents in this situation.
Answer:
f = 65
Setup cost = 65
Step-by-step explanation:
Given the equation : 201.50=f+6.50(21)
Solving for f:
201.50 = f + 136.50
201.50 - 136.50 = f
f = 65
The equation above is written in the form a slope intercept function where,, 6.50 is the gradient and X equals the number of shirts, The total cost of printing is 201.50
f is the intercept and represents the initial fee or setup cost. Hence, the setup. Cost = 65

2. Determine the slope of the line that passes through
the points (-1, -3) and (0, 6).
Answer:
9
Step-by-step explanation:
use the formula m = y2- y1 / x2 - x1
Answer:
Step-by-step explanation:
The slope of a line can be found using any two points of a line and the slope, m, is defined as
m=(y2-y1)/(x2-x1), we have points (-1,-3) and (0,6) so
m=(6-(-3))/(0-(-1))
m=9/1
m=9

martha can paint a room in 8 hours. jamie can paint the same room in 4 hours. how long to the nearest tenth of an hour will it take them to paint the room together
Answer:
in 1 hr martha finishes 1/8th of the room
in 1hr jaime finishes 1/4th of the room
combined in 1hr they can finish (1/8 + 1/4) = 3/8th of the room.
for painting the whole room both of them together it takes the 8/3 hrs = 2.67hr
How does labeling the diagram help us show that we can use right triangle congruency (SAS in this case)?
Answer:
Step-by-step explanation:
S A S congruence rule: Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of other triangle.
If two triangles are congruent by SAS, and the angle is 90, then by CPCT{corresponding part of congruent triangle) the hypotenuse of the two triangles will be congruent.
Now, as hypotenuse and one leg are congruent in both triangles, we can apply RHS congruent

Write the equation in slope-intercept form: 5x - 2y = 12
Answer:
Step-by-step explanation:
Solving
5x + -2y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
5x + -2y + 2y = 12 + 2y
Combine like terms: -2y + 2y = 0
5x + 0 = 12 + 2y
5x = 12 + 2y
Divide each side by '5'.
x = 2.4 + 0.4y
Simplifying
x = 2.4 + 0.4y

The area of a rectangle with a length of 12m and a width if 4m is ________square meters.
Answer:
48 square meters
Step-by-step explanation:
cause if u 4m x 12m =48
Answer:
48 square meters
Step-by-step explanation:
The equation used to solve this is a= wl (area equals length times width)
Therefore, all you have to do is multiply 12 and 4 to get the area of the rectangle.
12 times 4= 48

find the lateral area of this cone
Answer:
lateral area = 180π in²
Step-by-step explanation:
The lateral area is the surface of the cone only.
perimeter of base = 12 x 2 = 24π in
Surface Area = 1/2 perimeter x slant height
SA = 1/2 x 24π x 15 = 180π in²
Solve the inequality: 5x + 7 < -23
Step-by-step explanation:
Given
5x + 7 < - 23
Subtracting 7 from both sides
5x + 7 - 7 < - 23 - 7
5x < - 30
Dividing both sides by 5
5x / 5 < - 30 / 5
x < - 6

5x=14
Divide both sides by 5
x =14/5

Step-by-step explanation:
Graph and see which one matches
The equation best represents circle is (x-2)^2 + (y-1)^2 = 12^2, the correct option is B
What is the equation of the circle with radius r units, centered at (x,y) ?If a circle O has radius of r units length and that it has got its center positioned at (h, k) point of the coordinate plane, then, its equation is given as:
(x-h)^2 + (y-k)^2 = r^2
Given;
The graph of circle
Now,
h=-2
k=-1
(x-h)^2 + (y-k)^2 = r^2
Substituting the values
(x-2)^2 + (y-1)^2 = 12^2
Therefore, the equation of circle will be (x-2)^2 + (y-1)^2 = 12^2.

A rectangle has area x3 + 3x2 - 18x in.2 and width x + 6 in. What is the length in inches?
Answer:
HOPE THIS HELPS
Step-by-step explanation:
The area = length * Width.
We know the width = X+6 inches and Area = x^3+3x^2–18x.
This problem can be solved just by dividing the area by width and we get a quotient as X^2–3x.
So the length is x^2–3x inches.
The length of the rectangle is [tex]\rm x(x-3)[/tex].
Given
The area of the rectangle = [tex]\rm x^3+3x^2-18x[/tex] square inches
The width of the rectangle = x + 6 inches
Area of the rectangleThe area of the rectangle is equal to the product of length and width of the rectangle.
Let the length of the rectangle be L.
The area of the rectangle is given by;
[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\[/tex]
Substitute all the values in the formula;
[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\\rm x^3+3x^2-18x= L \times (x+6)\\\\L=\dfrac{ x^3+3x^2-18x}{x+6}\\\\L = \dfrac{ x(x+6)(x-3)}{x+6}\\\\ L = x (x-3)[/tex]
Hence, the length of the rectangle is [tex]\rm x(x-3)[/tex].
