ForAB¯¯¯¯¯¯¯¯ A B ¯ , point A has coordinates (3, -5) and point B has coordinates (-1, 9). What are the coordinates of the midpoint of AB¯¯¯¯¯¯¯¯ A B ¯ ? (2, 7) (2, 7) (-1, 4) (-1, 4) (2, 4) (2, 4) (1, 2)
Given:
Two points are A(3,-5) and B(-1,9).
To find:
The midpoint of AB.
Solution:
Formula for midpoint is
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using this formula, the midpoint of AB is
[tex]Midpoint=\left(\dfrac{(3)+(-1)}{2},\dfrac{(-5)+(9)}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{3-1}{2},\dfrac{-5+9}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{2}{2},\dfrac{4}{2}\right)[/tex]
[tex]Midpoint=\left(1,2\right)[/tex]
Therefore, the midpoint of AB is (1,2). Hence, the correct option is D.

Step-by-step explanation:
Pedals of Petals, a bike manufacturer that makes flower-themed bikes, has a fixed cost of $100,000 due to the equipment necessary to make the bicycles. Additionally, each bike costs $100 in labor and materials to make. If each bike sells for $300, how many bikes must be sold in order for the company to break even?
Answer:
Break-even point in units= 500
Step-by-step explanation:
Giving the following information:
Fixed costs= $100,000
Unitary variable cost= $100
Selling price per unit= $300
To calculate the break-even point in units, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 100,000 / (300 - 100)
Break-even point in units= 500

Answer:
the answer is angle y = 54. ........
Answer:
y = 54
Step-by-step explanation:
Two of the sides are congruent, so the angles that are facing the two sides are also congruent, so:
3(x + 7) = 63
3x + 21 = 63
3x = 42
x = 14
A triangle equals 180 degrees, and input 14 into the equation, so:
3(14 + 7) + 63 + y = 180
3(21) + 63 + y = 180
63 + 63 + y = 180
126 + y = 180
y = 54

Answer:
m1 =131 degrees
m2=49 degrees
Step-by-step explanation:
Alternate interior angles are always congruent, so they will be equal to each other, so m1=131 degrees.
Straight angles always add up to 180 degrees, so 180-131=49, so m2=49 degrees

Jame has six stamps in his stamp collection Roy has 12 stamps on his collection Jame adds two stamps to the collection after James these stamps what is the ratio of stamps and James collection to the stamps and Roy's collection
Given :
Jame has six stamps in his stamp collection Roy has 12 stamps on his collection Jame adds two stamps to the collection.
To Find :
The ratio of stamps of James's and Roy's collection.
Solution :
Number of stamps in Jame's collection, n = 6 + 2 = 8.
Let, ratio of their stamp is R.
[tex]R = \dfrac{\text{Number of stamps James have}}{\text{Number of stamps Roy have}}\\\\R = \dfrac{8}{12}\\\\R = \dfrac{2}{3}[/tex]
Therefore, the ratio of their stamps is 2 : 3 .

Answer:
The Pythagorean Theorem can be used to find the length of the legs and hypotenuse of a triangle. While the distance of a vertical or horizontal line can be counted easily, a diagonal line cannot be determined the same way. A diagonal line, such as the line between the two points shown on the graph, is the hypotenuse of an imaginary right triangle. If you draw the legs of the triangle by drawing straight lines through the points on the graph until the lines meet at a point, you can count the distance of the legs and plug those values into the Pythagorean Theorem.
Step-by-step explanation:
In this case, the meeting point of straight lines drawn through the points is
(-3, -4)
and the distances of the legs of the right triangle are 8 and 6. The theorem is
a² + b² = c²
so 8² + 6² = c² to 64 + 36 = c² to 100 = c² and [tex]\sqrt 100 = \sqrt c^{2}[/tex]
so 10 = c
The distance of the line (hypotenuse) is 10.

Write y= -1(x-4.5)^2 + 15.25 in standered form
Given:
The equation is
[tex]y=-1(x-4.5)^2+15.25[/tex]
To find:
The standard form of the given equation.
Solution:
We have,
[tex]y=-1(x-4.5)^2+15.25[/tex]
It is a quadratic equation.
The standard form of a quadratic equation is [tex]y=ax^2+bx+c[/tex]. So, we need to write the given equation in this form.
[tex]y=-(x-4.5)^2+15.25[/tex]
[tex]y=-[x^2-2(x)(4.5)+(-4.5)^2]+15.25[/tex] [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]
[tex]y=-[x^2-9x+20.25]+15.25[/tex]
[tex]y=-x^2+9x-20.25+15.25[/tex]
[tex]y=-x^2+9x-5[/tex]
Therefore, the required equation in standard form is [tex]y=-x^2+9x-5[/tex].

What is the slope of the line and y intercept PLEASE HELP
Answer:
c. slope: -3/2, y-intercept: 1/2
Step-by-step explanation:
First, let's find out the y-intercept. The y-intercept is where the line crosses the y-axis (the vertical line). In this question, the line crosses the y-axis at 1/2, so that is the y-intercept.
Now, we'll find the slope. The first thing we can do is look for two simple points on the graph. The points I'm going to use are (3, -4) and (1, -1). Slope is written rise over run. If you look at the point (3, -4) and rise (go up/down) 3 (up) and run (go across) -2 (left), you will reach the point (1, -1).
So the slope is -3/2 and the y-intercept is 1/2, which is in answer c.

Answer the following questions using what you've learned from this unit. Write your responses
in the space provided.
1. Use the slope formula to answer Parts I, II, and III.
Part I: Find the slope of the line that passes through the following points. (6 points; 2 points
each)
A (10,4) and B (-2 , -5) C (-7 ,1) and D (7, 8)
Answer:
Part a) The slope of line that passes through the points A (10,4) and B (-2 , -5) is [tex]\mathbf{Slope=\frac{3}{4} }[/tex]
Part b) The slope of line that passes through the points C (-7 ,1) and D (7, 8) is [tex]\mathbf{Slope=\frac{1}{2} }[/tex]
Step-by-step explanation:
Part I: Find the slope of the line that passes through the following points.
Part a)
A (10,4) and B (-2 , -5)
We need to find slope of the line that passes through the given points.
The formula used is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We can take any two points and the slope will be same.
I am taking points A (10,4) and B (-2 , -5) and finding slope
We have [tex]x_1=10, y_1=4, x_2=-2,y_2=-5[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-5-4}{-2-10} \\Slope=\frac{-9}{-12}\\ Slope=\frac{3}{4}[/tex]
So, the slope of line that passes through the points A (10,4) and B (-2 , -5) is [tex]\mathbf{Slope=\frac{3}{4} }[/tex]
Part a)
C (-7 ,1) and D (7, 8)
We need to find slope of the line that passes through the given points.
The formula used is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We can take any two points and the slope will be same.
I am taking points C (-7 ,1) and D (7, 8) and finding slope
We have [tex]x_1=-7, y_1=1, x_2=7,y_2=8[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-1}{7-(-7)} \\Slope=\frac{7}{14}\\ Slope=\frac{1}{2}[/tex]
So, the slope of line that passes through the points C (-7 ,1) and D (7, 8) is [tex]\mathbf{Slope=\frac{1}{2} }[/tex]
