Find the midpoint of the segment with the following endpoints.
(5,9) and (0,3)
Answer:
(5/2, 6)
Step-by-step explanation:
(x, y)=[(5+0)/2, (9+3)/2]
(x, y)=[5/2, 12/2]
(x, y)=(5/2, 6)
The Midpoint of the Line Segment that has the endpoints (5,9) and (0,3) is (5/2,6).
What is the line segment?In geometry, a line segment is a part of a line that is bounded by two end points, and contains every point on the line that is between end points.
Now it is given that,
The endpoints of line segment is (5,9) and (0,3)
So, x₁ = 5
y₁ = 9
x₂ = 0
y₂ = 3
Let (x,y) be the midpoint of segment .
∴To find the midpoint of segment we have,
(x,y) = {[(x₁+x₂ )/2] , [(y₁+y₂ )/2]}
Put the values, we get
(x,y) = (5+0)/2 , (9+3)/2
solving them,
(x,y) = {(5/2) ,(12/2)}
or,
(x,y) = (5/2,6)
which is the required midpoint of the line segment.
Hence,the Midpoint of the Line Segment that has the endpoints (5,9) and (0,3) is (5/2,6).

given the following functions f(x) and g(x), evaluate (gºf)(-2). Enter answer.
f(x)=2x^2+2x-5
g(x)=-1/-4x+6
Answer:
the composition results in [tex]\frac{23}{4}[/tex]
Step-by-step explanation:
Assuming that what you typed for function g is correct (looks a bit peculiar, but we will use it as typed):
[tex]g(x)=-\frac{1}{-4x} +6[/tex]
gof(-2) can be understood as: g(f(-2)), so what we need to do is to find the value for f(-2) using its given expression, and using then the obtained value as input for g(x):
[tex]f(x)=2x^2+2x-5\\f(-2)=2\,(-2)^2+2\,(-2)-5\\f(-2)= 8-4-5\\f(-2)= -1[/tex]
So, we now evaluate g(-1):
[tex]g(x)=-\frac{1}{-4x} +6\\g(-1)= -\frac{1}{-4(-1)} +6\\g(-1)= -\frac{1}{4} +6\\g(-1)=\frac{23}{4}[/tex]
Use the map to find the distance between Brookline and Davenport to the nearest tenth
Answer:
8.5
Step-by-step explanation:
The distance between Brookline(8, 2) and Davenport(5, 10) can be calculated using the distance formula given as [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y1)^2} [/tex].
Let,
[tex] Brookline(8, 2) = (x_1, y_1) [/tex]
[tex] Davenport(5, 10) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(5 - 8)^2 + (10 - 2)^2} [/tex]
[tex] d = \sqrt{(-3)^2 + (8)^2} [/tex]
[tex] d = \sqrt{9 + 64} = \sqrt{73} [/tex]
[tex] d = 8.5 [/tex] (nearest tenth)
Which expression is equivalent to 2(n - 7) - 3(2 -6n)
20(n - 1)
Step-by-step explanation:2(n - 7) - 3(2 -6n) =
= 2n - 14 - 6 + 18n
= 20n - 20
= 20(n - 1)
The value of the equation A = 2(n - 7) - 3(2 -6n) is
A = 20 ( n- 1 )
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A
Now , the equation A = 2( n - 7 ) - 3( 2 - 6n )
The equation can be simplified as
A = 2(n) - 2(7) - 3(2) + 3(6n)
A = 2n - 14 - 6 + 18n
Now , on adding the similar terms in the equation , we get
A = 2n + 18n - ( 14 + 6 )
A = 20n - 20
Taking the common term of 20 , we get
A = 20 ( n - 1 )
Therefore , the value of A is 20 ( n - 1 )
Hence , The value of the equation A = 2(n - 7) - 3(2 -6n) is A = 20 ( n- 1 )

L1 : y = 2x , (2) find the equation of the line L2 perpendicular to L1 passing through the point P = (1, 2).
Answer:
2y+x = 5Step-by-step explanation:
Given the line L1 as y = 2x perpendicular to an unknown line L2 passing through the point P = (1, 2), we are to find the equation of line L2. to find the equation of the line L2, we will use the point-slope equation of a line expressed as y-y₀ = m(x-x₀)
m is the slope of the unknown line
(x₀, y₀) is the given point.
First is to get the slope of the known line:
comparing the line L1: y = 2x with the standard equation of the line y = mx+c, it can be seen that m = 2
Then we will calculate the slope of the required line.
Since L1 is perpendicular to L2, the product of their slope will be -1 i.e
mm₁ = -1 where m₁ is the slope of the required line L2.
Given m =2
m₁ = -1/m
m₁ = -1/2
Finally we will calculate the equation of line L2 by substituting the slope of line L2 and the point in the point slope equation above;
y-y₀ = m(x-x₀)
Given (x₀, y₀) = (1,2) and m₁ = -1/2
y-2 = -1/2(x-1)
open the parenthesis
y-2 = -x/2+1/2
multiply through by 2:
2y-4 = -x+1
2y+x = 1+4
2y+x = 5
Hence the equation of the line L2 is 2y+x = 5
