Coordinates of point B are (5x₂+6x₁)/11 and (5y₂+6y₁)/11
What is the section formula in co-ordinate geometry?When the line segment is divided internally in the ration m:n, we use this formula. That is when the point C lies somewhere between the points A and B. p= (mx₂+nx₁)/(m+n) & q= (my₂+ny₁)/(m+n)
Given here, point B on AC Such that the ratio of AB to AC is 5:6
Let the point B(p,q) internally divide the line joining points A(x₁, y₁) and C(x₂, y₂) in the ratio m : n , then,
p= (mx₂+nx₁)/(m+n)
q= (my₂+ny₁)/(m+n)
Here. m=5 and n=6
p=(5x₂+6x₁)/11 , q=(5y₂+6y₁)/11
Hence, Coordinates of point B are (5x₂+6x₁)/11 and (5y₂+6y₁)/11

Convert the equations into slope intercept form,
then identify the slope and y-intercept.
1. -x + y = 3
m=

2. -4x + 2y = 6
m=
b=
3. 2x + =3
m=
b=
Answer:
1. -x + y = 3
m= 1
b= 3
2. -4x + 2y = 6
m= 2
b= 3
Step-by-step explanation:
Slope intercept is form to write equation for straight line.
It is represented as y = mx+ b
where m is the slope of line
B is the y intercept (pint on y axis where the line crosses y axis)
________________________________________________
Given
1. -x + y = 3
we need to convert this line in form of y = mx+ b
-x + y = 3
to do this we have to move - x from LHS to RHS
it can be done by adding both side +x which will eleminate -x from LHS
-x + y + x = 3 + X
=>y = 3 + x
=> y = x +c
Thus comparing it with slope form line: y = mx+ b
m =1
b = 3
__________________________________________________
Given
1. -4x + 2y = 6
we need to convert this line in form of y = mx+ b
-4x + 2y = 6
to do this we have to move + 4x from LHS to RHS
it can be done by adding both side +4x which will eleminate -4x from LHS
-4x + 2y + 4x= 6 +4x
=>2y =6 +4x
Now we have to remove 2 from 2y =6 +4x
To do this we divide both side by 2 . now we have equation
=> 2y/2 =(6 +4x)/ 2 = 6/2 + 4x/2
=> y = 3 + 2x
Thus comparing it with slope form line: y = mx+ b
m = 2
b = 3
__________________________________
Third part has 2x + =3 has y missing
it can be solved similarly.
say in place of y we have my where m is coefficient of y
2x + my =3
to do this we have to move + 2x from LHS to RHS
it can be done by subtracting -2x from both side which will eleminate 2x from LHS
2x + my -2x =3 -2x
=>my =3 -2x
Now we have to remove m from my =3 -2x
To do this we divide both side by m . now we have equation
=> my/m =(3 -2x)/ m = 3/m -2x/m
=> y = 3/m - 2x/m
Thus comparing it with slope form line: y = mx+ b
m = -2/m
b = 3/m

Rearrange the equation so q is the independent variable.
9q-4=3r-6
r = __
Answer:r=3q+2/3
Step-by-step explanation:
Step 1: Flip the equation.
3r-6=9q-4
Step 2: Add 6 to both sides.
3r-6+6=9q-4+6
3r=9q+2
Step 3: Divide both sides by 3.
3r/3=9q+2/3
r=3q+2/3
Hopefully it’s right
Rearranging the equation, so q is the independent variable as r=(9q+2)/3.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 9q-4=3r-6.
Now, 9q-4+6=3r
3r=9q+2
r=(9q+2)/3
Therefore, rearranging the equation, so q is the independent variable as r=(9q+2)/3.

Step-by-step explanation:
Batman, who is having a slow year for crime, has resorted to saving cats from very tall buildings. Our fearless 6 foot tall hero is 40 feet from the the Petsmart building the cat was trying to break in to, in order to get his paws on the pumpkin spice cat nip. Batman sights the top of the building at a 30° angle, how high is the building?
Answer:
29.094 feet tall
Step-by-step explanation:
tan(30) = [tex]\frac{x}{40}[/tex]
so tan is opposite over adjacent which means that we should be able to solve for the opposite as we have the angle (30) and the distance from Batman to to building, which is (40 feet), with these numbers you will do, tan(30) = [tex]\frac{x}{40}[/tex] and from that you will solve for x, and from x you add the 6 foot of batmans height

three angles measuring 259, 65°, and 90°
three angles measuring 509, 50°, and 50°
three sides measuring 5 in., 12 in., and 13 in.
three sides measuring 4 ft, 8 ft, and 10 ft
Answer:
three sides measuring 4 ft, 8 ft, and 10 ft
Step-by-step explanation:
To choose which dimensions that can create more than one triangle, we consider the given values carefully and how possible it will be to construct.
The only dimensions given in the option that will be possible to create more than one triangle from it, is three sides measuring 4 ft, 8 ft, and 10 ft.
4 ft, 8 ft, and 10 ft are in simple multiple of 2
4 ft, 8 ft, and 10 ft = 2 (2 ft, 4 ft, and 5 ft ), with this we can construct two triangles with three sides measuring 2 ft, 4 ft, and 5 ft.

y = (-1/80)x^2 +2x
Step-by-step explanation:
The graph of the equation for the arch will go through the points ...
(0, 0), (160, 0), (80, 80)
We can start by making use of the zeros to write the function ...
y = a(x -0)(x -160)
To make the graph go through the point (80, 80), we must have ...
80 = a(80 -0)(80 -160) = (-80^2)a
-1/80 = a . . . . . . divide by the coefficient of "a"
So, our equation is ...
y = (-1/80)x(x -160)
y = (-1/80)x^2 +2x

Find the value of x.
Answer:
x = 61
Step-by-step explanation:
x and 29 are complementary angles so they add to 90 degrees
x+29 = 90
Subtract 29 from each side
x+29-29 = 90-29
x = 61
Answer:
61 degrees = x
Step-by-step explanation:
Since angle measures x and 29 are complementary angles, subtract 29 from 90 degrees.
90 - 29 = 61 degrees is the value of x

How do you find the median of a data set when you have an even number of values?
Answer:
If there is an even number of numbers, the median is the average of the two numbers in the middle.
Step-by-step explanation:
To find the median of any set of numbers, put them in order from smallest to greatest. If a number occurs more than once, list it more than once. The number in the middle is the median. If there is an even number of numbers, the median is the average of the two numbers in the middle. For your first example, we line them up: 3, 6, 6.
Answer:
Set them from least to greatest and remove one from each side until you find the middle number! If you're left with 2, add them both and divide by 2.
