Answer:
The coordinate of B is (6,0)
Step-by-step explanation:
Given;
coordinate of A = (-4,2) = (x₁, y₁)
coordinate of M = (1,1)
let coordinate of B = (x₂, y₂)
Mid-point is given by;
[tex]M = \frac{X_1 + X_2}{2} , \frac{Y_1 + Y_2}{2}\\\\M= (1,1)\\\\1,1 =\frac{X_1 + X_2}{2} , \frac{Y_1 + Y_2}{2}\\\\ \frac{X_1 + X_2}{2} = 1 ----equation (1)\\\\\frac{Y_1 + Y_2}{2} = 1 -----equation(2)\\\\Solving \ equation(1)\\\\\frac{-4+ X_2}{2} = 1\\\\-4+ X_2 = 2\\\\X_2 = 2+4\\\\X_2 = 6\\\\Solving \ equation(2)\\\\\frac{Y_1 + Y_2}{2} = 1\\\\\frac{2+ Y_2}{2} = 1\\\\2+Y_2 = 2\\\\Y_2 = 2-2\\\\Y_2 = 0\\\\B = (X_2, \ Y_2)\\\\B = (6, \ 0)[/tex]
Therefore, the coordinate of B is (6,0)
the ratio of boys to girls in a class is 4 : 5
a) what is the fraction of boys in the class
b) what is the fraction of girls in the class
Answer: 4/9 of the class are boys and 5/9 of the class are girls.
Step-by-step explanation:
There are 9 nine students in total in the class since 4 + 5 = 9.Input the amount of boys and girls there are in the class in the numerator and have 9 as the denominator. 4/9 of the class are boys and 5/9 of the class are girls.4 questions, if you dont know all of them please just help with at least 1. i have crossed out the ones i dont need help with. help me for brainliest <3

(6.0 x 10 ^4) + (3.0 x 10 ^4)
Answer:
9x10000 or 9.0 x 10^4
Step-by-step explanation:
6x104+3x104
Simplifies to:
9x10000
=9x10000
Mark Brainliest?
Answer:
9.0 x 10^4
Step-by-step explanation:
(6.0 x 10 ^4) + (3.0 x 10 ^4)
=> 6 x 10000 + 3 x 10000
=> 10000(6+3)
=> 9(10000)
=> 9 x 10^4
=> 9.0 x 10^4
The fifth term of a geometric sequence is 32 and the eighth term is 4.
(a) Find the ratio. (2 marks)
(b) Find the first term. (2 marks)
(C) Find the sum of the first 50 terms of the sequence. (3 marks)
What is the first term?
Answer:
a. 1/2
b. 512
c. 1024
Step-by-step explanation:
The nth term of a geometric progression can be written as;
Tn = ar^n-1
where a is the first term, r is the common ratio and n is the term number
From the question;
Fifth term = ar^4 = 32
Eight term = ar^7 = 4
a. We want to find the common ratio
What to do here is that we can divide the 8th by the 5th term
ar^7/ar^4 = 4/32
r^3 = 1/8
r^3 = (1/2)^3
Thus r = 1/2
b. First term
we can make a substitution in any of the two given terms
Let’s use the fifth term
ar^4 = 32
a * (1/2)^4 = 32
a * 1/16 = 32
a = 16 * 32
a = 512
C. Sum of the first 50 terms
To calculate this, we use the sum of terms formula
Sn = a(1- r^n)/1-r
a = 512 , n = 50 and r = 1/2
Making the substitution;
Sn = 512(1-(1/2)^50)/1-1/2
Kindly note that (1/2)^50 will be infinitesimally small and will be close to zero
So we can approximate (1/2)^50 to be zero
Hence;
Sn = 512(1-0)/0.5
Sn = 512/0.5
Sn = 1024
How many solutions does the following system of equations have?
v=3x +2
2v=5x+8
Answer:
The answer is C, zero solutions.
Step-by-step explanation:
y = 5/2x + 2
2y = 5x + 8
Multiply 2 to the first equation.
2y = 5x + 4
Compare it with the other equation
2y = 5x + 4
2y = 5x + 8
Cancel 2y and 5x on both sides.
Remaining:
4 = 8
4 ≠ 8. Therefore, the answer is C, zero solutions.
7) Line Segment PR is 5 ft. Find the length of Line Segment PQ and QR. (Hint: use the segment addition postulate.)
Answer:
PQ = 1 ft
QR = 4 ft
Step-by-step explanation:
From the picture attached,
Segment PR has been divided into two parts by a point Q.
Length of segment PR = 5 feet
Length of segment PQ = (15x - 2) ft
Length of segment QR = (5x + 3) ft
Since, PR = PQ + QR
5 = (15x - 2) + (5x + 3)
5 = 20x + 1
20x = 4
x = [tex]\frac{4}{20}[/tex]
x = 0.2
PQ = 15x - 2
= 15(0.2) - 2
= 3 - 2
= 1 ft
QR = 5x + 3
= 5(0.2) + 3
= 1 + 3
= 4 ft
simplify the following expressions ( use distributed property )
Answer:

Points P, R, and S, are collinear such that R lies on PS. It is known that the ratio of
PR: RS = 1/3}. Find the location of coordinate R if P is located at (-2,-6) and is
located at (10,30).
Answer:
1,3
Step-by-step explanation:
Sorry if my English is bad
or if my answer is wrong but from my understanding,
as you can recognize from the photos, we need to understand what a collinear is. Collinear are points that are lying in the same straight line. Thus, we can transform the ratio to fractions which means 1 : 3 into 1/3
Hence, the coordinate R is 1/3 between P and S.
Therefore, to determine coordinate R, we must use the formula that is provided. P is (X1, Y1), S is (X2,Y2), M1 is 1 or the Numerator and M2 is 3 or The denominator.

Step-by-step explanation:
sec (thita) = squrt (5)
squaring on both sides:
sec^2 (thita) = 5 - equation 1
1 + tan^2 (thita) = 5
tan^2 (thita) = 4
tan (thita) = 2.
= tan (thita) - squrt(5)sin(thita)
= 2 - squrt(5) x 2/ squrt(5)
= 0
from eqn - 1
sec(thita) = squrt(5)
cos(thita) = 1/ squrt(5)
sin(thita) = squrt ( 1- 1/(squrt (5))^2)
sin(thita) = 2/ squrt(5) .

the midpoint of ab is m (3,-4). If the coordinates of A are (8,-5), what are the coordinates of B
Answer:
work is attached and shown
The coordinates of the midpoint will be (-2,-3).
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line. Given that the midpoint of AB is M(3,-4) and the coordinates of A are (8, -5).
The midpoint will be calculated by using the formula below:-
( 8 + x ) / 2 = 3
( 8 + x ) = 6
x = -8 + 6 = -2
( -5 + y ) / 2 = -4
( -5 + y ) = -8
y = -8 + 5 = -3
Therefore, the coordinates of the midpoint will be (-2,-3).

Let's solve your equation step-by-step.
3x−5x+14=26
Step 1: Simplify both sides of the equation.
3x−5x+14=26
3x+−5x+14=26
(3x+−5x)+(14)=26(Combine Like Terms)
−2x+14=26
−2x+14=26
Step 2: Subtract 14 from both sides.
−2x+14−14=26−14
−2x=12
Step 3: Divide both sides by -2.
−2x
−2

When traveling to the airport, your checked baggage must be under 50 pounds. There are about 2.2 lbs. in one kilogram. What is this weight in kilograms? Round to the nearest tenth. *
I need help
Answer:
22.7 kg
Step-by-step explanation:
Using a conversion factor:
50 lb × (1 kg / 2.2 lb) = 22.7 kg
Using a proportion:
1 kg / 2.2 lb = x kg / 50 lb
2.2x = 50
x = 22.7
x+2/2x+3=y+1 rearrange and make x the subject
Answer:
x = y/2 - 1
Step-by-step explanation:
Solve for x:
2 x + 3 = y + 1
Hint: | Isolate terms with x to the left hand side.
Subtract 3 from both sides:
2 x = y - 2
Hint: | Solve for x.
Divide both sides by 2:
Answer: x = y/2 - 1
