A: look at the graph, find the x axis of 2 and on the y axis 1.
B basically the center
C look for x axis of -4, y axis for 3
D x axis -2, y axis -5
E x axis 1, y axis -3
F Center then go up 4
G x axis -5, y axis 1
H x axis -2, y axis 0
All the points A(2, 1), B(0, 0), C(-4, 3), D(-2, -5), E(1, -3), F(0, 4), G(-5, 1), and H (-2, 0) are located on the graph.
What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
The collection includes all locations on the surface of the shape (x, f(x)) that make up a function of f's graph. We may alternatively say that the graph of f is the curve of y = f. (x). As a result, the diagram of an equation is a particular instance of the graphs of functions.
The points are given below.
A(2, 1), B(0, 0), C(-4, 3), D(-2, -5), E(1, -3), F(0, 4), G(-5, 1), and H (-2, 0)
All the points A(2, 1), B(0, 0), C(-4, 3), D(-2, -5), E(1, -3), F(0, 4), G(-5, 1), and H (-2, 0) are located on the graph.

A wildlife photographer photographs a crocodile and then paddles against a river current for 6 km. Then, hoping to photograph a hippopotamus, she paddles 15 km across a lake. She paddles across the lake for one hour longer than she paddled up the river. Find the speed of the boat as she paddles if the river current is 2 km/h (2 answers)
Answer:
Step-by-step explanation:
5 km/h or 6 km/h
Step-by-step explanation:
Let the speed of the boat be x
Speed against the current in the river is x - 2
Time in the river:
6/(x - 2)
Time in the lake:
15/x
The difference:
6/(x - 2) = 15/x - 1
Solve for x to find the speed of the boat
Multiply both sides by x(x - 2) to clear the fraction:
6x = 15(x - 2) - x(x - 2)
6x = 15x - 30 - x² + 2x
x² - 11x + 30 = 0
(x - 5)(x - 6) =0
x -5 = 0, x - 6 = 0
x = 5 km/h, x = 6 km/h

Solve the quadratic equation.
m^2/15 -3 = 2
The answer is [tex] 5 \sqrt{3} [/tex]
Explanation :[tex] \frac{ {m}^{2} }{15} - 3 = 2[/tex]
[tex] \frac{ {m}^{2} }{15} = 2 + 3[/tex]
[tex] \frac{ {m}^{2} }{15} = 5[/tex]
[tex] {m}^{2} = 5 \times 15[/tex]
[tex] {m}^{2} = 75[/tex]
[tex]m = \sqrt{75} [/tex]
[tex]m = \sqrt{25 \times 3} [/tex]
[tex]m = \sqrt{25} \times \sqrt{3} [/tex]

Calculate the measures of spread for Mrs Hampton's class data. Justify your
response by describing the process used to find each measure, (2 points)
The measures of spread include the range, quartiles and the interquartile range, variance and standard deviation. Let's consider each one by one.
Interquartile Range:
Given the Data -> First Quartile = 2, Third Quartile = 5
Interquartile Range = 5 - 2 = 3
Range: 8 - 1 = 7
Variance:
We start by determining the mean,
[tex]\:1+\:2+\:3+\:3+\:3+\:5+\:8 / 7 = 3.57[/tex]
n = number of numbers in the set
Solving for the sum of squares is a long process, so I will skip over that portion and go right into solving for the variance.
[tex]\sum _{i=1}^n\frac{\left(x_i-\bar{x}\right)^2}{n-1},\\\\=> SS/n - 1\\\\=> 31.714/7 - 1\\=> 5.28571[/tex]
5.3
Standard Deviation
We take the square root of the variance,
[tex]\sqrt{5.28571} = 2.29906[/tex]
2.3
If you are not familiar with variance and standard deviation, just leave it.

Determine whether the given value is a solution of the equation.
b
6; b =78
13
78 (select) a solution.
is 78 the solution or not
Answer:
78 is a solution
Step-by-step explanation:
The given equation is b/13 = 6
Therefore, by applying the multiplication property of equality, we have by multiplying both sides by 13, we have;
b/13 × 13 = 6 × 13
The 13 in the denominator of b/13 divides the 13 in the multiplicand to give 1, and we get the following equation
b/13 × 13 = b × 1
Therefore;
b/13 × 13 = b × 1 = 6 × 13 = 78
b × 1 = 78
By the multiplicative identity property of '1', we get;
b × 1 = 1 × b = b
∴ b × 1 = b = 78
b = 78
∴ 78 is a solution of the equation.
Edwin has £300 in his savings account His bank offers him a fixed 5% simple interest rate per annum for a period of 3 years How much internet will he have earned after 3 years?
Answer: £45
Step-by-step explanation:
First find the amount of simple interest in on year:
= Amount * simple interest rate
= 300 * 5%
= £15
Now that you have the annual interest, the 3 year interest is:
= 15 * 3 years
= £45

Consider the following system of linear equations:
2x+2y = 6
4x – 6y = 12
Answer:
x=3, y=0
Step-by-step explanation:
Answer:
(3, 0 )
Step-by-step explanation:
Given the 2 equations
2x + 2y = 6 → (1)
4x - 6y = 12 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the x- term
- 4x - 4y = - 12 → (3)
Add (2) and (3) term by term to eliminate x
0 - 10y = 0
- 10y = 0 ⇒ y = 0
Substitute y = 0 into either of the 2 equations and solve for y
Substituting into (1)
2x + 2(0) = 6
2x = 6 ( divide both sides by 2 )
x = 3
solution is (3, 0 )

If, on their own, it takes 6 hours for Person A to complete a task and 9 hours for Person B to complete the same task, then how many hours would it take if they worked together? Estimate your answer to 4 places after the decimal, if necessary.
Answer:
Step-by-step explanation:
A does 1/6 of the task per hour.
B does 1/9 of the task per hour.
Together, they do 1/6+1/9 = 5/18 of the task per hour, finishing in 18/5 hours.
18/5 = 3.6 hours

Step-by-step explanation:
In triangle AOB
OA = OB (radii of same circle)
[tex] m\angle OAB = m\angle OBA =20\degree [/tex]
[tex] m\angle AOB = 180\degree - (20\degree +20\degree) [/tex]
[tex] m\angle AOB = 180\degree - 40\degree [/tex]
[tex] m\angle AOB = 140\degree [/tex]

Step-by-step explanation:
∠N= 63°(angles opposite to equal sides)
2∠y+63+63=180°(angle sum property)
2∠y=54°
∠y=27°
27°+63°+∠x=180°(ASP)
