On a coordinate grid, where is the center of this circle?
x² + y² = 2
A)
(-1, -1)
B)
(0,0)
(1.1)
D)
(2, 2)
Answer:
Option B) (0,0) is the correct answer.
Step-by-step explanation:
Given equation of circle is:
[tex]x^2+y^2 = 2[/tex]
The general form of equation of circle with center at (h,k) and radius r is given by:
[tex](x-h)^2+(y-k)^2 = r^2[/tex]
The given equation of circle can also be written as:
[tex](x-0)^2+(y-0)^2 = 2[/tex]
Comparing it with the general form of equation, we get
h = 0 , k = 0
So the center is (0,0)
Hence,
Option B) (0,0) is the correct answer.

i need a answer quickly! solve the division problem using a model a boy scout has 3 meters of rope he cuts the rope into cords 3/4 m long how many cords will he make
how can I find the slope to this I need help
Answer:
Your slope is -1
Step-by-step explanation:
Find the change in x and the change in y and put it in change in y over change in x.
Δx = -1 - -2 = 1
Δy = -1 - 0 = -1
Slope = rise over run = Change in y over change in x = Δy/Δx = -1/1
Therefore the slope is -1/1 which is written as just -1

Step-by-step explanation:
√2x-3-3=6
√2x-3=6+3
√2x-3=9
2x-3=9^2
2x=81+3
X=84/2
X=42
So value of X is 42

The indoor climbing gym is a popular field trip destination. This year the senior class at High
School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 14 vans and 5 buses with 329 students. High School B rented and filled 11 vans and 5 buses with 281 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.
Answer:
Step-by-step explanation:
14 x + 5y = 329
11x + 5y = 281(vans is x and busses are y)
cancel out 'y' by making the '5y' in 11x + 5y = 281 negative
-1 (11x + 5y = 281) =
-11x -5y = -281
insert second equation
-11x -5y = -281
14x + 5y = 320
3x = 48
x = 16
substitute vans in one equation
11(16) + 5y = 281
5y = 105
y = 21

The graph shows a proportional relationship between the number of miles and the number of hours Marco bikes.
What equation relates the distance, y, and the time, x? Enter your answer in the box
Please, this is urgent!
Answer:
15
Step-by-step explanation:
Its pretty simple
The equation that relates the distance (y) and the time (x) is → y = 15x.
What is the general equation of a Straight line?The general equation of a straight line is -
y = mx + c
where -
m is slope of line
c is the y - intercept
Given is a graph that shows a proportional relationship between the number of miles and the number of hours Marco bikes.
First we will find the slope of the straight line. Take two set of coordinates from the graph. We will take → (1, 15) and (2, 30).
The slope of the line can be calculated using the formula -
m = (y₂ - y₁)/(x₂ - x₁)
m =(30 - 15)(2 - 1)
m = 15
The line passes through the origin so its y - intercept (c) will be zero. So, we can write the equation as → y = 15x.
Therefore, the equation that relates the distance (y) and the time (x) is → y = 15x.
