Which equation represents a line that passes though (-9,-3) and has a slope of -6
Answers
The equation for point-slope form is y - y1 = m(x - x1) where (x1, y1) is a point and m is the slope.
Substitute the values in to get y - (-3) = -6(x - (-9)).
Now, simplify a little bit.
y + 3 = -6(x + 9)
There’s the answer.
Please consider marking this answer as Brainliest to help me advance.
Answer:
D
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = - 6 and (a, b) = (- 9, - 3), thus
y - (- 3) = - 6(x - (- 9)), that is
y + 3 = - 6(x + 9)

What is 45,728 rounded to The nearest hundred
Answers
45,700
You either go up from 5-9 or down for 1-4.
Example:
56,891 to the nearest hundred.
An 8 is in the hundreds place so it will either be 56,800 or 56,900 depending on if you go up or down. Start at the ones place. The number is 1 so you take that down. Then you have 56,890. Next you go to the tens place. A 9 would go up so you then have 56,900. You are now in the hundreds place so you have solved the problem.
Answer:
45,700
Step-by-step explanation:
Go to the hundreds place and look at the number behind it. It's a 2. If you are rounding and the number behind it is 4 or less, you would keep it the same. If the number behind it is 5 or more, then you would round up. So, the answer is 45,700.
Find The angle of CBD
Answers
Answer:
Angle CBD is 125°.
Step-by-step explanation:
Remember that the sum of all the interior angles of a triangle is 180°. We know two of these angles from the diagram for problem #3: 67° amd 58°. Thus, angle ABC is 180° less the sum of 67° and 58°, or 180° - (67° + 58°), which comes out to 180° - 125°, or 55°.
This 55° and angle CBD are supplementary angles. In other words, 55° + <CBD must sum up to 180°. Subtracting 55° from 180° yields 125°.
Angle CBD is 125°.
Answer:
125°Step-by-step explanation:
We know that ∠CBD = ∠ACB + ∠CAB [ External Angle of a Triangle theorem]
∠CBD = 58° + 67° = 125°

Step-by-step explanation:
Answer: Add the volume of a rectangular prism to the volume of a triangular prism.
Step-by-step explanation:
A. Find the volume of a pyramid.
Neither of the shapes shown are a pyramid and there should be two shapes added together.
B. Find the volume of a rectangular prism.
There should be two shapes being added together, however this is one of the shapes shown.
C. Add the volume of a rectangular prism to the volume of a triangular prism.
This is the answer because the bottom shape of the house is a rectangular prism since there are six faces all with four sides. The top shape is a triangular prism because two of the faces are triangles and the other three are rectangles. This shape would not be a pyramid because in order for it to be categorized that way it would need at least four triangular faces that connect at a point.
D. Add the volume of a rectangular prism and a pyramid.
The triangular prism is shown, however the shape used to represent the roof of the house would be classified as a rectangular prism.
A car is traveling at a rate of 99 kilometers per hour. What is the car's rate in meters per second? How many meters will the car travel in 10 seconds?
Answers
Answer:
The answer is 16.5 meters in 10 seconds
Step-by-step explanation:
First you divide 99 by 60 seconds
When you get 1.65 you multiply it by 10 second.
When you multiply 1.65 by 10 second you get 16.5 meters in 10 seconds
The car will travel 275 meters in 10 seconds.
First, find how many meters per hour it is traveling. There are 1,000 meters in one kilometer, so there are 99,000 meters in 99 kilometers.
Now, find how many meters per minute the car is traveling by dividing 99,000 by 60 to get 1,650 meters per minute.
Finally, divide by 60 again to find the number of meters per second. 1,650 divided by 60 is 27.5, so the car is traveling at a rate of 27.5 meters per second.
To answer the second question, multiply the number of meters per second by the number of seconds to get the number of meters. 27.5 meters per second times 10 seconds is 275 meters in 10 seconds.

because when x = 3, y = -2
D)
(1, 6) Rejected
because when x = 0, y = 6
F)
(-5, 9) Rejected
because when x = 4, y = 9
Answer:
The correct options are A, D and E.
Step-by-step explanation:
The given set of ordered pairs represents a function
[tex]f=\{(-5, 3), (4, 9), (3, -2), (0, 6)\}[/tex]
We need to find THREE ordered pairs that could be added to the set that would allow f to remain a function.
A relation is a function if there exist unique value of y for each value of x.
The x values for given function are -5, 4, 3 and 0.
If we add (-3,-2) in the given set, then we unique value of y for each value of x. So, option A is correct.
If we add (4,0) in the given set, then we have y=0 and y=9 at x=4. Since the set have more than one value of y for same x-value, therefore option B is incorrect.
If we add (0,-1) in the given set, then we have y=-1 and y=6 at x=0. Since the set have more than one value of y for same x-value, therefore option C is incorrect.
If we add (1,6) in the given set, then we unique value of y for each value of x. So, option D is correct.
If we add (2,3) in the given set, then we unique value of y for each value of x. So, option E is correct.
If we add (-5,9) in the given set, then we have y=9 and y=3 at x=-5. Since the set have more than one value of y for same x-value, therefore option F is incorrect.
Therefore the correct options are A, D and E.

Which lines in the graph have a slope greater than 1 but less than 2?
line 1
line 2
line 3
line 4
line 5
Answers
Arrange each of their equations such that it becomes y=mx + c, where m and c are constants (they don't change and cannot vary).
Then, m, representing the slope (or gradient) will help you find the answer. The answer will be the line which has an m with a value greater than 1 anf les than 2.
Otherwise, if you don't have their equations, you can find their gradient (or slope) through the equation (y1 - y2)/(x1 - x2) where (x1, y1) and (x2, y2) are points on the same line. Do this for each of them and find each of their gradients/slopes before comparing them and finding the answer

Step-by-step explanation:
The equation is y=2x+4
Andy's assertion is incorrect because the correct equation for the given data must include a y-intercept term. Hence, the equation would be of the form y = mx + b, with the slope m being 2 and the y-intercept b being 4. For this dataset, the equation would be y = 2x + 4.
Explanation:Andy's statement that he can write an equation of the form y=mx for the given values is incorrect. If we look at the table, we see that as x increases by 1 unit, y increases by 2 units. This indicates that the slope of the line (m) is 2. However, the y-intercept is 4, not 0, hence our equation should have a form y = mx + b, where b ≠ 0. So, for this data, a correct equation would be y = 2x + 4.

The diameter of a pizza is 12 inches. What is its area?
Answers
Answer: 113.0973 [tex]in^{2}[/tex]
Step-by-step explanation:
If the diameter of the circle is 12", then the radius is 6" (half the diameter), and the area "A" is (approximately) 3.14 * 6^2 or about 113.04 sq. in. The calculation is approximate because 3.14 is a rounded value for pi. But the correct answer is 113.0973 not 113.04 because it's giving you the answer compared to SQUARE, but we need the answer in Inches. So that was just an example.
* Hopefully this helps:) Mark me the brainliest:)
The area is approximately 113.097 square inches.
To find the area of a pizza with a diameter of 12 inches, we follow these steps:
First, find the radius of the pizza. The radius is half of the diameter. So, radius = diameter / 2 which gives: radius = 12 inches / 2 = 6 inches.Next, use the formula for the area of a circle: A = πr². Here, π (pi) is approximately 3.14159.Substitute the radius into the formula: A = π × (6 inches)² = π × 36 square inches.Finally, calculate the area: A = 3.14159 × 36 ≈ 113.097 square inches.Therefore, the area of the pizza is approximately 113.097 square inches.
