the equation y+6=1/3(x-9) is written in point-slope form. What is the equation written in slope-intercept form?
A. y= 1/3x-3
B. y=1/3x+9
C.y=1/3x-9
D. y=1/3x+3
y+6=1/3(x-9)
Moved all terms from left to right that doesn't contain y
Y=-6 +1/3x-3
Simplify
Y=1/3x-9
Your answer is c.
Answer: [tex]y=\dfrac{1}{3}x-9[/tex]
Step-by-step explanation:
The equation of a line in slope -intercept form is written as :-
[tex]y=mx+c[/tex]
The given equation : [tex]y+6=\dfrac{1}{3}(x-9)[/tex]
To write the given equation in slope - intercept form , we need to first solve the right -hand sides in the equation.
[tex]y+6=\dfrac{1}{3}(x-9)\\\\\Rightarrow\ [tex]y+6=\dfrac{1}{3}x-3\\\\\Rightarrow\ y=\dfrac{1}{3}x-3-6\\\\\Rightarrow\ y=\dfrac{1}{3}x-9[/tex]
Hence, the equation written in slope-intercept form : [tex]y=\dfrac{1}{3}x-9[/tex]
A dartboard has 8 sections of equal area. The letters represent colors red (R), yellow (Y), blue (B), and green (G). Complete the probability distribution for a dart that hits the board at a random location.
Red: 1/8
Yellow:?
Green: 3/8
Blue: 1/8
Answer:
3/8
Step-by-step explanation:
If you add the top number of all the fractions you get 5. You need to get to 8, 8-5=3 so that means yellow has to be 3/8.
Solve the inequality-2(6+s)_>-15-2s
Answer:
s can take any real value.
Step-by-step explanation:
Given that
-2(6+s)_>-15-2s
Distribute -2 over 6+s
-12-2s >= -15-2s
Simplify both the sides
Add 2s to both the sides.
We get 2s cancel out and -12>=-15 which is true.
Hence the given inequality is valid for all values of s.
This is a special case of inequality which has infinite number of solutions.
s can take any real number and this inequality is valid.
Answer:
Solution of inequality: -12 ≥ -15 Which is true.
Step-by-step explanation:
Given data:
Equation:-2(6+s)_>-15-2s
-2(6+s)_>-15-2s
=-12 - 2s ≥ - 15 -2s
By dividing -2s on both sides:
= -12 - 2s/-2s ≥ - 15 -2s/-2s
= -12 ≥ -15
-2(6+s)_>-15-2s = -12 ≥ -15
If the area of a park is exactly halfway between 2.4 and 2.5 acres, what is the area of the park
The area of the park is 2.45 acres.
The area of a park is determined to be exactly halfway between 2.4 acres and 2.5 acres. To find this midpoint or average, we add the two values together and then divide by 2.
First, we add 2.4 acres and 2.5 acres:
2.4 acres + 2.5 acres = 4.9 acres
Now, we divide this sum by 2 to find the midpoint:
Midpoint = 4.9 acres / 2 = 2.45 acres
Therefore, the area of the park is 2.45 acres. This means that it is precisely halfway between the two given values.
Understanding the midpoint or average is essential in various contexts, such as real estate, land measurement, and statistical analysis. In this case, it signifies that the park occupies an area that is equidistant from 2.4 acres and 2.5 acres. It can be seen as a balanced point between these two values, serving as a useful concept for situations where precision or fairness is required, such as in property assessments or distributing resources evenly.

15 * 28 = 420. Should be your answer.
how can one logically explain the distance formula?
Final answer:
The distance formula calculates the straight-line distance between two points on a coordinate plane using the Pythagorean theorem, which is applied to the differences in the x and y coordinates of the points to form a right triangle.
Explanation:
Explaining the Distance Formula
The distance formula is a way to calculate the straight-line distance between two points in a coordinate plane. This formula is derived from the Pythagorean theorem which states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). In other words, a² + b² = c².
To understand the distance formula, consider two points (x1, y1) and (x2, y2) on a coordinate plane. The difference in the x values (x2 - x1) and the y values (y2 - y1) represent the lengths of the legs of a right triangle, where the straight-line distance we are trying to find is the hypotenuse. Thus, by the Pythagorean theorem, the distance (d) can be found by taking the square root of the sum of the squares of these differences. The resulting distance formula is d = √((x2 - x1)² + (y2 - y1)²).
The distance formula logically extends the Pythagorean theorem to two-dimensional space, where distances on the plane are calculated irrespective of the orientation or position of the line connecting the two points.

By selling old CDs, Sarah has a store credit for $153. A new CD coat $18. What are the possible numbers of new CDs Sarah can buy? (Inequalities)
We can find the maximum number of CDs she can buy by dividing 153 by 18. The answer ends up being 8.5. Since she can't buy 0.5 of a CD, she can buy a maximum of 8 CDs. Written as an inequality, I think it should be x is less than or equal to 8. I hope this helps!

Hey there! Welcome to Brainly
We see that Damian earns $8 for every hour he works. This means that when x=1, Damian will earn 8 dollars, 2 he will earn $16, etc.
Since he constantly adds 8 every hour, it would look like this.
8+8+8+8+8+8+8.....
This is an example of multiplication.
The thing is, we are not sure how many 8's we are adding.
We can use the variable "x" to represent ANY number of 8's, or hours he worked.
We would multiply this x by 8 to show that he will earn $8 for EACH number of hours he works.
8 x x
The problem is, we cannot write our multiplication sign like this, because it looks just like our x we are using.
We can rewrite our multiplication symbol using · or we can just put our x right next to the eight. When a variable is right next to a constant, or number without a variable, it turns it into a mini multiplication equation, but in a simplified form.
8x
Now, we need to write this as an equation. We need to say that something else is equal to 8x. We could say, his money, which we can represent with as d.
Therefore, we could write our equation as d= 8x.

Tommy has a piece of toast that has butter on one side, and he dropped it twice. Both times, it landed with the butter side up. If he drops it 2 more times, what is the probability that it will have landed butter side up a total of 3 times?
Answer: 1/2.
Explanation:
First, note that since the previous drops have already happened, their result do not modify the occurrence of future results when the toast is dropped again.
In oder to have a total of three time landing butter side up, exactly, there are two possibilities:
Since there are two ways of totaling side up 3 times, you have to sum both chances.
1) Next drop butter side up and second drop butter side down:
1/2 × 1/2 = 1/4
2) Next drop butter side down and second one butter side up:
1/2 × 1/2 = 1/4
3) Add both probabilities: 1/4 + 1/4 = 1/2
And that is the answer: 1/2
Suppose three people ate a meal in a restaurant. The cost of each of their meals is m. One person intends to tip 10%, the second person intends to tip 15%, and the third person intends to tip 20%. Which expression represents the total amount that they'll pay?
A. 1.1m + 1.15m + 1.2m
B. 0.1m + 0.15m + 0.2m
C. 1.1m + 2.15m + 3.2m
D. 1 + 0.1m + 1 + 0.15m + 1 + 0.2m
For this case we have:
m represents the total cost of each meal. If people do not pay a tip, the total cost to pay would be:
[tex]m + m + m = 3m\\[/tex]
Person 1:
Without tip the cost of your meal is m.
You want to pay 10% tip
m -------------------> 100%
x --------------------> 10%
[tex]x =\frac{(10)(m)}{100} = 0.1m\\[/tex]
Thus, its cost will be:
[tex]C1 = m + 0.1m = 1.1m\\[/tex]
Person 2:
Without tip the cost of your meal is m.
m -------------------> 100%
x --------------------> 15%
[tex]x =\frac{(15)(m)}{100} = 0.15m\\[/tex]
Thus, its cost will be:
[tex]C2 = m + 0.15m = 1.15m\\[/tex]
Person 3:
Without tip the cost of your meal is m.
m -------------------> 100%
x --------------------> 20%
[tex]x =\frac{(20)(m)}{100} = 0.20m\\[/tex]
Thus, its cost will be:
[tex]C3 = m + 0.20m = 1.20m\\[/tex]
Thus, the total cost to pay will be:
[tex]C = 1.1m + 1.15m + 1.20m\\[/tex]
Answer:
[tex]C = 1.1m + 1.15m + 1.20m[/tex]

The angle of cba is 3.408* if you wanna know
cba is 3.408 and just ask if you want to know how
Which of these values could be the slope of the line? Check all that apply.
–2
-8/5
0
7/4
3
undefined
Answer:
7/4 or 3
Step-by-step explanation:
To determine the slope of the line , we look at the position of the line
From the given graph , the line goes up
When line goes up , the slope is positive
when a line goes down , the slope is negative
If we have a vertical line then slope is undefined
For horizontal line the slope is 0
Here the line goes up, so slope is positive
We pick the slope from the given option that is positive
7/4 or 3
