Answer:
y - 4 = -1/2(x+6).
Step-by-step explanation:
The equation of the line is: y - y0 = m(x-x0)
If the line passes through the points (x1, y1)=(-6, 4) and (x1, y1)=(2, 0). Then, the slope is:
[tex]m = \frac{y1-y0}{x1-x0} = \frac{0-4}{2-(-6)} = -\frac{1}{2} [/tex]
Then, the equation is: y - 4 = -1/2(x+6).
Solve the formula C = td for d.
Answer:
d = C /t
Step-by-step explanation:
C = td
We want to isolate d, so divide each side by t
C/t = td/t
C/t = d
d = C /t
Answer: c/d = t
Since d is being multiplied by t, to get d by itself we simply divide both sides of the equation by t and we have c/d = t which is our final answer.

This equation represents the given horizontal line is y = - 7. the correct option is d.
To find the equation of the line passing through the points (-10, -7) and (3, -7), we can use the point-slope form of a linear equation:
The point-slope form is given by: y - y₁ = m(x - x₁)
where (x₁, y₁) are the coordinates of one of the points on the line, and m is the slope of the line.
First, let's calculate the slope (m) using the two points:
m = (change in y) / (change in x)
m = (-7 - (-7)) / (3 - (-10))
m = 0 / 13
m = 0
Now, we have the slope (m = 0), and we can choose either of the given points to plug into the equation. Let's use the point (-10, -7):
y - (-7) = 0(x - (-10))
y + 7 = 0
Now, we can simplify the equation:
y = -7
So, the equation of the line passing through the points (-10, -7) and (3, -7) is y = -7. This equation represents a horizontal line at y = -7, as the slope is 0.

c. y- 1 = -5(x - 2)
D. y + 1 = 5(x + 2)
SUBMI
Answer:
A
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 = - 5 and (a, b) = (2, - 1), so
y - (- 1) = - 5(x - 2), that is
y + 1 = - 5(x - 2) → A
The point-slope form of a line with slope -5 that contains the point
(2,-1) is,
⇒ y + 1 = - 5 (x - 2)
Since, The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Here, Given that;
Slope = - 5
Point on line = (2, - 1)
Hence, The point-slope form of a line with slope -5 that contains the point
(2,-1) is,
⇒ y - y₁ = m (x - x₁)
⇒ y - (- 1) = - 5 (x - 2)
⇒ y + 1 = - 5x + 10
⇒ y =- 5x + 10 - 1
⇒ y = - 5x + 9
Thus, The point-slope form of a line with slope -5 that contains the point
(2,-1) is,
⇒ y + 1 = - 5 (x - 2)

An olympian swam the 200-meter freestyle at a speed of 1.8 meters per second. An olympic runner ran the 200-meter dash in 21.3 seconds. How much faster was the runner’s speed than the swimmer’s speed to the nearest tenth of a meter per second?
Answer:
7.6m/s
Step-by-step explanation:
Find the time the Olympian swam
Speed=distance/time ⇒⇒Time=distance/speed
Distance=200m , speed= 1.8m/s t= 200/1.8 = 111.11 seconds
Find the speed of the Olympic runner
Distance=200m time = 21.3 sec
s=200/21.3 = 9.4 m/s
Difference in speed= 9.4-1.8= 7.6m/s
Answer:
7.6 m/s faster
Step-by-step explanation:
Speed of swimmer = 1.8 meters per second
The distance covered by runner = 200
Time of runner = 21.3 sec
We have to find the speed of the runner first so that we can compare with the speed of swimmer.
Speed = Distance/Time
=> 200/21.3
=> 9.4 m/s
So we have to find the difference between both speeds
Difference = 9.4 - 1.8
=> 7.6 m/s
So the runner was 7.6 m/s faster..

Answer:
Adults are given =
2n oranges
2n+n=once given
so
Step-by-step explanation:
The algebraic expression for the number of oranges given to adults in a group with an equal number of adults and children, with a specified distribution of oranges and a remainder, is 2A, where A represents the number of adults (or children, since they are equal).
Explanation:The question requires us to find an algebraic expression for the number of oranges given to the adults in a group where there are an equal number of adults and children, and a specific distribution of oranges to adults and children with a remainder.
Let's denote the number of adults by A, and thus, the number of children will also be A since the group has an equal number of adults and children. If n oranges are distributed, and each adult receives 2 oranges, then the total number of oranges given to adults is 2A. Each child receives one orange, so the number of oranges given to children is A. Including the 5 oranges that are left, the equation representing the total number of oranges is: 2A (for adults) + A (for children) + 5 (leftover) = n (total oranges).
From this equation, if you want to isolate the expression that represents the number of oranges given to adults, it is simply 2A.

a triangle has a base of 7m and a hypotenuse of 25m what is the area
Answer:
84 m²
Step-by-step explanation:
If you mention "hypotenuse," I automatically assume that this is a right triangle. We can find the length of the third side using the Pythagorean Theorem: 7² + x² = 25², or x² = 625 - 49 = 576.
Then the 3rd side (which is also the height of the triangle) is x = √576 = 24.
The base of this triangle is 7 m and the height is 24 m.
The area is thus:
A = (1/2)(base)(height) = (1/2)(7 m)(24 m) = 84 m²

A bag contains six red marbles three blue marbles and five green marble the three marbles are drawn out of the bag what is the probability to the nearest one hundredth that all three marbles will be drawn red?
Answer:
Step-by-step explanation:
Red = 6
Blue = 3
Green = 5
Total = 14
First marble = 6/14 = 3/7 You now have 5 reds and 13 total
Second Marble = 5 * 13 which brings you down to 4 red and 12 total.
Third Marble = 4/12 = 1/3
Result
P(3 Red) = 3/7 * 5/13 * 1/3 cancel the 3s
P(3 Red) = 1/7 * 5/13
P(3 Red) = 5/91
P(3 Red) = 0.0549 . Rounding to the nearest 1/100 depends on what you have been told about rounding. I would say the answer is 0.05 but your teacher may say something different.

A store is having a sale on walnuts and chocolate chips. For 3 pounds of walnuts and 2 pounds of chocolate chips, the total cost is $13. For 8 pounds of walnuts and 4 pounds of chocolate chips, the total cost is $33. Find the cost for each pound of walnuts and each pound of chocolate chips .
Final answer:
By setting up and solving a system of linear equations, we find that walnuts cost $3.50 per pound and chocolate chips cost $1.25 per pound.
Explanation:
The question involves using a system of two linear equations to find the cost per pound of walnuts and chocolate chips. We can define w to be the cost of one pound of walnuts and c to be the cost of one pound of chocolate chips. From the information given, we can set up the following two equations:
3w + 2c = 13
8w + 4c = 33
To solve these equations, we can use either substitution or elimination. Let's use elimination:
Multiply the first equation by 2 to align the coefficients of c. This gives us: 6w + 4c = 26.
Now, subtract the newly obtained equation from the second one: (8w + 4c) - (6w + 4c) = 33 - 26, which simplifies to 2w = 7.
Divide both sides by 2 to find w: w = 7/2, so w = $3.50 per pound for walnuts.
Substitute the value of w back into the first equation: 3(3.50) + 2c = 13. Therefore, 10.50 + 2c = 13.
Subtract 10.50 from both sides to find c: 2c = 2.50.
Divide both sides by 2 to get: c = 2.50 / 2, so c = $1.25 per pound for chocolate chips.
Therefore, walnuts cost $3.50 per pound and chocolate chips cost $1.25 per pound.
