directed line segment from A to B such that Pis the
length of the line segment from A to B?
(2, -1)
(4, -3)
(-1,2)
(3,-2)
Answers
Answer:
answer b
Step-by-step explanation:
The coordinates of p are (3, -2). Option D is correct.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
From the graph, the coordinates of A = (9,-8) and the coordinates of B =(-6, 7) p divides the line segmentin 2/3 thus,
We can use the section formula to find the coordinates of the point P that divides the line segment AB into the ratio 2:3.
The section formula states that if a line segment AB is divided by a point P into two line segments, with lengths in the ratio m:n, then the coordinates of P are:
[tex][Px = (nA_x + mB_x)/(m+n), \\Py = (nA_y + mB_y)/(m+n)][/tex]
In this case, we want to divide the line segment AB into the ratio 2:3, so we have m:n = 2:3. This means that m = 2 and n = 3.
Substituting the given values, we get:
[tex]P_x = (3*9 + 2(-6))/(2+3) = 3\\Py = (3*(-8) + 2*7)/(2+3) = -2[/tex]
Therefore, the coordinates of P are (3, -2).

A pizza restaurant charges a flat fee for a plain cheese pizza. There is an extra charge for any additional toppings. The cost of a pizza can be I determined from the equation C = 0.5m + 5, where m is the number of
additional toppings and C is the cost of the pizza ordered. What are the
interpretations of slope and y-intercept in the equation?
A
slope: cost per additional topping
y-intercept: cost of the plain pizza
B. slope: cost per additional topping
y-intercept: cost of the first topping
C. slope: cost of the plain pizza
y-intercept: cost per additional topping
D. slope: ratio of cost of additional topping to the cost of the plain pizza
y-intercept: cost of an additional topping
Answers
The slope of 0.5 represents the cost per additional topping, while the y-intercept of 5 represents the cost of the plain pizza. Option A provides the correct interpretations.
To interpret the slope and y-intercept of the equation C = 0.5m + 5, where C represents the cost of the pizza and m represents the number of additional toppings:
A. The correct interpretation is:
- Slope: The slope of 0.5 represents the cost per additional topping. This means that for each additional topping added to the pizza, the cost increases by $0.5.
- Y-intercept: The y-intercept of 5 represents the cost of the plain pizza without any additional toppings. This is because when m = 0 (no additional toppings), the cost of the pizza is $5, which is the flat fee for the plain cheese pizza.
To confirm:
- When m = 0, the equation becomes C = 0.5(0) + 5 = 5 , which is the cost of the plain pizza without any additional toppings.
- When m = 1, the equation becomes C = 0.5(1) + 5 = 5.5, indicating that the cost increases by $0.5 when one additional topping is added.
Therefore, option A correctly interprets the slope and y-intercept of the equation.

Step-by-step explanation:
102 degrees- 3 degrees=
99 degrees.
Steve's temperature was 102º F when he woke up. Two hours later, his temperature had dropped by 3º F, thus making his temperature 99º F.
Explanation:The subject of this question is a real-life mathematics reasoning task about temperature change. Based on the given information, Steve's initial temperature when he woke up was 102º F.
According to the problem, Steve's temperature decreased by 3º after two hours.
To find Steve's temperature after the decrease, you simply have to subtract this decrease from the original temperature. So you calculate 102º F - 3º F, which equals 99º F. Therefore, Steve's temperature two hours later was 99º F.

Answer:
From left to right:
2, 4, 32
Step-by-step explanation:
Using the one column which is completed, determine the ratio of yellow to blue by reducing to lowest terms.
yellow to blue = 8 to 16
8 and 16 are both divisible by 8. 8/8 = 1 and 16/8 = 2
8 to 16 = 1 to 2
This means there is half as much yellow paint as there is blue paint. If said backwards, there is double the amount of blue paint as there is yellow paint.
In the first two columns, yellow paint is blue paint divided by 2.

#18 i can't figure this out
Answers
Answer:
∠Q = 75 °
Step-by-step explanation:
Since PR = PQ then Δ PQR is isosceles and the base angles are congruent, that is
∠R = ∠Q = 2x + 15
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
2x + 15 + 2x + 15 + x = 180, that is
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
Hence
∠Q = 2x + 15 = (2 × 30) + 15 = 60 + 15 = 75°

x/2 + 3 = -5
Answers
Answer:
The solution for the equation is x equal to -16
Step-by-step explanation:
Let's find the solution for x in the equation given:
x/2 + 3 = -5
Multiplying by 2 at both sides of the equation, we have:
x + 6 = -10
Subtracting 6 at both sides of the equation, we have:
x + 6 - 6 = - 10 - 6
x = - 16
The solution for the equation is x equal to -16
Terms used: multiply, subtract, solution, equal to, equation
To solve the equation x/2 + 3 = -5 for x, subtract 3 from both sides to get x/2 = -8. Then multiply both sides by 2 to isolate x, giving the solution x = -16.
Explanation:To find the solution for the variable x in the given equation x/2 + 3 = -5, we need to use the inverse operations of addition and division. Firstly, we need to eliminate the +3 from the left-hand side of the equation. We apply the inverse operation to addition which is subtraction. Therefore, we subtract 3 from both sides of the equation. This calculates to: x/2 = -5 -3. This can be simplified to x/2 = -8.
Secondly, to solve for the variable x we then need to remove the division by 2 and to do this, we multiply each side of the equation by 2 (the inverse operation of division) because x divided by 2 multiplied by 2 is equal to x. Hence the new equation becomes: 2*(x/2) = 2*-8 and simplifying gives us x = -16.
This process shows that the solution to the equation x/2 + 3 = -5 is x = -16.

Answers
Answer:15/28
Step-by-step explanation: Ive had this question before That is the answer :)
Final answer:
To find the probability of selecting a solid sock both times from Daniel's drawer, multiply the probabilities at each step independently to get 1/105 or approximately 1% in total.
Explanation:
To calculate the probability of selecting a solid sock both times, you need to consider the independent probabilities at each step.
Probability of selecting a solid sock the first time is 1/7.
Probability of selecting a match for the second sock from the remaining socks would be 1/5.
Continuing this pattern, the total probability of selecting a solid sock both times is 1/105 or about 1%.

The y int is 4
Write the equation in y = mx + b form
y = 4x + 4
A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 20 child bikes and 6 adult bikes in the week. (2 points) Group of answer choices No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Answer:
No, because the bike order does not meet the restrictions of 6c + 4a ≤ 100Step-by-step explanation:
It is given that, each child bike requires 4 hours to build and each adult bike requires 6 hours to build.
Hence, c child bikes and a adult bikes require [tex](4c + 6a)[/tex] hours to build.
It is also given that, each child bike requires 4 hours to test and each adult bike requires 4 hours to test.
Total time to test, c child bikes and a adult bikes is [tex](4c + 4a)[/tex]
The company will be able to make c child bikes and a adult bikes if [tex](4c + 6a) \leq 120\\(4c + 4a)\leq 100[/tex]
If c = 20 and a = 6, then (4c + 6a) = 116 < 120.
and (4c + 4a) = 104 > 100.
