The coordinate plane shows Line A B.
What is the length of the line segment?
Answer:
13
Step-by-step explanation:
The length of the line segment is 13 unit.
What is a line segment?A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).
If the ray lies onto the considered line segment(overlapping), then it can be said belonging to the considered line segment.
(line segment has 2 fixed ends, whereas a ray has one end only, other end is not fixed)
We are given that coordinate plane shows Line A B.
We need to find the length of the line segment.
We can see that the graph has 1 unit equal to 1 cm.
Then the coordinate for Point B is (5, 13)
The length of the line segment is 13 unit.

Which of the points shown below are on the line given by the equation Y = X +3? Check all that apply. A). Point A : (-1, 2) B). Point B : (-1, -2) C). Point C : (2, 5) D). Point D : (-3, 0) Please No jokes I really need help :))
Answer:
Point APoint CPoint DStep-by-step explanation:
The points are in the format (x , y) so given x which is the first figure, you can find y by following the formula.
Y in the point needs to satisfy the criterion of X + 3.
Point A
x = -1
y = x + 3
= -1 + 3
y = 2
Point A satisfies the equation as y from the equation is y in the point given.
Point B
x = -1
y = x + 3
= -1 + 3
y = 2
Point B does not satisfy the equation and so is not on the line.
Point C
x = 2
y = 2 + 3
y = 5
Point C satisfies the equation as y from the equation is y in the point given.
Point D
x = -3
y = -3 + 3
y = 0
Point D satisfies the equation as y from the equation is y in the point given.

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 9N acts on a certain object, the acceleration of the object is 3 m/s2 . If the force is changed to 6N , what will be the acceleration of the object?
Answer:
The acceleration is 2m/s^2
Step-by-step explanation:
Given
Variation: Direction Variation
Represent Force with F and Acceleration with A
When
[tex]F= 9N; A=3m/s^2[/tex]
Required
Find A when F =6N
The variation can be represented as:
[tex]F \alpha A[/tex]
Convert to an equation
[tex]F = kA[/tex]
Where
[tex]k = variation\ constant[/tex]
When
[tex]F= 9N; A=3m/s^2[/tex]
We have:
[tex]9N = k * 3m/s^2[/tex]
Solve or k
[tex]k = \frac{9N}{3m/s^2}[/tex]
[tex]k = 3kg[/tex]
When
[tex]F = 6N[/tex]
We have:
[tex]F = kA[/tex]
Substitute 6N for F and 3kg for k
[tex]6N = 3kg * A[/tex]
Solve for A
[tex]A = \frac{6N}{3kg}[/tex]
[tex]A = 2m/s^2[/tex]

What is the solution to the system of equations?
y = 2x + 6
y= x+ 2
A. (0,0)
C. (-2,-4)
B. (-4,-2)
D. (3,6)
Answer:
B
Step-by-step explanation:
Given the 2 equations
y = 2x + 6 → (1)
y = x + 2 → (2)
Substitute y = 2x + 6 into (2)
2x + 6 = x + 2 ( subtract x from both sides )
x + 6 = 2 ( subtract 6 from both sides )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (2)
y = - 4 + 2 = - 2
solution is (- 4, - 2 ) → B

Please help me :(, I want to understand how to prove it
Answer:
We know that angels 5 and 6 are vertical angles, and that vertical angles are equal. We also know that angles 7 is equal to angle 6, in turn meaning that angle 7 is also equal to angle 5. Now we look at angle 8. We can see that angle 8 is vertical to angle 7, meaning its also equal to angle 7. We already established before that angle 7 is equal to angle 5, so if angle 8 is equal to angle 7 which is equal to angle 5. Then angle 8 is equal to angle 5.

Suppose there is a 1.8 Farenheit drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 62.4 farenheit , what will be the temperature when the plane reaches an altitude of 8,000 ft. ?
Answer:
48° FStep-by-step explanation:
Let the altitude on the ground be 0 ft
Temperature at 8000 ft is:
62.4 - 1.8°*(8000 - 0)/1000 = 62.4 - 1.8*8 =62.4 - 14.4 =48° FAnswer:

Answer:
What is the question
Step-by-step explanation:
One winter day, the temperature outside was 13°F. Overnight, the temperature dropped 9°F. What is the temperature at its coldest point? Describe how you would find your answer on a number line.
Answer:
the coldest point would be 4 degrees.
Step-by-step explanation:
On a nuber line you would plot the point 13 and go back on the number line 9 units and you would get 4 degrees.
The temperature at its coldest point is 4° F.
Given that, one winter day, the temperature outside was 13°F. Overnight, the temperature dropped 9°F.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the temperature at its coldest point be x.
Now, x = 13 - 9
= 4° F
Therefore, the temperature at its coldest point is 4° F.

Pamela is making pizzas. She has 112 pieces of pepperoni. She uses 29 pieces of pepperoni on the first pizza. If she uses the same amount on each pizza, does she have enough pepperoni to make 4 more pizzas?
Answer:
No
Step-by-step explanation:
Number of pieces of pepperoni available with Pamela = 112
Number of pieces of pepperoni used in one pizza = 29
Now, number of pepperoni left after using 29 in one pizza = 112 - 29 = 83
Now, Pamela makes second pizza, so again 29 pieces of pepperoni area used.
Now, number of pepperoni left after using 29 in one pizza = 83 - 29 = 54
Now, Pamela makes third pizza, so again 29 pieces of pepperoni area used.
Now, number of pepperoni left after using 29 in one pizza = 54 - 29 = 25
To make the third pizza, another 29 pepperoni are required but only 25 are available.
Therefore, there is not enough pepperoni for making 4 more pizza.
What is X?[tex]\frac{x-2}{3} = \frac{-7}{18}[/tex]
Answer:
x = 5/6
Step-by-step explanation:
Cross multiply.
18(x - 2) = 3(-7)
Divide both sides by 3.
6(x - 2) = -7
Distribute the 6.
6x - 12 = -7
Add 12 to both sides.
6x = 5
Divide both sides by 6.
x = 5/6
Answer: x = 5/6
[tex]\dashrightarrow\:\:\sf \dfrac{x - 2}{3} = \dfrac{-7}{18} \\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf (x - 2) \times 18= -7 \times 3 \\ \\ \\ [/tex]

Explain how to estimate the quotient using compatible numbers.
27 2/3 divided by 3 9/10
Answer:
~7
Step-by-step explanation:
We can estimate 27 2/3 to be 28 because it is only 1/3 away from a whole number. Similarly, we can estimate 3 9/10 to be 4 because it is only 1/10 away from a whole number. Dividing the two, we get:
(27 2/3)/(3 9/10) = ~28/4 = ~7
We can estimate that the quotient of (27 2/3)/(3 9/10) will be about 7.
