Which is the line shown in the figure?
line XY
line XZ
line WX
line WZ
Option B is the correct answer.
We need to check which is the line shown in the figure.
What is a line?In geometry, a line is an infinitely long object with no width, depth, or curvature. Thus, lines are one-dimensional objects, though they may exist in two, three, or higher-dimension spaces. The word line may also refer to a line segment in everyday life, which have two points to denote its ends.
Now, from the given figure we can see XZ is a line.
Therefore, option B is the correct answer.

Al drives from Boston to Washington D.C. and then returns. On his trip to Washington, he travels 60 miles per hour. On his return trip, he travels 50 miles per hour. His trip to Boston takes an hour and a half longer than his trip to Washington. How far apart are Washington and Boston? Make a equation
The distance apart from Washington and Boston is 450 miles.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
We have,
Trip from Boston to Washington:
Speed (2) = 60 miles per hour
Trip from Washington to Boston:
Speed (1) = 50 miles per hour
Speed = Distance / Time
Time = Distance / Speed
Distance is the same for both trips.
Time taken for the trip from Washington to Boston = t(1)
Time taken for the trip from Boston to Washington = t(2)
His trip to Boston takes an hour and a half longer than his trip to Washington.
This can be written as,
t(1) - t(2) = 1.5 hours
Distance ( 1/50 - 1/60) = 1.5
Distance ( (6 - 5)/300 ) = 1.5
Distance (1 / 300) = 1.5
Distance = 1.5 x 300
Distance = 450 miles
Thus,
The distance apart from Washington and Boston is 450 miles.

What is the standard form of the equation of a parabola that opens left or right
Answer:
The equation of the parabola which opens left or right is [tex]x=ay^2+by+c[/tex].
Step-by-step explanation:
We know that,
If in the equation of the parabola,
1. If x is squared, then the parabola opens upwards or downwards.
2. If y is squared, then the parabola opens towards left or right.
Since, we want the equation of the parabola which opens left or right.
So, we get that,
The variable 'y' is being squared in the equation of the given parabola (from 1).
Thus, the equation of the parabola which opens left or right is [tex]x=ay^2+by+c[/tex].Answer:

A drama club wants to raise at least $500 in tickets sales for its annual show. The members of the club sold 50 tickets at a special $5 rate. The usual ticket price the day of the show is $7.50. At least how many tickets do they have to sell the day of the show to meet the goal. Let t=tickets
To meet their fundraising goal, the drama club needs to sell 34 tickets at $7.50 each.
Answer:
The drama club wants to raise at least $500 in ticket sales. They already sold 50 tickets at $5 each. Let the number of tickets they need to sell at $7.50 be represented by 't'.
Revenue from $5 tickets: $5 × 50 = $250To find the number of $7.50 tickets needed: $500 - $250 = $250Number of $7.50 tickets needed: $250 / $7.50 = 33.33Therefore, the drama club needs to sell at least 34 tickets at $7.50 each to meet their goal.

The second train will catch up with the first train after 5/3 hours.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is a train that leaves a train station at 1 p.m. it travels at an average rate of 60 mi/hr. A high-speed train leaves the same station an hour later. it travels at an average rate of 96 mi/hr. The second train follows the same route as the first train on a track parallel to the first.
We have -
Assume that the second train catches the first in x hours. Then, we can write -
60(x + 1) = 96x
60x + 60 = 96x
96x - 60x = 60
36x = 60
x = 60/36
x = 5/3 hours
Therefore, the second train will catch up with the first train after 5/3 hours.

You and your friend are selling raffle tickets for a new laptop. you sell 14 more then your friend sells. Together you and your friend sell 58 tickets. Write a system of linear equations that represent this situation. How many did each of you sell?
You sold 36 tickets and your friend sold 22 tickets.
Explanation:Let's represent the number of tickets you sell as x and the number of tickets your friend sells as y.
We know that you sell 14 more tickets than your friend, so we have the equation:
x = y + 14
We also know that together you and your friend sell 58 tickets, so the equation becomes:
x + y = 58
Now we can solve these two equations simultaneously to find the values of x and y.
Substitute the value of x from the first equation into the second equation:(y + 14) + y = 58
Combine like terms:2y + 14 = 58
Subtract 14 from both sides to isolate the variable:2y = 44
Divide both sides by 2 to solve for y:y = 22
Now substitute the value of y back into one of the original equations to solve for x:x = 22 + 14
Simplify:x = 36
Therefore, you sold 36 tickets and your friend sold 22 tickets.

The system of equations representing the problem is y = x + 14 and x + y = 58. Solving this system we get x = 22 (friend's sold tickets) and y = 36 (your sold tickets).
Explanation:We'll use a system of linear equations to model this situation. Let's define x as the number of tickets your friend sells, and y as the number of tickets you sell. From the problem, we know two things:
1. You sell 14 more tickets than your friend: y = x + 14.
2. Together, you and your friend sell 58 tickets: x + y = 58.
To solve this system, we can substitute y in the second equation with x + 14 from the first equation. This gives us:
x + (x + 14) = 58.
Solving this we get x = 22 and substituting x into the first equation gives: y = 22 + 14 = 36.
So, your friend sold 22 tickets, and you sold 36 tickets.

Which graph represents the solution set for the system 6x + y > -3 and 2x + y ≤ 4?
A. graph A
B. graph B
C. graph C
D. graph D
Answer:
Option B. Graph B
Step-by-step explanation:
The given system of the inequalities are 6x + y > -3 and 2x + y ≤ 4
If we take the first inequality which represents the area below the line 6x + y = -3 or y = -6x - 3 (Slope of the line -6 and y-intercept is -3)
Second graph is represented by 2x + y ≤ 4 which represents the area below the line y = 4 - 2x ( slope = -2 and y intercept = 4)
Option B shows the shaded area which the common area representing the solution set of these systems.

system 1
2x - 2y =12
-2x-3y = -22
solve simultaneous equation
2x - 2y =12
-2x-3y = -22
add the equations gives

What value of n would make point A the circumcenter?
1. 2
2. 3
3. 4
4. 5
Answer:
The correct option is 2. The value of n is 3.
Step-by-step explanation:
Circumcenter is the point, where the perpendicular bisectors of a triangle intersect each other.
Circumcenter is also known as the center of the triangle. The distance from circumcenter to each vertex are same.
In triangle DEF, if A is the circumcenter.
[tex]AE=AD[/tex]
[tex]10=2n+4[/tex]
Subtract 4 from both sides.
[tex]10-4=2n[/tex]
[tex]6=2n[/tex]
Divide both sides by 2.
[tex]3=n[/tex]
Therefore the value of n is 3 and option 2 is correct.
Answer:
Option 2 is true
Step-by-step explanation:
We have to find the value of n for which point A becomes circumcenter.
Circumcenter: It is that point where perpendicular bisectors of triangle intersects.
The circumcenter is also knows as center of triangle.
Circumcenter is at equal distance from each vertex of triangle.
If point A is circumcenter then
AE=AD
We have AE=10 units
AD=2n+4
Substitute the value
10=2n+4
[tex]2n=10-4[/tex]
By subtraction property of equality
[tex]2n=6[/tex]
[tex]n=\frac{6}{2}=3[/tex]
Hence, the value of n is 3 would make point A the circumcenter.
