What is an equation of the line that passes through the points -6, -2 and 6,-2
Answer:
y = 2
Step-by-step explanation:
m = (2 - 2)/(6 - (-6))
m = 0
there's no slope, so it's just 2
As you can see the 2 points have the same y coordinate that means the line passing through it is going to be a horizontal line with a consistent y level of -2.
The equation will be just what I said y=2

A ceramic vase that cost an antique store $7 was marked $63. What is the percentage markup on the price of the ceramic vase?
A-56%
B-900%
C-800%
D-44%
9514 1404 393
Answer:
C) 800%
Step-by-step explanation:
The markup amount is the difference between the selling price and the cost:
markup = selling price - cost
markup = $63 -7 = $56
The percentage markup relative to the cost is ...
markup/cost × 100%
= ($56)/($7) × 100%
= 8×100% = 800%

Answer:
1,330.5 cm³
Step-by-step explanation:
Volume of cylinder = πr²h
Where,
r = ½ of 11 = 5.5
h = 14 cm
Plug in the values
Volume = π × 5.5² × 14
Volume = π × 423.5
Volume = 1,330.5 cm³ (1 d.p)

• Demand equation: 0.7x + y = 340
Supply equation: -1.5x + y = 320
1. Solve the system algebraically to determine the balance point between
supply and demand.
Answer:
Step-by-step explanation:
Subtract equation 2 from equation 1
.7x+y-(-1.5x+y)=340-320
.7x+y+1.5x-y=20
2.2x=20
x=100/11, then use this in either original equation to find y.
.7(100/11)+y=340
y=3670/11, so the balance point is
(100/11, 3670/11)

In ΔPQR, what is the m∠Q? Enter your answer in the box.
m∠Q=
Answer:
105
Step-by-step explanation:
all of the angles added will add up to equal 180 so we setup the equation
180=11x-5+6x+5+x and solve
step 1 combine like terms
180=18x
step 2
divide each side by 18
x=10
then we just plug in 10 to 11x-5
11x10=110-5=105
angle q=105

Kathy was packing lunches for her 5 kids. She put the same items in each lunch box. She then decided to add 2 Oreos to each box. All together, she put 30 items in the lunch boxes. Which equation represents this situation?
Answer:
30/5-2 = number of items in each lunch box before adding the 2 Oreos.
Step-by-step explanation:
30/5=6 items in each box
6-2 Oreos=4 item besides the Oreos
30/5-2 = number of items in each lunch box before adding the 2 Oreos.

Jackson’s car was making a rumbling noise for two weeks. He decided to take it to the mechanic to get it checked out. To diagnose the problem, the mechanic tells Jackson that he charges a flat fee of $60 and $35 for each hour he spends trying to identify the problem.
A. Write a linear equation in y = mx+b form to represent the cost of getting Jackson’s car diagnosed.
B. Identify the slope and y-intercept, and what they mean in the context of the story.
C. Does this situation represent a proportional relationship? Why or why not?
Answer:
y=35x+60
slope-35 y intercept-60
proportional relationship
Step-by-step explanation:
Answer:
Step-by-step explanation:
y = 35x + 60
Slobe 35
y-intercept 60
The y-intercept is the start cost and the slope is how much it will go up per hour.
It is proportional because it is going up by 35 every hour

Which of the following two-dimensional shapes can be rotated to create a sphere?
A. Triangle
B. Square
C. Circle
D. Ellipse
please give an explanation and not just a letter or answer. Thank you.
The shape that can be rotated to create a sphere is the circle (option C).
A sphere is a three-dimensional object with all points equidistant from its center. When a circle is rotated about its center axis, it creates a three-dimensional shape that perfectly matches the definition of a sphere.
Let's consider the other options and why they cannot be rotated to form a sphere:
A. Triangle: A triangle is a two-dimensional shape with straight sides. Rotating a triangle around any axis would not result in a three-dimensional shape with all points equidistant from its center, which is the defining characteristic of a sphere.
B. Square: Similarly, a square is a two-dimensional shape with straight sides. Rotating a square around any axis would not create a sphere, as it would still retain its flat, planar nature.
D. Ellipse: An ellipse is a two-dimensional shape resembling a squashed or stretched circle. Rotating an ellipse would not result in a sphere, as it would still retain its elliptical shape.
Therefore, the shape that can be rotated to create a sphere is the circle (option C) due to its symmetrical and curved nature.

The set of ordered pairs below is a relation. {(0.5,2), (1.5,5), (4.0,12), (6.5,15)} Which relation has the same domain as the given relation?
{(1,5),(2,2),(-3,15),(-8,12)}
{(0.5,1),(1.5,4),(4.0,11),(6.5,14)}
{(2,1,1),(5,2.2),(12,3.3),(15,4.4)}
{(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)}
Given:
The set of ordered pairs is
{(0.5,2), (1.5,5), (4.0,12), (6.5,15)}
To find:
Which relation has the same domain as the given relation?
Solution:
We know that, domain is the set of input values or x-values.
For the given set {(0.5,2), (1.5,5), (4.0,12), (6.5,15)}, the domain is
Domain={0.5, 1.5, 4.0, 6.5}
Similarly,
For {(1,5),(2,2),(-3,15),(-8,12)},
Domain = {1, 2, -3,-8}
For {(0.5,1),(1.5,4),(4.0,11),(6.5,14)},
Domain={0.5, 1.5, 4.0, 6.5}
For {(2,1,1),(5,2.2),(12,3.3),(15,4.4)},
Domain = {2, 5, 12, 15}
For {(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)},
Domain = {-1, -3, -6, -10}
So, the relation {(0.5,1),(1.5,4),(4.0,11),(6.5,14)} has the same domain as the given relation.
Therefore, the correct option is B.
