D. {(1, 2), (2, 3), (3, 4), (3,5)}
Answer:
A
Step-by-step explanation:
A function cannot have 2 points on the same x point, and so every coordinate on A's set is different (-1, 2, 8, 10)

How do you factor 1x^2+9x+2
Answer:
not factorable
Step-by-step explanation:
To factor a trinomial of the type x^2 + ax + b, you need to find two numbers that add to a and multiply to b.
You have 1x^2 + 9x + 2.
In this case, a = 9 and b = 2.
There are no two integers whose sum is 9 and whose product is 2, so this trinomial is not factorable.

A brick becomes dislodged from the top of the Empire State Building (at a height of 1250 feet) and falls to the sidewalk below. What is the position formula?
Answer:
Position s(t) = -16t² + 1250 ft
Step-by-step explanation:
Given that:
initial height h₀ = 1250 feet
and suppose the position function is given as:
-16t² + v₀t + h₀
here;
v₀ = initial velocity
t = time
Thus, the position formula can be expressed as:
Position s(t) = -16t² + 1250 ft because v₀ = 0 ft/s and h₀ = 1250 feet

What is the relationship between the slopes of two parallel lines?
Answer:In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other.
Step-by-step explanation:
The slopes of two parallel lines are always equal.
How to find the slope of a line?The slope of a line can be calculated by taking the tangent ratio of the angle formed by it with the x axis.
The angle between two parallel lines is zero.
It implies that they form same angle with the x-axis.
Since, the slope of a line is define as the tangent of the angle made by it with x axis.
The slopes of the parallel lines will be equal.
Suppose the slopes of two parallel lines are m₁ and m₂.
Then, it can be written as m₁ = m₂.
Hence, the relationship between the slopes of two parallel lines can be written as m₁ = m₂.

At a school, 60% of the sixth-grade students said that hip-hop is their favorite kind of music. If 210 sixth-grade students prefer hip hop music, how many sixth-grade students are at the school?
Answer:
350 6th grade students
Step-by-step explanation:
From the question
At a school, 60% of the sixth-grade students said that hip-hop is their favorite kind of music.
Total number of sixth graders that love hip-hop = 210
Let the total number of students in the school be represented as: x
Hence,
60% × x = 210
60/100 × x = 210
Cross Multiply
60x = 210 × 100
x = 210× 100/60
x = 350 students.
Therefore, the total number of sixth graders is 350 .

What is the original slope and what is the perpendicular slope?
Answer:
green line:
rise= -6
run= 3
rise/run = slope
therofore the slope = -6/3 = -2
blue line:
rise=3
run=6
rise/run = slope
therofore the slope = 3/6 = 1/2
Answer:
- 2 and [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 5) and (x₂, y₂ ) = (0, - 1) ← 2 points on the green line
m = [tex]\frac{-1-5}{0+3}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2
Repeat with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (6, 0) ← 2 points on the blue line
m = [tex]\frac{0+3}{6-0}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
Since the product of the slopes = - 2 × [tex]\frac{1}{2}[/tex] = - 1
Then the lines are perpendicular

The ratio of the number of marbles in the red bag to the number in the blue bag is 3 : 5
Two marbles are moved from the blue bag to the red bag, making the ratio 7 : 9.
How many marbles are there in total?
answer: 16
step by step explanation:
The total number of marbles = 32 marbles.
We have ratio of the number of marbles in the red bag to the number in the blue bag is 3 : 5. After that, two marbles are moved from the blue bag to the red bag, making the ratio 7 : 9.
We have to find out how many marbles are there in total.
Is the ratio a:b equal to [tex]\frac{a}{b}[/tex].Yes, a:b equals to [tex]\frac{a}{b}[/tex] - where ' a ' is called Antecedent and ' b ' is called Consequent.
Let the total number of marbles be x.
Let the number of marbles in the red bag be ' x ' and in blue bag ' y '.
According to question -
[tex]\frac{x}{y} =\frac{3}{5}[/tex]
5x = 3y
x = [tex]\frac{3y}{5}[/tex]
After the two marbles are moved from blue bag are moved into the red bag, then -
[tex]\frac{x+2}{y-2} =\frac{7}{9}[/tex]
9(x + 2) = 7(y - 2)
9x + 18 = 7y - 14
9x - 7y = -32
9 ([tex]\frac{3y}{5}[/tex]) - 7y = -32
[tex]\frac{27y}{5} - 7y =-32[/tex]
[tex]\frac{-8y}{5}=-32[/tex]
-8y = -32 x 5
y = 4 x 5
y = 20
Therefore -
x = [tex]\frac{3\times20}{5}[/tex] = 12
Hence, the total number of marbles = x + y = 20 + 12 = 32 marbles.

Twelve large bottles of water cost $9. How many bottles can you buy for $3? What is the cost per bottle of water? How much would 7 bottles of water cost?
Step-by-step explanation:
Given data
cost of 12 bottle = $9
How many bottle can $3 buy.
Given that $9 can buy 12 bottles
therefore $3 would by x bottles
cross multiply we have
9x=12*3
9x=36
divide both sides be 9
x=36/9
x=4 bottles
The cost per bottle is
9/12= $3/4
= $0.75 per bottle
if one bottle cost $0.75
the 7 bottles will cost =0.75*7
=$5.25
Answer:

A printer is printing photos. For every 6 photos, the printer takes 2 minutes.
Complete the table below showing the number of photos and the time it takes to print them.
Answer:
Next to 6 is 9, next to 15 is 27, and next to 3 is 5
Step-by-step explanation:
If you imagine 6 photos for every 2 minutes as a fraction and simplify it, the answer to this would be 3 photos for every 1 minute (basically 3/1). By using this unit fraction, you'll see that you're supposed multiply the amount of minutes by 3, or you can divide the # of photos by 3.
For 3 mins, you multiply that by 3 to get 9 photos.
For 9 mins, you multiply that by 3 to get 27 photos
For 15 photos, you divide that by 3 to get 5 photos.

A triangle has angle measures x + 15 , 3x − 35 , and 4x. Find the value of x
Using the knowledge of the total sum of the internal angles of a triangle, the value of x would be 25
Recall :
A + B + C = 180° (Sum of the internal angles of a triangle)Hence,
(x + 15) + (3x - 35) + 4x = 180
x + 15 + 3x - 35 + 4x = 180
8x - 20 = 180
8x = 180 + 20
8x = 200
x = 200 / 8
x = 25°
Therefore, the value of x is 25
