Select all tables that represent a proportional relationship between X and Y
Answer:
The 'constant of proportionality k' DOES NOT remain constant for all the points in the table.
Therefore, the table DOES NOT represent a proportional relationship between X and Y.
Step-by-step explanation:
We know that when y varies directly with x, we get
y ∝ x
y = kx
k = y/x
where k is called the 'constant of proportionality'.
Given the table
x 0 5 10 15
y 2 17 32 47
Let us calculate the k value for all the points
FOR (0, 2)
k = y/x
substitute x = 0, and y = 2
k = 2 / 0 = ∞
FOR (5, 17)
k = y/x
substitute x = 5, and y = 17
k = 17/5
k = 3.4
FOR (10, 32)
k = y/x
substitute x = 10, and y = 32
k = 32/10
k = 16/5
k = 3.2
FOR (15, 47)
k = y/x
substitute x = 15, and y = 47
k = 47/15
k = 3.1
It is clear that the 'constant of proportionality k' DOES NOT remain constant for all the points in the table.
Therefore, the table DOES NOT represent a proportional relationship between X and Y.

Answer:
[tex]P > 300[/tex]
Step-by-step explanation:
Given
An art sold for over $300
Required
Represent as an inequality
Represent the price with p.
This implies that; P is over 300
In inequalities; the term "over" means greater than i.e. >
Hence:

Line a passed through points (-2,1) and (2,9). Which is parallel to line a?
Answer:
D
Step-by-step explanation:
Line A's slope: 9-1/2+2 = 8/4 = 2
y = 2x+b
y = 2x-5
If the slope of 2 lines are equal, then the lines are parallel.

Answer:
JML=142 degrees
Step-by-step explanation:
This shape is a rhombus, as all 4 sides are equal, but the angle measures are not. One of the properties of a rhombus is that opposite angles are congruent, and adjacent angles are supplementary. Only the second one is important. Since angles KLM and angle JML are supplementary, the equation KLM+JML=180 can be used. KLM is then substituted by the given angle measure, 38 degrees, to get an equation such as JML+38=180. Now, to solve for JML, 38 must be subtracted from both sides of the equation, which leaves teh answer of JML=142.
How are angle 4 and angle 5 related?
Answer:
C supplementary angles

The price of a notebook was $3.60 yesterday. Today, the price fell to $3.10. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answer:
13.9%
Step-by-step explanation:
First, we find the amount of decrease.
$3.60 - $3.10 = $0.50
The price decreased $0.50.
Now we find what percent $0.50 is of $3.60.
percent = part/whole * 100%
percent = $0.50/$3.60 * 100%
percent = 0.13888 * 100% = 13.9%
Answer: 13.9%
If a proportional relationship has a constant of proportionality of 6, what is a point that lies on the graph of
the line representing the relationship?
Answer:
(0,0) (1,6) (2,12)
Step-by-step explanation:
Proportional relationships are also known as direct variation, so I'll refer to it as DV.
The formula for finding DV is y=kx.
In this case, k=6, which is just y=6x. So, essentially..
(0,0) (1,6) (2,12) etc.
The points that lies on the graph of the line representing the relationship are (0, 0), (1, 60, and (2, 12).
What is Constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
As, we know that the constant proportionality have
y= k x
where k is constant of proportionality.
We have given that constant of proportionality = 6
So, y= 6x
Now, when x=0
y=0
and, x=1
y= 6
and, x=2
y= 12
Hence, the points are (0, 0), (1, 60, and (2, 12).

Answer: 35. The equation would be y = 17/2x
Answer:
32) yes, linear
33) no
34) yes
Step-by-step explanation:
32) if you look at the difference in the y-values and the difference of the x-values you will see that they all equal 3; for example, 24/8, 21/7, 18/6
33) following same method as for #32, there is not a consistent ratio of change between x-and-y values
34) yes, constant ratio is 10

What is the measure of x?
Answer:
x = 145
Step-by-step explanation:
x and 35 are adjacent angles and are supplementary, sum to 180° , then
x + 35 = 180 ( subtract 35 from both sides )
x = 145
Given the circumference of a circle is 8π centimeters, calculate the area of the circle in terms of π.
Answer:
16π cm²
Step-by-step explanation:
circumference = 2πr
Area = πr²
We need to determine r to calculate the area
2πr = 8π
Divide both sides of the equation by 2π to find r
r = 4
Now, we determine area.
area = πr² = π4² = 16πcm²
Answer:
[tex]\Large\boxed{\sf{16\pi\text{cm}^2}}[/tex]Step-by-step explanation:
The formula for the circumference of a circle can be used to solve this problem.
[tex]\underline{\text{CIRCLE OF A CIRCUMFERENCE FORMULA:}}[/tex]
[tex]:\Longrightarrow: \sf{C=2\pi r}[/tex]
[tex]\text{AREA:}= \sf{\pi r^2}[/tex]
[tex]\sf{2\pi r=8 \pi}[/tex]
You have to divide by 2 from both sides.
[tex]\sf{\dfrac{2\pi r }{2}=\dfrac{8\pi}{2} }[/tex]
Solve.
Divde the numbers from left to right.
8/2=4
r=4
[tex]\sf{\pi r^2=\pi4^2}[/tex]
Solve by exponents.
[tex]\sf{4^2=4*4=\boxed{\sf{16}}[/tex]
[tex]\Longrightarrow: \boxed{\sf{16\pi \text{cm}^2}}[/tex]
Therefore, the correct answer is 16πcm².I hope this helps. Let me know if you have any questions.

f(x)= (x-1)(x(x+1)+2x) find all rational zeros
Answer:
x = 0, x = 1, x = - 3
Step-by-step explanation:
To find the zeros, let f(x) = 0 , that is
(x - 1)(x(x + 1) + 2x) = 0 ← distribute and simplify parenthesis
(x - 1)(x² + x + 2x) = 0
(x - 1)(x² + 3x) = 0 ← factor out x from the second parenthesis
x(x - 1)(x + 3) = 0
Equate each factor to zero and solve for x
x = 0
x - 1 = 0 ⇒ x = 1
x + 3 = 0 ⇒ x = - 3
a + 3 + 2a = - 1 + 3a + 4 solve for A
