Either Table A or Table B shows a proportional relationship.
Table A
x −2 −1 0 1
y 2 3 0 5
Table B
x −1 0 1 2
y −3 0 3 6
Plot the points from the table that shows a proportional relationship.
Answer:
the answer is table B
Step-by-step explanation:
Answer:
Table B shows a proportional relationship
Explanation:
In a proportional relationship two quantities vary directly with each other.
So,
y ∝ x
y = kx
Where, k is the constant of variation.
The ordered pairs of table A are (-2,2), (-1,3), (0,0) and (1,5).
From these ordered pairs we can conclude that the value of y-coordinate is not changing according to the x-coordinate because the values of x increased by 1 for each ordered pair but the value of y is not increasing in the same proportion..
The ordered pairs of table B are (-1,-3), (0,0), (1,3) and (2,6). The value of y increasing at a constant rate 3 and the value of y-coordinate is 3 times of x-coordinate.
Choose any two ordered pairs of table B. Let the two points are (0,0) and (1,3).
The proportional relationship is defined as
y = 3x
Therefore, 3 is the constant of variation and rate of change.
So, Table B shows a proportional relationship.

Part A: State the Greatest Common Factor of 12x2y5z and 150x6y5z and 66y9z
Show all work you did to determine the GCF.
Part B: Factor completely 4x2 – 20x +100
Part C: Factor completely. 81x2-64
Part D: State the factoring rule for special cases. (a + b)2 = ??
Part E: State the factoring rule for difference of two squares. a2 – b2 = ??
Answer:
Step-by-step explanation:
A) 12x² y⁵z = 2² * 3 * x² * y⁵ * z
150x⁶y⁵z = 5² * 2 * 3 * x⁶ * y⁵ * z
66y⁹z = 2 * 3 * 11 * y⁹ * z
GCF = 2 * 3 * y⁵ * z = 6y⁵z
B) 4x² - 40x + 100 = (2x)² - 2 * 2x * 10 + 10²
= (2x - 10)²
C) 81x² - 64 = (9x)² - 8² {a² - b² = (a + b)(a - b)}
= (9x + 8)(9x - 8)
D) (a + b)² = a²+ 2ab + b²
E) a² - b² = (a + b)(a - b)
Answer:
Simplifying 4x2y + 12xy2 + 9y3 Reorder the terms: 12xy2 + 4x2y + 9y3 Factor out the Greatest Common Factor (GCF), 'y'. y(12xy + 4x2 + 9y2) Factor a trinomial.

Whats the absolute value of 5/6?
Answer:
the absolute value of 5/6 is 5/6
Step-by-step explanation:
absolute value is just the distance from zero on a number line, so it just makes whatever number under the | x | the same number but positive.
Answer:
5/6 is the same you dont change it unless its negative
Step-by-step explanation:
If the fraction is positive, it is its own absolute value. If the fraction is negative, remove the negative sign. That is the absolute value. In other words, the absolute value of 1/7 is 1/7, and the absolute value of -5/8 is 5/8.

Which statement is true about the graphs of the two lines y=-x+2 and y=-x- ?
O The lines are perpendicular to each other because - and - are opposite reciprocals of each other.
The lines are perpendicular to each other because 2 and - 1 are opposite reciprocals of each other.
O The lines are neither parallel nor perpendicular to each other because - and are not opposite reciprocals
of each other.
The lines are neither parallel nor perpendicular to each other because 2 and - 3 are not opposite reciprocals of
each other.
Answer:
The correct option is Option C
Step-by-step explanation:
We are given the lines: [tex]y=-\frac{4}{5}x+2 \ and \ \ y=-\frac{5}{4}x-\frac{1}{2}[/tex]
The lines are perpendicular if they have opposite slopes i,e [tex]m_1=-\frac{1}{m_2}[/tex]
In line 1 the slope is [tex]-\frac{4}{5}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-4/5)
In line 2 the slope is [tex]-\frac{5}{4}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-5/4)
The opposite reciprocal of -4/5 is 5/4
So, the lines are not perpendicular as their slopes are not opposite reciprocal of each other.
If the lines are parallel there slope must be same. Hence lines are not parallel as well.
So, The correct option is Option C

Step-by-step explanation:
Closely pay attention to the transversal line running from up-left to down-right.
y) you will notice that the angle to the right of z is corresponding with 50 then 50 will be vertically opposite 6y + 2 hence making them equal.
6y - 2 = 50
6y = 50 - 2
6y = 48
y = 6
z) vertically opposite angles are equal hence the 50 will be equal to the empty space in the triangle.
z + 60 + 50 = 180
z + 110 = 180
z = 180 - 110
z = 70
2y + 3z
2(6) + 3(70)
12 + 210
= 222

Miguel wants to have at least $500 in his account to spend over the summer. He already has $150. If he deposits $25 each week, write and solve an inequality to determine how many weeks it will take him to reach at least $500.
Answer:
listen to the other guy
or girl
Step-by-step explanation:
It will take at least 14 weeks to have at least $500.
What is inequality?The relation between two unequal expressions is defined as inequality.
Given that, the person has $150 in his account and he deposits $25 each week into this account.
The amount in the account after w weeks is:
150 + 25w
Let the amount in the account after w weeks is at least $500, then it follows:
150 + 25w ≥ 500
25w ≥ 500 - 150
25w ≥ 350
w ≥ 14
Hence, it will take at least 14 weeks to have at least $500.
