Determine if the lines through each set of ordered pairs are parallel, perpendicular, or neither. Explain your answer. Ordered pairs: (8, 3) (-2, 5) and (-2, -5) (-1, -10)
The lines through each set of ordered pairs are neither parallel nor perpendicular.
How to determine the relationship?The ordered pairs are given as:
(8, 3) (-2, 5) and (-2, -5) (-1, -10)
Start by calculating the slope (m) using:
m = (y2 - y1)/(x2 - x1)
For the first pair, we have:
m = (5 - 3)/(-2 - 8)
m = -1/5
For the second pair, we have:
m = (-10 + 5)/(-1 + 2)
m = -5
Both slopes are not equal, so they are not parallel
Also, both slopes are not opposite reciprocals, so they are not perpendicular.
Hence, the lines through each set of ordered pairs are neither parallel nor perpendicular.

Step-by-step explanation:
30-60-90 Triangle Theorem
A special right-angled triangle where:
Angles are in the ratio 1 : 2 : 3Sides are in the ratio 1 : √3 : 2Therefore, the formula for the sides is b : b√3 : 2b where:
b = shortest side opposite the 30° angleb√3 = side opposite the 60° angle2b = longest side (hypotenuse) is opposite the right angleThe given triangle is a 30-60-90 triangle, therefore the ratio of its sides is b : b√3 : 2b
We have been given the measure of the side opposite the 60° angle.
⇒ b√3 = 6√3
So b = 6
Therefore, substituting the found value of b into the formula, the sides are in the ratio: 6 : 6√3 : 12
⇒ x = 6 (shortest side)
⇒ y = 12 (longest sides)

The graph below have the same shape.what is the equation of the blue graph?
Answer:
g(x) = (x - 5)²
Step-by-step explanation:
This is an example of the transformation of functions.
In this example, we see the graph f(x) has been moved 5 in the positive direction on the x-axis.
Due to the fact that we are working with the x-axis, our transformation will be placed inside the bracket, and it will do the opposite of what we expect.
This means that our transformation will be set out in this format:
[tex]g(x) = f(x-5)[/tex]
We know that:
[tex]f(x) = x^2[/tex]
Therefore,
[tex]g(x) = f(x-5) = (x-5)^2[/tex]
So, [tex]g(x) = (x-5)^2[/tex].

Answer: B -4
Step-by-step explanation: I think it is B because -4 is smaller than A,C and D.
The smallest integer among the options provided is option A, which is -84.
In the context of integers, smaller values are considered to be "less" than larger values.
In this case, we can compare the given integers to determine the smallest one.
Comparing the options:
A. -84
B. -4
C. 34
D. 24
Out of these options, -84 is the smallest integer because it has the lowest numerical value.
The negative sign indicates that it is a number less than zero, and the absolute value of 84 is greater than the absolute values of -4, 34, and 24.
Therefore, based on numerical value, -84 is the smallest integer among the options given.

Subtraction property of equality
====================================================
Explanation:
Let's say we started with the equation a = b
Subtract c from both sides to get a-c = b-c
This is the subtraction property of equality
-----------------
Example:
x+5 = 12
x+5-5 = 12-5 ... using the subtraction property of equality
x+0 = 7
x = 7
------------------
For this current problem, we're subtracting 3 from both sides in the second step.
A very closely related property is the addition property of equality where we add the same thing to both sides.
Technically we could add -3 to both sides to get the same task done in the second step. But the subtraction property is more direct and straight-forward in my opinion.
Given that h={A,E,I,O,U},which is the number of possible subsets of set h
There are 32 subsets of the set h.
We have given that h={A,E,I,O,U},
We should count the elements of the set, then put that number as the exponent of 2.
What is the subset?A set A is a subset of another set B if all elements of set A are elements of set B. In other words, set A is contained inside set B.
Remember that 2 should always be the base in finding the number of subsets: 2^5=32
Therefore there are 32 subsets of the set h.
Here set h is denoted by small h but the set is always denoted by capital letters.

Step-by-step explanation:
[tex]\frac{1-\frac{25}{k^2} }{1-\frac{7}{k}+\frac{10}{k^2} }[/tex]
multiply numerator and denominator by k² to eliminate fractions
= [tex]\frac{k^2-25}{k^2-7k+10}[/tex] ← factor numerator and denominator
------------------------------
k² - 25 ← is a difference of squares
= (k - 5)(k + 5)
k² - 7k + 10
= (k - 5)(k - 2)

Find the tables with unit rates greater than the unit rate in the graph then arrange these tables in order from least to greatest unit rate
Table 3,4,5,6,7 has a greater value of the unit rate than the unit rate of the graph.
What is a graph?A diagram depicting the relationship between two or more variables, each measured along with one of a pair of axes at right angles.
The unit rate of the graph is;

[tex]\rm r_2 = \frac{26-13}{14-7} \\\\ r_2 = \frac{9}{5} \\\\ r_2 = 1.8 < 1.818[/tex]
[tex]r_3 = \frac{34-17}{18-9} \\\\r_3 = \frac{17}{9} \\\\ r_3 = 1.889 > 1.818[/tex]
[tex]\rm r_4 = \frac{42-21}{22-11} \\\\ r_4 = \frac{21}{11} \\\\ r_4 = 1.909 > 1.818[/tex]

An equation in math is an equality relationship between two expressions written on both sides of the equal to sign.
Given:
(1/8)²-3y = [tex]2^{y}[/tex]-2
1/64 - 3y = [tex]2^{y}[/tex]-2

The probability that the coin lands on tails and the dice lands on an even number is 0.3455
How to determine the probability?Let A represents a biased coin lands on heads and B represents a biased dice lands on an even number
So, we have:
P(A) = 0.47
P(B) = 13/20
The required probability is:
P(A' and B) = P(A) * P(B)
