Answer:
(-2,3) or x= -2 and y= 3
Step-by-step explanation:
I didn't graph this, but you could.
For the first equation: Subtract x from both sides to get 2y= -x +4
Next divide both sides by 2 to get y= -1/2x + 2 (Now graph this)
For the second equation subtracted both sides by -3x to get 2y= -3x
Next, divide both sides by 2 to get y= -3/2x (Now graph this)
I used elimination. I wrote both equations out then subtracted 2y from both of them then did -2x = 4
x= -2
then I substitued -2 + 2y = 4
6 = 2y
y=3

A hypothesis test involves a comparison of which two elements?
a. Research results from a sample and a hypothesis about a population
b. Research results from a population and a hypothesis about a sample
c. Research results from a population and a hypothesis about the population
d. Research results from a sample and a hypothesis about the sample
Answer:
I believe its A, correct me if i'm wrong.
Step-by-step explanation:
A hypothesis test involves a comparison between research results from a sample and a hypothesis about a population.
Thus, option (A) is correct.
In hypothesis testing, a researcher starts with a null hypothesis, which represents the assumption of no difference or no effect in the population.
The researcher collects data from a sample and performs statistical analysis to determine whether the evidence supports or rejects the null hypothesis in favor of an alternative hypothesis.
The research results obtained from the sample are compared to the hypothesis about the population to determine whether there is enough evidence to reject the null hypothesis and accept the alternative hypothesis.

What are the three types of loops that can be built using the while statement and other statements?
The three types of loops that can be built using the while statement and other statements are The While Loop,The For Loop,The Do-While Loop.
What is loop?Loop in math is a path or line that starts and ends at the same point. It can refer to a continuous curve, like a circle, or to a sequence of discrete points, like a polygonal line. It is a fundamental concept in mathematics, used to study various topics such as curves, surfaces, and solids. Loops are also used in graph theory to study networks.
1. The While Loop: This allows you to execute a set of instructions until a certain condition is met.
2. The For Loop: This is a pre-defined loop that is used to iterate through a list of elements and execute a set of instructions for each element.
3. The Do-While Loop: This is similar to the While Loop, but the set of instructions are executed at least once before the condition is checked. This allows for a set of instructions to always be executed at least once.

If polygons are similar then what do you know about the corresponding sides and the corresponding angles?​
If two polygons are similar, it means that their corresponding angles are congruent (have the same measure) and their corresponding side lengths are in proportion to each other.
Similar polygons are two polygons that have the same shape but differ in size. Similar polygons have congruent congruent angles and proportional proportionate sides.
When two polygons are similar, their respective angles are congruent (have the same measure) and their corresponding side lengths are proportional to one another.
Additionally, the ratio of the length of any corresponding side of the two polygons is equal to the ratio of the length of any other corresponding side.

Answer:
B) y = -2/3x -2
Step-by-step explanation:
The equation is y = mx + b
m = the slope
b = y-intercept
The slope = rise/run
Let's pick 2 points (-3,0) (0, -2); we see the y decrease by 2 and the x increase by 3, so the slope is
m = -2/3 = -2/3
The Y-intercept is located at (0, -2)

How do you write end behavior?
The end behavior of a function is the way the graph of the function behaves as either x→∞ or x→−∞.
To calculate the end behavior of a function, we take the highest degree of the function and look at the leading coefficient. If the leading coefficient is positive, then the graph will go to positive infinity as x→∞ and will go to negative infinity as x→−∞. If the leading coefficient is negative, then the graph will go to negative infinity as x→∞ and will go to positive infinity as x→−∞. For example, if the function is f(x) = 2x^3 + 6x, then the highest power is 3 and the leading coefficient is 2, which is positive. Therefore, the graph of the function will go to positive infinity as x→∞ and will go to negative infinity as x→−∞.

What is the relationship between heart rate and oxygen consumption during exercise?
During exercise, there was a substantial link between heart rate, coronary flow, and cardiac oxygen consumption. As heart rate increases, so does oxygen consumption, which seems to reach a maximum at very fast heart rates.
Your pulse and heart rate both serve as indicators of how your heart is working. Your heart rate is the number of times it beats in a minute. Your arteries widen as a result of the number of times your heart beats every minute.
In healthy people, heart rate, workload, and oxygen consumption are all linearly connected up to a certain point. The heart's reaction to physical exercise or stress is considered to be controlled by the sympathetic nervous system.

Is the triangle with sides 25 cm 5 cm and 24 cm a right angle triangle?
The triangle formed by sides 24, 25 and 5 cm is not a right angled triangle.
What is Pythagoras Theorem ?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.
A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Is it possible to form a triangle whose sides are 3.5 cm 4.5 cm 7.5 cm long?
Yes, it is possible to form a triangle with sides of 3.5cm, 4.5cm, and 7.5cm. This is because these triangle's sides adhere to the triangle inequality theorem.
The triangle inequality theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. This is because in order to form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side, otherwise it would be impossible to connect the three sides and form a closed shape.
In this case,
3.5 cm + 4.5 cm = 8 cm > 7.5 cm
3.5 cm + 7.5 cm = 11 cm > 4.5 cm
4.5 cm + 7.5 cm = 12 cm > 3.5 cm
