Explanation: you can identify the range or limit of this equation by either looking at the graph or understanding the equation logically.
Looking at the graph, you can see to the left of the Y axis, the graph is approaching but not touching Y = 0. This means that Y = 0 is a limit to this equation and that the graph will not cross this line.
Or we can think about it logically. If we keep multiplying by 2 over and over, a value will keep getting bigger to infinity. That's the right side of this graph. Then for x < 0, that represents dividing by 2 over and over. That value will only ever get smaller and smaller. But never reach zero. It's like folding a paper in half forever.

What is the slope of this line?

Answers
You can find the rise/run (slope) by finding the y-intercept on the graph (if it is on the graph which in this case it is the y-intercept is 5)
For example: if 3/4 was the slope then 3 would be the rise which means that you would move from the y-intercept upwards 3 points and 4 would be the run and would be move over to the right by 4 points. From the y-intercept you rise 3 points and run 4 points.
This graph is negative as noted by its downward direction meaning the slope will be negative.
To find the slope first find the y-intercept in this case y-intercept = 5.
Next find another solids point that also passes through the line, in this case this is point (1,3)
Move from the y-intercept (5) by -2 points or downwards by 2.
Then move over (run) by one point.
The -2 rises or in this case falls and the 1 goes to the right/runs
Insert these two numbers into the rise/run formula
-2/1 = -2
The answer is -2

The commutative property for addition just means the sum is the same no matter what order you add the terms. This property is also true for multiplication of real numbers.
If altering the operands' order has no effect on the outcome, the binary operation is commutative in mathematics. Numerous binary operations depend on it as a fundamental property, and numerous mathematical arguments.
A commutative property in mathematics states that if integer positions are switched around or combined while performing addition or multiplication operations, the result will remain the same.
According to the commutative property, the numbers we use can be moved around or swapped around without changing the solution. For addition and multiplication, the property is true, but not for division or subtraction.

Assume you have applied for two jobs a and b. The probability that you get an offer for job a is 0. 25. The probability of being offered job b is 0. 20. The probability of getting at least one of the jobs is 0. 40. What is the probability that you will be offered both jobs? enter your answer as a decimal rounded to two places.
Answers
If you have applied for two jobs a and b and the probability that you get an offer for the job a is 0.25 and the probability of being offered job b is 0.20, then the probability that you will be offered both jobs is 0.05.
Probability is that branch of mathematics that deals with the numerical description of the possibility of an event to occur. The probability of any event is a number between 0 and 1 where 0 represents the impossibility of the event to occur while 1 represents certainty of that event to occur.
As the probability of the job a and job b are independent of each other, the probability that both jobs will be offered can be determined by using the formula;
P(A∩B) = P(A) × P(B)
Here, P(A∩B) represents the probability of both the events happening together
As P(A) = 0.25
P(B) = 0.20
P(A∩B) = 0.25 × 0.20
P(A∩B) = 0.05
Hence, the probability that both jobs will be offered is calculated to be 0.05.

What is slope of a line segment ?
Slope is the ratio of the difference in y-coordinates over the equivalent x-coordinates between two different locations on a line.
It is given that the vertices of a triangle are P(-6,1), Q(-2,-5) and R(8,1).
a.
The midpoint (M) of QR will be equal to
( [tex]\frac{-2 + 8}{2} , \frac{-5 + 1}{2}[/tex] )
or
M = (-3 , 2)
Now , slope of line QR will be ;
[tex]m_{QR}[/tex] = [tex]\frac{1+5}{8+2}[/tex]
[tex]m_{QR}[/tex] = 6 / 10
We know that :
m × [tex]m_{QR}[/tex] = -1
m = -10 / 6
or
m = -5 / 3
Equation of line will be given as :
y + 2 = [tex]\frac{-5}{3}[/tex] ( x - 3 )
y = [tex]\frac{-5}{3}[/tex] x + 3
b.
The midpoint of PQ will be :
= ([tex]\frac{-6 - 2}{2} , \frac{1 - 5}{2}[/tex])
= ( -4 , -2)
The slope of median of triangle that passes through point R will be ;
m = [tex]\frac{-2 - 1}{-4-8}[/tex]
m = -3 / -12
m = 1/4
or
m = 0.25
c.
Slope of altitude of triangle that passes through point Q will be :
m = [tex]\frac{1 - 1}{-6-8}[/tex]
m = 0 / -14
m = 0
The slope in this case doesn't exist.
Therefore the answers will be :
a. The equation of perpendicular bisector of QR is y = [tex]\frac{-5}{3}[/tex] x + 3.
b. The slope of median of triangle passing through point R is 1/4.
c. The slope of the altitude of the triangle that passes through point R doesn't exists.

What is a rational number ?
If p & q are any two numbers where q is not equal to 0, then the fraction in form p/q is called as rational number.
A number is given which is √22.
√22 = 4.69041576
Let's check which of the statements are correct.
A.
√22 is not rational number as the number has non - terminating decimal value which is 4.69041576 and it doesn't lies between 10 and 12. So , this option is not correct.
B.
This option is also not correct as the value of √22 nearly equals 4.69 is and not greater than 4.691.
C.
The value of √22 is 4.69041576.
If we round off to the nearest hundredth , 9 is at the hundredth place , so the value will be 4.69. This is a correct option.
D.
√22 is not a rational number as the number has non - terminating decimal value which is 4.69041576 but it lies between 4 and 5. So , this option is not correct.
E.
The value of √22 is 4.69041576. We can observe that the decimal number doesn't repeat. So , this is a correct option.
F.
As we know √22 is not a rational number we can't represent it as fraction. This option is not correct.

Answers
The function that models the inverse variation is y = -56/x.
What exactly is the inverse variation?Inverse variation refers to a relationship between two variables in which the value of one increases while the value of the other decreases.When two quantities, say X and Y, are related in such a way that increasing X causes a decrease in Y and vice versa, this is known as indirect or inverse variation.So,
In an inverse function: x · y = C where C is the constant.Then,
-7 · 8 = -56 = CSince x · y = C then we obtain:
x · y = -56 ⇒ y = -56/xTherefore, the function that models the inverse variation is y = -56/x.
