The required measure for the supplementary angles EB is calculated as 126°.
Given that,
Two supplementary angles are given ZA and ZB.
ZA = 2x - 20 ; ZB = 3x + 15
To determine the measure of ZB.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The sum of the supplementary angle is 180°.
ZA + ZB = 180°
2x - 20 + 3x + 15 = 180
5x - 5 = 180
5x = 180 + 5
5x = 185
x = 37
Now,
the measure of angle,
ZB = 3x + 15
ZB = 3 * 37 + 15
ZB = 126°
Thus, the required measure of the angle EB is 126°.

Answer:
-5, 1/2, -0.45, -0.05 would be the solution
Solve for w.
0.43 +2.7w = 3.7w - 0.47
Answer:
w = 0.9
Step-by-step explanation:
What I did is I subtracted 2.7 from 3.7 bc it was the least number and that gave me 1 so that left me with 0.43 = w - 0.47. Then I added 0.47 to 0.43 and that gives me 0.9 which would be the answer

We need to know about the difference between relation and function to solve this problem. Options 1 and 3 are functions but 2 and 4 are just relation not functions.
A relation is a relationship between two or more sets of values. A function is an expression that defines the relationship between two variables. The main difference between a relation and a function is that a relation can have multiple output for a single input but a function only has single output for a single input. Every function is a relation but every relation is not a function. In this question x is the input variable and y is the output variable,for option (1) all the input values have single output values, for option (2) the value x=0 has two different output values so this relation is not a function, for option (3) all input values have single output values, so it is a function and for option (4) the input value x=2 has two different output values so it is not a function.
Therefore we found out that options (1) and (3) are functions and the rest are just relations.

Which graph is the graph of the function [tex]g(x)=\frac{x^{2}-x }{x^{2} -1}[/tex]
see screenshot for answer choices
Answer:
A function is a mathematical relation that maps a value in a set of input numbers to a value in a set of output numbers. Some functions can map multiple values in one set to one value in the other set.
Step-by-step explanation:
For the function f(x)=∛2x , find f⁻¹(x) . Then determine the value of x when f(x)=16 .
The value of [tex]f^{-1}(x)[/tex] is [tex]\frac{x}{\sqrt[3]{2} }[/tex] when f(x) = 16 is [tex]x=2^\frac{11}{3}[/tex] .
An inverse function or anti -function is defined as a function that can be inverted into another function. Simply put, if the function 'f' makes x into y, the inverse of 'f' makes y into x. Where a function is denoted by 'f' or 'F', the inverse is denoted by f^-1.A function accepts values, performs some operation on those values, and produces an output. The inverse function works in line with the result and returns to the original function.An inverse function returns the original value that the functionWe have given a function [tex]f(x)=x\sqrt[3]{2}[/tex]. ....(1)
Let y = f(x)
[tex]y=x\sqrt[3]{2} \\\\x=\frac{y}{\sqrt[3]{2} }[/tex] ......(2)
Swap the values of x and y, then the inverse is then
[tex]y=\frac{x}{\sqrt[3]{2} }[/tex]
[tex]f^{-1}(x)=y[/tex] ...(3)
Comparing equation (2) and (3) , we get
[tex]f^{-1}(x)=\frac{x}{\sqrt[3]{2} }[/tex]
It is given that f(x) = 16 on comparing it with equation (1) , we get
[tex]x\sqrt[3]{2}=16\\x=\frac{2^4}{2^\frac{1}{3} } \\x=2^{4-\frac{1}{3} }\\x=2^\frac{11}{3}[/tex]

describe some possible random variables (other than the ones mentioned previously) and discuss whether they are continuous random variables or discrete random variables.
Random variables can be either discrete or continuous.
Sample spaces need not consist of numbers. In statistics, we are most often interested in numerical outcomes such as the "count" of an occurrence. We call X a random variable because its values vary when the phenomenon is repeated. We use capital letters near the end of the alphabet like X or Y.
A random variable is a variable whose value is a numerical outcome of a random phenomenon. When a random variable describes a random phenomenon the sample space S just lists the possible values of the random variable. There are two ways of assigning probabilities to the values of a random variable that will dominate our application of probability as we study statistical inference.
Random variables can be either discrete or continuous. A discrete random variable X has a "countable number of possible values. The probability distribution of X lists the values and their probabilities in table form. The probabilities must satisfy two requirements:
1) every probability pi is a number between 0 and 1
2) p1 + p2 +,,,+pk = 1.
The probability of any event is found by adding the probabilities pi of the particular values xi that makes up the event.

The equation of the line perpendicular to the given line and that passes through the point is x + 3y = 6
From the question, we are to determine the equation of the line that is perpendicular to the given equation.
A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line.
That is,
If m₁ is the slope of one of the lines
and m₂ is the slope of the other line
Then,
m₁ = -1/m₂
First, we will determine the slope of the given line
The equation of the given line is
y = 3x - 9
Compare the equation to the general form of the equation of a straight line
y = mx + b
Where m is the slope
and b is the y-intercept
By comparison,
m = 3
∴ The slope of the given line is 3
Thus,
The slope of the line that is perpendicular to this line is -1/3
Now,
To determine the equation this line,
We have that the line passes through the point (3, 1)
Using the point-slope form of the equation of a straight line,
y - y₁ = m(x - x₁)
m = -1/3
x₁ = 3
y₁ = 1
Putting the parameters into the equation,
y - 1 = -1/3(x - 3)
Expressing the equation in standard form
3(y -1) = -1(x - 3)
3y - 3 = -x + 3
3y + x = 3 + 3
x + 3y = 6
Hence, the equation of the line perpendicular to the given line and that passes through the point is x + 3y = 6

An inverse function or anti -function is defined as a function that can be inverted into another function. Simply put, if the function 'f' makes x into y, the inverse of 'f' makes y into x. Where a function is denoted by 'f' or 'F', the inverse is denoted by f-1 or F-1.A function accepts values, performs some operation on those values, and produces an output. The inverse function works in line with the result and returns to the original function.An inverse function returns the original value that the function provided the output for.We have given a function [tex]f(x)=\frac{2x^2}{5} +1[/tex]. ....(1)
Let y = f(x)
