If L // M find the value of X. provide step by step explanation please
Answer:
x = 29°
Step-by-step explanation:
If line l is parallel to line m, therefore:
(180° - 130°) + 101° + x° = 180° (angles on a straight line)
50° + 101° + x° = 180°
151° + x° = 180°
x = 180° - 151° (substraction property of equality)
x = 29°
rectangle j is 6 feet wide and 9 feet long rectangle K is 9 feet wide and 12 feet long are the rectangle similar explain
Answer:
NO, they are not similar.
Step-by-step explanation:
Width of rectangle J = 6 ft
Length of rectangle J = 9 ft
Width of rectangle K = 9 ft
Length of rectangle K = 12 ft
Find the ratio of their corresponding dimensions:
Ratio of their width = 6/9 = 2/3
Ratio of the length = 9/12 = 3/4
Their ratio of their corresponding dimensions are not equal. That is, their corresponding dimensions are not proportional to each other. Therefore, they are not similar.

An economics professor gave her class two tests. 25% of the class passed both tests, and 48% of the class passed the first test. What percent of those who passed the first test also passed the second test? (Round to four decimal places)
9514 1404 393
Answer:
52.0833%
Step-by-step explanation:
The conditional probability formula applies.
P(2|1) = P(2&1)/P(1)
P(2|1) = 0.25/0.48 ≈ 0.520833
About 52.0833% of those who passed the first test also passed the second.

Comment on wording
As a fraction rounded to 4 decimal places, the value would be 0.5208 or 52.08%. This seems to ask for the percentage to be rounded to 4 decimal places, so it is 52.0833%.
For f (x) = 3x +1 and g(x) = x2 - 6, find (ff + g)(x).
Given:
The two functions are
[tex]f(x)=3x+1[/tex]
[tex]g(x)=x^2-6[/tex]
To find:
The function (f+g)(x).
Solution:
We know that,
[tex](f+g)(x)=f(x)+g(x)[/tex]
Putting the values of given functions, we get
[tex](f+g)(x)=3x+1+x^2-6[/tex]
[tex](f+g)(x)=x^2+3x+(1-6)[/tex]
[tex](f+g)(x)=x^2+3x-5[/tex]
Therefore, the required function is [tex](f+g)(x)=x^2+3x-5[/tex].

Step-by-step explanation:
for this, all you need to do is plug 8 into x for the equation y=8-2x
y=8-2(8)
y=8-16
y=-8
The value of y when x = 8 is,
⇒ y = - 8
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The table shows ordered pairs of the function as,
⇒ y = 8 - 2x
Now, At x = 8
The value of y is,
⇒ y = 8 - 2x
⇒ y = 8 - 2 × 8
⇒ y = 8 - 16
⇒ y = - 8
Thus, The value of y when x = 8 is,
⇒ y = - 8

which of the following best describes the quadratic function below ?
A. a parent function
B. an inverse function
C. opens right
D. opens down
Option A is correct, a parent function best describes the quadratic function.
The quadratic function with a vertex at the origin and opening upward is best described as a parent function.
A parent function is the most basic form of a particular type of function.
In the case of quadratic functions, the parent function is f(x) = x².
It has a vertex at the origin (0, 0) and opens upward.
