==============================================================
Explanation:
We have a pair of vertical angles. The angles do not need to align vertically to be considered vertical angles. They simply just need to be opposite one another in this X configuration as the diagram shows.
Vertical angles are always congruent.
Set the expressions equal to one another. Solve for x.
2x+15 = 145
2x = 145-15 ... subtracting 15 from both sides
2x = 130
x = 130/2 .... dividing both sides by 2
x = 65
Answer: 65
Step-by-step explanation:
2x + 15 = 145
2x + 15 - 15 = 145 - 15
2x = 130
2x/2 = 130/2
x = 65

A number line going from negative 7 to positive 1. Points are at negative 7 and positive 1.
Answers
Answer:
A number line going from negative 1 to positive 7. Points are at positive 1 and positive 7.
Step-by-step explanation:
We have the equation:
|8 - 2*p| = 6
Remember that the equation:
|f(x)| = A
with A > 0
means that:
f(x) = A
or
f(x) = -A
Then for our case, we can rewrite:
|8 - 2*p| = 6
as:
(8 - 2*p) = 6
or
(8 - 2*p) = -6
Now we can solve these two equations to find the two possible values of p.
From the first one, we get:
8 - 2*p = 6
8 - 6 = 2*p
2 = 2*p
2/2 = p = 1
so one solution is p = 1
Now from the other equation, we can get the other solution:
(8 -2*p) = -6
8 - 2*p = -6
8 + 6 = 2*p
14 = 2*p
14/2 = p = 7
So the two solutions are p = 1 and p = 7
Then the correct option is:
"A number line going from negative 1 to positive 7. Points are at positive 1 and positive 7."

Step-by-step explanation:
Given equation is 2t/(t-5) + 1/(t-3) = 3
=> [2t(t-3)+1(t-5)]/(t-5)(t-3) = 3
=> (2t²-6t+t-5)/(t²-5t-3t+15) = 3
=> (2t²-5t-5)/(t²-8t+15) = 3
=> 2t²-5t-5 = 3(t²-8t+15)
=> 2t²-5t-5 = 3t²-24t+45

Solve |3x-2|=8 algebraically. {Note: your text may refer to this method as the definition of absolute value, which is more commonly called the absolute value principal.} b) Verify your solution(s). c) Write your solution set { }:
Answers
The solution set is {10/3, -2}. To solve the equation |3x - 2| = 8, we can consider two cases: when the expression inside the absolute value is positive, and when it is negative.
Let's solve each case separately:
Case 1: 3x - 2 is positive (3x - 2 > 0):
Solving for x:
3x - 2 = 8
3x = 8 + 2
3x = 10
x = 10/3
Case 2: 3x - 2 is negative (3x - 2 < 0):
Solving for x:
-(3x - 2) = 8
-3x + 2 = 8
-3x = 8 - 2
-3x = 6
x = 6/(-3)
x = -2
Therefore, the solutions to the equation |3x - 2| = 8 are x = 10/3 and x = -2.
To verify these solutions, we substitute them back into the original equation:
For x = 10/3:
|3(10/3) - 2| = 8
|10 - 2| = 8
|8| = 8
8 = 8 (True)
For x = -2:
|3(-2) - 2| = 8
|-6 - 2| = 8
|-8| = 8
8 = 8 (True)
Both solutions satisfy the equation, so they are valid solutions.
The solution set is {10/3, -2}.

graphically, the solution to a system of two independent linear equations is usually
Answers
Graphically, the solution to a system of two independent linear equations is represented by the point of intersection of the two lines.
The solution to a system of two independent linear equations can be graphically represented as the point of intersection between the two lines.
When two linear equations are plotted on a graph, each of them will generate a straight line, and their solution is the point that satisfies both equations simultaneously. This point is represented by the intersection of the two lines.
If the two linear equations represent parallel lines, then there is no solution since the lines do not intersect. If the two linear equations represent the same line, then there are infinitely many solutions.
However, in the case where the two linear equations are independent, meaning they have different slopes, and different y-intercepts, they will intersect at a unique point that represents their solution. In other words, the point of intersection represents the ordered pair that satisfies both equations and is the solution to the system of equations.

Asx approaches negative infinity, for which of the following functions does f(x) approach positive infinity? Select all that apply. Select all that apply: f(x) =2x5 Ofx)9x +100 f(x)= 6x8 +9x6+32 f(x)=-8x3 + 11 f(x)=-10x +5x+ 26 f(x)=-x +8x4 + 248
Answers
Among the provided functions, the ones that approach positive infinity as x approaches negative infinity are:
- f(x) = 2x^5
- f(x) = 6x^8 + 9x^6 + 32
- f(x) = -x + 8x^4 + 248
To determine which functions approach positive infinity as x approaches negative infinity, we need to analyze the leading terms of the functions. The leading term dominates the behavior of the function as x becomes very large or very small.
Let's examine each function and identify their leading terms:
1. f(x) = 2x^5
The leading term is 2x^5, which has a positive coefficient and the highest power of x.
As x approaches negative infinity, this term becomes very large and positive, indicating that f(x) approaches positive infinity.
2. f(x) = 9x + 100
The leading term is 9x, which has a positive coefficient but a lower power of x compared to the constant term 100.
As x approaches negative infinity, the leading term becomes very large and negative, indicating that f(x) approaches negative infinity, not positive infinity.
3. f(x) = 6x^8 + 9x^6 + 32
The leading term is 6x^8, which has a positive coefficient and the highest power of x.
As x approaches negative infinity, this term becomes very large and positive, indicating that f(x) approaches positive infinity.
4. f(x) = -8x^3 + 11
The leading term is -8x^3, which has a negative coefficient and the highest power of x.
As x approaches negative infinity, this term becomes very large and negative, indicating that f(x) approaches negative infinity, not positive infinity.
5. f(x) = -10x + 5x + 26
Combining like terms, we have f(x) = -5x + 26.
The leading term is -5x, which has a negative coefficient but a lower power of x compared to the constant term 26.
As x approaches negative infinity, the leading term becomes very large and positive, indicating that f(x) approaches negative infinity, not positive infinity.
6. f(x) = -x + 8x^4 + 248
The leading term is 8x^4, which has a positive coefficient and the highest power of x.
As x approaches negative infinity, this term becomes very large and positive, indicating that f(x) approaches positive infinity.
Therefore, the correct choices are:
- f(x) = 2x^5
- f(x) = 6x^8 + 9x^6 + 32
- f(x) = -x + 8x^4 + 248

A. Yes
B. No, because F(x) is negative for some x
C. No, because F(x) exceeds one for some x
D. No, because the area under F(x) does not equal 1
Answers
As per the probability density function, a continuous random variable is option (d) No, because the area under F(x) does not equal 1
A probability density function (PDF) is a non-negative function that integrates to 1 over its support, which is the range of values that the random variable can take.
The function F(x) = x satisfies the non-negativity property because x is always non-negative in the given interval [0,10]. However, we need to check whether F(x) integrates to 1 over its support or not.
To find out if F(x) is a valid PDF, we need to integrate it over its support [0,10] and see if the result is equal to 1. Therefore,
integral from 0 to 10 of F(x) dx = integral from 0 to 10 of x dx
= 1/2x² from 0 to 10
= 1/2(10)² - 1/2*(0)²
= 50
Since the result of the integral is not equal to 1, we can conclude that F(x) is not a valid PDF. Therefore, the answer is (D) No, because the area under F(x) does not equal 1.

Aisha has dd dimes and qq quarters. She has a maximum of 23 coins altogether. Write this situation as an inequality
Answers
Aisha has a maximum of 23 coins altogether which is equal to dd dimes plus qq quarters. This can be written as an inequality as dd + qq ≤ 23.
Aisha has a maximum of 23 coins altogether, which consists of a certain number of dimes (denoted as dd) and quarters (denoted as qq). Since the maximum number of coins Aisha can have is 23, this can be expressed as an inequality, dd + qq ≤ 23. This inequality states that the total number of dimes and quarters Aisha has must be less than or equal to 23. To solve this equation, we can use a trial and error method, where we make reasonable assumptions for the number of dimes and quarters Aisha has and see if the sum of them is less than or equal to 23. If it is, then our assumptions are correct, otherwise we need to make new assumptions. For example, if we assume that Aisha has 7 dimes and 11 quarters, then 7 + 11 = 18, which is less than 23, so our guess is correct. However, if we assume that Aisha has 8 dimes and 12 quarters, then 8 + 12 = 20, which is greater than 23, so our guess is incorrect. As we can see, this method can be used to solve any inequality, as long as we make reasonable assumptions for the variables.
