===============================================================
Explanation:
Choice a) can be ruled out because angles A and D are supplementary. Supplementary angles add to 180 degrees by definition. They form a straight line or straight angle.
Choice b) and choice d) are eliminated for similar reasoning as choice a).
Choice c) is the only thing left. It turns out that angles B and D are not supplementary, but rather they are vertical angles. They are opposite one another in this X shape. Vertical angles are always congruent.
Note: Angles B and D are supplementary if and only if the angles are 90 degrees each.

Alex ate 4 less the 2 times the slices of pizza that Oliver ate.If Oliver ate 8 slices of pizza how many slices did alex eat?
Answer: 12
Step-by-step explanation: 2 times of 8 is 16, but it says 4 less, so you subtract 4 and that equals 12.

Divide both sides by 7:
[tex]\displaystyle \large{\dfrac{7x}{7}=\dfrac{1}{7}}\\\displaystyle \large{x=\dfrac{1}{7}}[/tex]
Therefore, the solution is x = 1/7
Answer:
[tex]x =\frac{1}{7}[/tex]
Step-by-step explanation:
Find the value of x in 7x = 1
[tex]7x = 1 < == divide\ both\ sides\ by\ 7\\\\\frac{7x}{7}=\frac{1}{7}\\\\ x =\frac{1}{7}[/tex]

The value of a motorcycle each year follows the sequence $12,000 $9,600, $7,680, $6,144
Which formula represents the recursive definition of the sequence where n represents the number of years?
The recursive definition of the geometric sequence is given by:
A. [tex]a_n = (0.8)a_{n-1}[/tex]
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The basic recursive relation is given as follows:
[tex]a_n = qa_{n-1}[/tex]
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem, considering the given sequence, the common ratio is given by:
[tex]q = \frac{6144}{7680} = \frac{7680}{9600} = \frac{9600}{12000} = 0.8[/tex]
Hence option A is correct.

The values of the motorcycle follows a geometric sequence
The recursive definition of the sequence is (a) [tex]a_{n} = 0.8a_{n-1[/tex]
How to determine the recursive definition?The values are given as:
$12,000 $9,600, $7,680, $6,144
Calculate the common ratio using:
r = a2/a1
So, we have:
r = 9600/12000
Divide
r = 0.8
Recall that:
r = a2/a1
So, we have:
a2/a1 = 0.8
Multiply both sides by a1
a2 = 0.8a1
Rewrite as:
[tex]a_{2} = 0.8a_{2-1[/tex]
Substitute n for 2
[tex]a_{n} = 0.8a_{n-1[/tex]
Hence, the recursive definition of the sequence is (a) [tex]a_{n} = 0.8a_{n-1[/tex]

I think of a number . If I subtract six from it and multiply the difference by 4 the result is 36. Evaluate the number that I thought of.
Answer:
15
Step-by-step explanation:
First we can make an equation by replacing the unknown number with x :
First step of problem:
x-6
Second part of problem:
4(x-6)
Third part of the problem:
4(x-6)=36
First we can expand the bracket to give us:
4x-24=36
Now we add 24 to both sides:
4x = 60
Now we divide both sides by 4 for our final answer of
x= 15
To check this answer we can put it back into the problem:
4(15-6)=36
4(9)=36
✅
Therefore our answer that was thought was 15.
You find another case with a sale price of $4.68 after a 40% discount. What is the original price of the case?
Answer:
11.7
Step-by-step explanation:
Since we know what the price was after the discount, we just have to reverse it. In order to apply a discount to a price, you multiply the number by the discount. e.g, 0.40 * x = 4.68. So to find the original price, we have to do the opposite. The opposite of multiplication is division, so divide 4.68 by 0.40, (0.40 is equivalent to 40%.) and we get 11.7.
11.7 is the original price.

Evaluate the function it at x = -1 and x = 5.
P(x)=
x²+2 if x <4
2x+10 if x >4
Answer:
f(-1) = 3
f(5) = 20
Step-by-step explanation:
When evaluating a piecewise-defined function, the first step is to locate the argument value in the correct domain. Then the corresponding function is evaluated in the usual way.
__
For x=-1, the relevant piece is the one defined for x < 4:
f(x) = x² +2
f(-1) = (-1)² +2 = 3
__
For x=5, the relevant piece is the one defined for x > 4:
f(x) = 2x +10
f(5) = 2(5) +10 = 20

The function written in this problem statement is "undefined" at x=4, so the graph would ordinarily show a "hole" there. We're not sure whether that is intentional.
which is 5,291, written in scientific notation?
Answer:
5.291 x 10⁶
Step-by-step explanation:
Why is 5,291,000 written as 5.291 x 106 in scientific notation?
The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.
Calculating scientific notation for a positive integer is simple, as it always follows this notation:
a x 10b
Follow the steps below to see how 5,291,000 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 5,291,000
New Number: 5.291000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 5 . 2 9 1 0 0 0
Decimal Count: 1 2 3 4 5 6
There are 6 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 5.291 (Please notice any zeroes on the end have been removed)
b = 6
Now the whole thing:
5.291 x 10⁶
Step 4
Check your work:
10⁶ = 1,000,000 x 5.291 = 5,291,000

Step-by-step explanation:
6. The total comment after the song released =5000
Then, the next day comment add up by 1500
Thus, (1500/5000) × 100
=30% of increase
7. 15.5-10.75 =4.75
(4.75/15.5 )×100= 30%
So, the decrease is -30%( If its about increase then its a positive number, but if its decrease just add a '-')
Answer:
See below ↓↓
Step-by-step explanation:
6.
% increase = Total - Original / Original5000 + 1500 - 5000 / 50001500 / 50000.330% increase8.

Answer:
Step-by-step explanation:
If an angle measures x degrees, the measure of its supplement is (180-x) degrees.
This means that x-62.4 = 180-x, meaning that x=121.2.
So, the angles are 121.2 and 58.8 degrees.

Answer:
Range of x: [tex]0\leq x < 12[/tex] or [tex]0\leq x\leq 11[/tex]
Largest possible value of [tex]x[/tex] is 19
Mean mark = 11.41 (nearest hundredth)
Step-by-step explanation:
The mode is the number that appears the most, so if the mode is 10, [tex]x[/tex] has to be smaller than 10.
We can say this in two ways:
[tex]0\leq x < 12[/tex] or [tex]0\leq x\leq 11[/tex]
since the number of points and players are positive integers.
The median is the middle value when the values in the data set are placed in order from smallest to largest.
If 10 is the median mark, to find the maximum number of 15s, sum the number of players scoring 5 and 10 points and subtract 1:
8 + 11 = 19
Therefore, the largest possible value of [tex]x[/tex] is 19.
The mean is the total of the numbers divided by how many numbers there are.
To find the total marks, multiply the number of points by the number of players, and sum (using x = 19):
[tex]\textsf{Total points}=5 \times 8+10\times12+15 \times 19=445[/tex]
Total number of players = 8 + 12 + 19 = 39
[tex]\textsf{mean mark}=\dfrac{445}{39}=11.41\:\textsf{(nearest hundredth)}[/tex]
