Answer:
it is not a function
Step-by-step explanation:
if you can pass a vertical line through more than one point it is not a function, you have two points with the same x and different y
(-13,4) and (-13,9)
because you have two different y values for the same x it would fail the vertical line test and thus is not a function

Step-by-step explanation:
Answer:
2( x +2 )
x+1
Step-by-step explanation:
to add or subtract expressions expand them to make their denominators the same, multiply 1 time [tex]\frac{x-2}{x-2}[/tex]
since [tex]\frac{x}{x-2}[/tex] and [tex]\frac{x-2}{x-2}[/tex] have the same denominators add them by adding their numerators
combine x + x -2
factor [tex]x^{2}[/tex] - 4
to add or subtract expressions expand them and multiply by 1
have same denominator add them by adding their numerators
do the multiplications in 3 + ( x-2 )(x+2)
combine like terms in 3 + [tex]x^{2}[/tex] + 2x - 2x -4
divide [tex]\frac{2x-2}{x-2}[/tex] by [tex]\frac{-1 + x^{2} }{(x-2)(x+2) }[/tex] multiplying [tex]\frac{2x-2}{x-2}[/tex]
cancel out x-2 in both numerator and denominator
factor the expression that are not already factored
cancel out x-1 in both numerator and denominator

A golfer hit a golf ball from a tee box that is 6 yards above the ground. The graph shows the height in yards of the golf ball above the ground as a quadratic function of x, the horizontal distance in yards of the golf ball from the tee box. What is the domain of the function for this situation?
Answer: C. 0 ≤ x ≤ 230
When the A golfer hit a golf ball from a tee box that is 6 yards above the ground so the domain of the function is [0,260].
Calculation of the domain of the equation:Here the domain is the values of 'x' in the function f(x).
the position at which the golfer is hit the ball is (0,6) and the position where the ball hits the ground is (230,0)
So, the domain of the function for this situation is [0,260].

There are 1001 pennies lined up on a table. I come along and replace every 2nd coin with a Nickle. Then, replace every 3rd coin with a Dime. Finally, I replace every 4th coin with a Quarter. How much money is on the table?
Answer:
$99.19
Step-by-step explanation:
Problem:
On a table there are 1001 pennies lined up in a row. I come along and replace every second coin with a nickel. Then I replace every third coin with a dime. Finally, I replace every fourth coin with a quarter. How much money is on the table now? Why is twelve important?
Solution:
Our first step was to make a line of pennies (as long as possible) in order to see if we could figure out a pattern that would help us determine the total amount of money on the table.
Then we went through and replace every second coin with a nickel.
Then we went through and replaced every third coin with a dime.
Then we went through and replaced every fourth coin with a quarter.
As a group we then tried to decipher if there was a pattern that would help us determine the total value of coins. We then noticed that there was a pattern of twelve coins.
= $1.19
= $1.19
= $1.19
We determined the number of times the pattern of twelve coins repeated in the 1001 coins:
1001 ÷ 12 = 83 R5
Since we knew that the pattern repeated itself 83 full times and each time the dollar value is $1.19 we counted to determine the cost of the first 996 coins.
$1.19 X 83 = $98.77
Then we added the remaining 5 coins, which cost $0.42
$98.77 + $0.42 = $99.19
Therefore, there is a total of $99.19 on the table.
Since, the lowest common multiple of 2, 3, and 4 is 12, the pattern will repeat itself every 12th coin.
A sequence or pattern in a series of numbers is a number patterns
The amount of money in coins lined up on the table is $99.19
The reason the above value is correct is as follows:
The given parameters are;
The number of pennies lined up on a table = 1,001
The coin with which every second coin is replaced with = A Nickle = 5 Cents
The coin with which every third coin is replaced with = A Dime = 10 Cents
The coin with which every second coin is replaced with = A Quarter = 25 Cents
[tex]\begin{array}{ccc}Coin \ Position&&Coin \ Value \ (Cents)\\1&&1\\2&&5\\3&&10\\4&&25\\5&&1\\6&&10\\7&&1\\8&&25\\9&&10\\10&&5\\11&&1\\12&&25\\13&&1\\14&&5\\15&&10\\16&&25\\17&&1\\18&&10\\19&&1\\20&&25\\21&&10\\22&&5\\23&&1\\24&&25\end{array}[/tex]
From the above values, we have that the first twelve coins are repetitive, therefore, the number of repeating units is the whole number part of 1,001/12 = 83, which gives;
1 + 5 + 10 + 25 + 1 + 10 + 1 + 25+ 10 + 5 + 1 + 25 = 119
The value sum of the 83 repeating 12 units = 119 × 83 = 9877
The value of the first 12 × 83 = 996 coins = 9,877 Cents
The coin in the;
997th position = 1 Cent
998th position = 5 Cent
999th position = 10 Cent
1,000th position = 25 Cent
1,001th position = 1 Cent
The total value of the coins = (9,877 + 1 + 5 + 10 + 25 + 1) Cents = 9919 Cents
9919 Cents = $99.19
The amount of money that is on the table = $99.19

Thor and Rusty bought snacks for a party. Thor bought 4 bags of chips and 3 bottles of soda for $10.52. Rusty bought 3 bags of chips and 2 bottles of soda for $7.61. How much did the bags of chips each cost? How much did the bottles of soda each cost?
Answer:
Chips= $1.79
Soda= $1.12
Answer:
chips: $1.79
soda: $1.12
Step-by-step explanation:
x = chips cost
y = soda cost
4x + 3y = 10.52
3x + 2y = 7.61
i used the elimination method by multiplying the first equation by -2
and the second equation by 3
-8x - 6y = 21.04
9x + 6y = 22.83
x = 1.79
solve for 'y':
3(1.79) + 2y = 7.61
5.37 + 2y = 7.61
2y = 2.24
y = 1.12
Nasim is taking a multiple choice test with a total of 50 points available. Each

got 5 questions wrong? What would be his score if he got x questions wrong?
Score with 5 questions wrong:
Score with a questions wrong:
Pls help fast 80 points
Answer:
Score with 5 questions wrong = 40 points
x questions wrong = 50 - 2x points
Score with a question wrong = 48 points
Step-by-step explanation:
Total points = 50 points
Points per question = 2 points
Number of questions = Total points / Points per question
= 50/2
= 25 questions
What would be Nasim's test score (out of 50) if he got 5 questions wrong
= Total points - 5 questions * 2 points
= 50 - 5(2)
= 50 - 10
= 40 points
Score with 5 questions wrong = 40 points
What would be his score if he got x questions wrong?
= Total points - x questions * 2 points
= 50 - x(2)
= 50 - 2x
Where x = number of questions
x questions wrong = 50 - 2x points
Score with a question wrong
= Total points - 1 questions * 2 points
= 50 - 1(2)
= 50 - 2
= 48 points
Score with a question wrong = 48 points
