a.9 and 15
GCD(9,15)=3
9 and 15 are not relatively prime.
b.9 and 40
GCD(9,40)=1
Hence, 9 and 40 are relatively prime.
c.9 and 21
GCD(9,21)=3
9 and 21 are not relatively prime.
d.15 and 21
GCD(15,21)=3
15 and 21 are not relatively prime.

Answer:
-1 + 6 = -7
Step-by-step explanation:
you go from -1 add 6 to the left and land on -7
because a - plus a - = a positive
you need to use a positive 6 to get a -7
what is the greatest common factor of 35+14
Answer:
7
Step-by-step explanation:
When you multiply two numbers together to get a product, those two numbers are considered factors of the product. There are certain operations in math that require comparing two or more numbers and identifying the largest factor they have in common. This is called the greatest common factor (GCF).
Answer:
The first step to find the gcf of 14 and 35 is to list the factors of each number. The factors of 14 are 1, 2, 7 and 14. The factors of 35 are 1, 5, 7 and 35. So, the Greatest Common Factor for these numbers is 7 because it divides all them without a remainder.
so 7 is the greatest common factor of 35+14
The factors of 14 are 1,2,7,14; The factors of 35 are 1,5,7,35.
"how may I apply the distributive property to this expression."
By factoring out 7, the expression 35+14 = 7(5 + 2) and so you have an alternative way of computing the sum.
49 = 7(7).
Which set of ordered pairs represents a function? \{(2, 9), (5, 9), (1, -6), (-5, 5)\}{(2,9),(5,9),(1,−6),(−5,5)} \{(6, 6), (6, 8), (-8, -7), (-3, -8)\}{(6,6),(6,8),(−8,−7),(−3,−8)} \{(1, 8), (9, -3), (7, -4), (7, -6)\}{(1,8),(9,−3),(7,−4),(7,−6)} \{(-5, -1), (-3, -7), (-5, 3), (-7, -4)\}{(−5,−1),(−3,−7),(−5,3),(−7,−4)}
Given:
The set of ordered pairs.
To find:
Which set of ordered pairs represents a function?
Solution:
A set of ordered pairs represents a function, if there exist unique output value for each input value.
In option A,
{(2, 9), (5, 9), (1, -6), (-5, 5)}
It is a function because all input has unique outputs.
In option B,
{(6, 6), (6, 8), (-8, -7), (-3, -8)}
For x=6, there exist two outputs y=6 and y=8. So, it is not a function.
In option C,
{(1, 8), (9, -3), (7, -4), (7, -6)}
For x=7, there exist two outputs y=-4 and y=-6. So, it is not a function.
In option D,
{(-5, -1), (-3, -7), (-5, 3), (-7, -4)}
For x=-5, there exist two outputs y=-1 and y=3. So, it is not a function.
Therefore, the correct option is A.
From the given option, the set of ordered pairs that represents a function is {(2, 9), (5, 9), (1, -6), (-5, 5)\}
Ordered pair of a functionA coordinate is known to represents a function if all the domain values have a unique value in the codomain.
The x-coordinate point should not be repeated for the coordinate to be a function, otherwise it is not a function.
From the given option, the set of ordered pairs that represents a function is {(2, 9), (5, 9), (1, -6), (-5, 5)\}

solve 2x + 6 = x - 4
Answer:
x=-10
Step-by-step explanation:
Move like terms to the same side
2x+6-x=-4
x=-4-6
x=-10
2x+6=x-4
subtract x from both sides
x+6=4
subtract 6 from both sides
x=-10

answer of 5 1/2 - 3 5/8
Answer:
3
Step-by-step explanation:
5 1/2 = 5 × 2 + 1/2 = 11/2
3 5/8 = 3 × 8 + 5/8 = 29/8
Now,
5 1/2 - 3 5/8 = 11/2 - 29/8
11/2 - 29/8
11 × 8 - 29 × 2/8 × 2
88 - 58/10
30/10 = 3
Thus, 5 1/2 - 3 5/8 = 3

How many 5-digit personal identification numbers are possible if the number cannot contain a
zero?
Answer:
59049 digits
Step-by-step explanation:
Given
Digits = 0 to 9
Required
Determine number of 5 digit pins that must not contain 0
There are 10 digits.
Since the pin must not contain 0, there are 9 digits left to select from.
The question didn't state that a digit can not be repeated, so I'll assume that repetition of digit is allowed.
The 1st digit of the 5 could be any of the 9 digits
The 2nd could be any of the 9 digits
The 3rd could be any of the 9 digits
The 4th could be any of the 9 digits
The 5th could be any of the 9 digits
Hence, number of selection is calculated as this:
Selection = 9 * 9 * 9 * 9 * 9
Selection = 59049
Mr. Florean opened an account with deposit of $5,000. The account earned 7.5% annual simple interest. He did not make any additional deposits or withdrawals. After some time, the balance of the account was $6,500. How many years did it take for mr.Flores to have a balance of $6,500?
Answer:
4 years
Step-by-step explanation:
The simple interest = $6,500 - $5,000 = $1500
From the formula for simple interest;
I=PRT/100
T= 100 I/PR
T= 100 × 1500/5000 × 7.5
T= 150000/37500
T= 4 years

Answer:
1. Y = 2, 1, 4, 7, 10
2. Y = -12, -8, -4, 0, 4
3. Y = -7, -5, -3, -1, 1
Step-by-step explanation:
all of the numbers in the x value you just substitute in the x place in problem
1. Y = 3x + 4
x: -2, -1, 0, 1, 2
Y = 3(-2) + 4
Y = -6 + 4
Y = -2
You then have:
x: -2, -1, 0, 1, 2
y: -2,
Y = 3(-1) + 4
Y = -3 + 4
Y = 1
You then have:
x: -2, -1, 0, 1, 2
y: -2, 1
just continue substituting each x variable into the x place to get your y variable.
I know you asked for the first 6 but I feel like if I just give you the answers to all of them you will not learn it, so I only gave the first 3, and I recommend trying to do the last 3 yourself. I'm sure you'll do well. <3

Answer:
y = (-9/8)x + 7
Step-by-step explanation:
the line equation for slope intercert form looks like this
y = mx + b
m is the slope
b is the y intercept
The line intercepts the y at b= 7 (as noted in point (0, 7)
To find slope, use the 2 points given and the slope formula
m = (y2 - y1) / (x2-x1)
point (x1, y1) is (0, 7) and
point (x2, y2) is (8, -2)
plug in the correct spots for m = (y2 - y1) / (x2-x1)
m = (-2 - 7) / (8 - 0) = -9 / 8
substitute y = mx +b = (-9/8)x + 7
I hope this helps :-)
What is the slope of line ?
Answer:The slope is m= 1/2
