Two quanties are in a relationship if all of the ratios are
proportional.
For example, One way to see if two ratios are proportional is to write them as fractions and then reduce them.
12y=17-9x and -4y-3x=31 solve by elimination
Answer:
0 ≠ 110
No solution
Step-by-step explanation:
Solve by Addition/Elimination
12y = 17 − 9x and −4y − 3x = 31
Reorder 17 and −9x. 12y = −9x + 17
−4y − 3x = 31
Add 9x to both sides of the equation.
12y + 9x = 17
−4y − 3x = 31
Reorder the polynomial.
9x + 12y = 17
−4y − 3x = 31
Reorder the polynomial.
9x + 12y = 17
−3x − 4y = 31 9x + 12y = 17
Multiply each equation by the value that makes the coefficients of x opposite.
9x + 12y = 17
(3) ⋅ (−3x − 4y) = (3) (31)
Simplify (3) ⋅ (−3x − 4y).
Apply the distributive property.
9x + 12y = 17
3 (−3x) + 3 (−4y) = (3) (31)
Multiply −3 by 3. 9x + 12y = 17
−9x + 3 (−4y) = (3) (31)
Multiply −4 by 3. 9x + 12y = 17
−9x − 12y = (3) (31)
Multiply 3 by 31. 9x + 12y = 17
−9x − 12y = 93
Add the two equations together to eliminate x from the system.
9x+12y=17
+−9x−12y=93
0=110
Since 0 ≠ 110, there are no solutions. No solution

Jemma gave 0.30 of her candy to her sister and 0.25 of her candy to her brother. How much of her candy to her brother. How much of her candy did she give away.
So, Jemma gave away 0.30 percent and also gave 0.25 away all we have to do is add these two percents and we have our answer!
0.30% + 0.25% =
0.30 plus 0.25 equals to 0.0055 so you get your answer 0.0055!

Sydney accepted a new job at a company with a contract guaranteeing annual raises. Sydney's salary after working for n years can be determined using the equation S = 85000 + 1500n. What is the slope of the equation and what is its interpretation in the context of the problem?
Answer:1500 and the raise she will get each year
Step-by-step explanation:
Answer:
The slope of the function is 1500 which represents the raise that Sydney will get each year.
Step-by-step explanation:
The slope shows how much the salary increases each year, which is the same thing as saying that Sydney got a raise of $1500 every year.

{(y=7x+6),(4x-3y=16):}
Answer:
(−2, −8)
Step-by-step explanation:
Write the problem as a mathematical expression.
y = 7x + 6
4x − 3y = 16
Replace all occurrences of y in 4x − 3y = 16 with 7x + 6. 4x − 3 (7x + 6) = 16
y = 7x + 6
Simplify 4x − 3 (7x + 6).
−17x − 18 = 16
y = 7x + 6
Solve for x in the first equation.
Move all terms not containing x to the right side of the equation.
−17x = 34
y = 7x + 6
Divide each term by −17 and simplify.
x = −2
y = 7x + 6
Replace all occurrences of x with −2 in each equation.
Replace all occurrences of x in y = 7x + 6 with −2. y = 7 (−2) + 6
x = −2
Simplify 7 (−2) + 6.
y = −8
x = −2
The solution to the system is the complete set of ordered pairs that are valid solutions.
(−2, −8)
The result can be shown in multiple forms.

The sum of the digits of certain two-digit number is 9. Reversing its digits increase the number by 45. Find the number.
A) 36
B) 30
C) 27
D) 26
If the original number can be written as ab, where a is the digits in the tens place and b is in the ones place, then it can be expanded as
10a + b
where a and b are chosen from {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. The sum of the digits is 9, so
a + b = 9
Reversing the digits gives the number ba, or
10b + a
which is larger than ab by 45, so
10b + a = (10a + b) + 45
-9a + 9b = 45
a - b = -5
Solve for a and b :
(a + b) + (a - b) = 9 + (-5)
2a = 4
a = 2
Then
a + b = 9
2 + b = 9
b = 7
So the original number if (C) 27.

Who knows thisssss ???
Answer:
(3, 2)
Step-by-step explanation:
y = 5x - 13
3x + 5y = 19
~Substitute since we know what "y" equals
3x + 5(5x - 13) = 19
~Simplify
3x + 25x - 65 = 19
28x - 65 = 19
~Solve for x
28x = 84
28x/28 = 84/28
x = 3
~Solve for y using what we got for x
y = 5(3) - 13
y = 15 - 13
y = 2
Best of Luck!
Answer:

Step-by-step explanation:
3x+5(5x-13)=19

Let |r| = 17 at an angle of 40° and |s| = 14 at an angle of 160°. Which expression represents |r + s|?
ty :3
Answer:
B
Step-by-step explanation:
I got it right on edge2020, 160-40= 120
120/2 = 60 because the angle was gonna be half way between the two angles
The expression that represent | r+s| is Option B
What is a Vector ?A vector is an object that has both magnitude and direction.
It is given that
|r| = 17 at an angle of 40 degree
|s| = 14 at an angle of 160 degree
| r + s| = ?
The magnitude will be determined by the cosine law
and the angle will be 60 degree , obtained from the figure attached with the answer.
[tex]\rm |r + s| = \sqrt{ 17^2 + 14 ^2 -2 * 14 *17 cos 60[/tex]
Therefore , the expression that represent | r+s| is Option B.

A game field is 360 feet long. The practice field is 2/5 shorter than the practice field. How long is the game field?feet
Explain your reasoning.
Answer:
The practice field is 144 feet long.
Step-by-step explanation:
360 x 2/5 = 144
(You would multiply these numbers NOT divide!)
To check my math:
2/5 = 0.4
144/360 = 0.4
By doing the above check, I know the two equations are the same. By seeing this I can know that the answer is correct.
