Answer:
x=2
Step-by-step explanation:
Since both equations are equal to y, we can solve this system by setting them equal to each other:
3x-1=-2x+9
-1=-5x+9
-10=-5x
2=x
x=2
Therefore x=2

i. 10g3 27 ^3
Answer:
9
Step-by-step explanation:
Log₃27³
Recall that 27 = 3³
Hence
Log₃27³ = Log₃3³⁽³⁾ = Log₃3⁹
From the laws of logarithms, we know that
Logₐa = 1 and Log aˣ = xLog a
As such, applying both laws
Log₃3⁹ = 9Log₃3
since Log₃3 = 1
9Log₃3 = 9 * 1
= 9

The interquartile range (IQR) is defined as the difference between the first and third quartiles (Q3−Q1). What feature of the box-and-whisker plot does the IQR describe?
Answer:
The interquartile range is also known as midspread and it is the between the first and third quartile (25th and 75th percentile respectively) serving as a robust measure of sample dispersion.
Interquartile range (IQR) = Q3 - Q1
As a measure of variability, it is based on splitting data sets into quartile (four equal portions). The values differentiating these portions are known as the first, second, and third quartile which are represented as Q1, Q2, and Q3, respectively.

9c + 3 + 13c – 4c + 4 – 24c=?
Answer:
-6c + 7
Step-by-step explanation:
(This question probably requires bodmas)
9c + 3 = 9c + 3
9c + 3 + 13c = 22c + 3
22c + 3 - 4c = 18c + 3
18c + 3 + 4 = 18c + 7
18c + 7 - 24c = -6c + 7

I got (9,4) the first time and it said it was wrong
Answer:
(3,9)
Step-by-step explanation:
9=9x-18
(Add 18 on both sides)
27=9x
(Divide both sides by 9)
3=x
The ordered pair in function f(x) corresponds to the equation will be (3, 9).
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The function is given below.
f(x) = 9x – 18
The value of the function is 9. Then the value of the variable 'x' is given as,
9 = 9x – 18
Simplify the equation, then we have
9 = 9x – 18
9x = 27
x = 3
The ordered pair in function f(x) corresponds to the equation will be (3, 9).

In the Kite Club, there are a total of 23 kids. There are 7 more girls than boys. Write two equations below to represent the situation. Then, graph to find the number of boys and girls in the club.
Answer:
15 girls
Step-by-step explanation:
The two equations represent the situation will be x + y = 23 and x = y + 7. Then the number of girls is 15 and the number of the boys is 8.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
In the Kite Club, there are a total of 23 kids.
Let x be the number of girls and y be the number of boys.
Then the sum of the girls and boys is 23. Then the equation will be
x + y = 23 …1
There are 7 more girls than boys. Then the equation will be
x = y + 7 …2
From equation 1 and 2, we have
y + 7 + y = 23
2y = 23 - 7
2y = 16
y = 8
Then substitute the value of y in equation 2, then the equation will be
x = 8 + 7
x = 15
Then the number of girls is 15 and the number of the boys is 8.
The graph of the equation is attached below.

The odds in favor of an event are 2:9 or 2/9. What are the odds against the event?
Answer:
Odds against the events are 7/9.
Step-by-step explanation:
It is given that:
Odds in favor of event = 2 : 9 or 2/9
Let,
These odds are out of 1.
The odds against the event would be
Odds against = 1 - 2/9
Odds against = [tex]\frac{9-2}{9}[/tex]
Odds against = [tex]\frac{7}{9}[/tex]
