The difference in price per passenger for a group of 16 versus a group of 10 is $26.25
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
From the graph:
The cost for a group of 16 friends is $2500, while for a group of 10 friends is $1300.
Cost per passenger for 16 friend = $2500 / 16 = $156.25
Cost per passenger for 10 friend = $1300 / 10 = $130
The difference in price = $156.25 - $130 = $26.25
The difference in price per passenger for a group of 16 versus a group of 10 is $26.25

Part 1)
we have
------> equation A
------> equation B
Multiply by 
the equation A
------> equation C
Multiply by 
the equation B
-------> equation D
Adds equation C and equation D
therefore
<u>the answer Part 1) is the option A </u>
Part 2)
we have
------> equation A
Simplify Divide by 
both sides
------> equation B
the lines A and B are parallel lines, because the slope m is equal
so
The system has no solution
therefore
<u>the answer Part 2) is the option D</u>
There is no x value as there is no solution to the system.
Part 3)
we have
------> equation A
------> equation B
substitute equation B in equation A
![4x+2[x-3]=6](https://tex.z-dn.net/?f=4x%2B2%5Bx-3%5D%3D6)
therefore
<u>the answer part 3) is the option D</u>
Part 4)
Let
x---------> The number of one-step equations
y---------> The number of two-step equations
we know that
-------> equation A
------> equation B
substitute equation A in equation B
![3[1,120-y]-2y=1,300](https://tex.z-dn.net/?f=3%5B1%2C120-y%5D-2y%3D1%2C300)
therefore
<u>the answer part 4) is the option D</u>
Answer: The mean temperature for the first eight days is 6.5 degrees
Step-by-step explanation: The most important piece of clue has been given which is the mean (average) for the observed data set, which is 7 days.
Note that the formula for the mean of a data set is derived as;
Mean = ∑x / f
Where ∑x is the summation of all observed data set and f is the number of data observed, that is 7. The formula now becomes;
6 = ∑x / 7
By cross multiplication, we now have,
6 * 7 = ∑x
42 = ∑x
This means the addition of all temperature observed on the first 7 days is 42. The temperature on the eighth day is now given as 10 degrees, this means the summation of all observed data for the first eight days would become 42 + 10 which equals 52. Therefore when calculating the mean for the first eight days, ∑x is now 52. The formula for the first eight days therefore is derived as follows;
Mean = ∑x / 8
Mean = 52 / 8
Mean = 6.5
The calculations therefore show that the mean temperature for the first eight days in January is 6.5 degrees
Answer:
The domain is all real numbers except x=3
Step-by-step explanation:
Assuming you mean
f(x) = 1/(x-3)
The domain is all numbers that x can take
This function is define except when the denominator goes to zero
x-3 cannot be zero
x cannot be 3
The domain is all real numbers except x=3
Answer:
x^3 + 6x^2 + 12x + 8
Step-by-step explanation:
(x+2)(x+2)(x+2)
(x^2 + 4x + 4)(x+2)
x^3 + 2x^2 + 4x^2 + 8x + 4x + 8
x^3 + 6x^2 + 12x + 8
