9. Ian and his friends are renting a cabin that
charges an initial fee plus a rate per night. The
relationship between the cost and the number of
nights is shown in the graph.
Answer:
taken from another post
Step-by-step explanation:
Answer:
Cost per night: 75
Equation:
Step-by-step explanation:
An equation to represent the situation can be written in the slope-intercept form, , where,
m = slope of the graph, which is the rate per night.
b = y-intercept, which is the initial fee. It is the point where the line intercepts the y-axis.
Let's find m, using two points on the line, (2, 200) and (4, 350)
✅The cost per night = 75
y-intercept, b, = 50. The line intercepts the y-axis at y = 50, when x = 0.
Substitute m = 75, and b = 50 into .
✅The equation would be:

which of the following pairs of functions are inverses of each other
Answer:
c would be the answer you are looking for and please mark brainliest
Step-by-step explanation:
Options A and D have functions that are inverses of each other.
What is an inverse function?The inverse function is defined as a function obtained by reversing the given function.
To check whether two functions are inverses of each other, we need to check if the composition of the functions in both orders results in the input value.
Here, we need to check if f(g(x))=x and g(f(x))=x for all values of x in their domains.
A. f(x) = 7/(x-9) and g(x) = (x+9)/7
f(g(x)) = f((x+9)/7) = 7/((x+9)/7 - 9) = 7/(x/7) = x, so f and g are inverses of each other.
B. f(x) = x/6 + 8 and g(x) = 6x - 8
f(g(x)) = f(6x-8) = (6x-8)/6 + 8 = x/6 + 8/6 = x/6 + 4/3, which is not equal to x. Therefore, f and g are not inverses of each other.
C. f(x) = 2 + ∛x and g(x) = 2 - x³
f(g(x)) = f(2 - x³) = 2 + ∛(2 - x³) ≠ x, so f and g are not inverses of each other.
D. f(x) = 5x - 11 and g(x) = (x+11)/5
f(g(x)) = f((x+11)/5) = 5((x+11)/5) - 11 = x, and g(f(x)) = g(5x-11) = (5x-11+11)/5 = x/5, so f and g are inverses of each other.
Therefore, only options A and D have functions that are inverses of each other.

Answer:
D. 24 Units
Step-by-step explanation:
tracing the points given we get a rectangle
the perimeter of a rectangle = 2a+2b

in this case a= 8
b= 4
the perimeter of a rectangle = (2*8)+(2*4)
the perimeter of a rectangle = 16+8

5. Bobby guessed there were 92 jelly beans in a jar. There were actually 107 2 points
jellybeans. Find the percent of error. Round to the nearest hundredth of a
percent if necessary.
HELP IM IN A QUIZZZ
Answer: 14%
Step-by-step explanation:
From the question, we are informed that Bobby guessed there were 92 jelly beans in a jar when there were actually 107. The percentage error will be:
= Difference in error / Actual value × 100
= (107 - 92) / 107 × 100
= 15/107 × 100
= 0.14 × 100
= 14%

You buy 4 breakfast sandwiches at $2.59 each, 4
hashbrowns at $1.10 each, and 4 bottles of orange
juice at $1.25 each. The sales tax is 6%. Find the
total cost of the 4 meals, including sales tax.
Answer:
all 4 meals equal $20.95
Step-by-step explanation:
4 sandwiches = $2.59 each
4 hashbrowns = $1.10 each
4 orange juice = $1.25 each
sales tax = 6%
now you have two options you could either add all of the one meal prices together or you could do how much it would cost for the each individually
adding one meal
2.59 + 1.10 + 1.25 = 4.94
4.94 x 4 = 19.76
adding all the items individually
2.59 x 4 = 10.36
1.10 x 4 = 4.40
1.25 x 4 = 5.00
10.36 + 4.40 + 5.00 = 19.76
now if the sales taxes
19.76 x 0.06 = 1.19
now sales taxes plus all the items
19.76 + 1.19 = 20.95

What is 4/5 divided by 3/4 as I fraction in simplest form
Answer:
1 1/15
Step-by-step explanation:
1. Change the division sign to a multiplication sign. (4/5) x (3/4)
2. Flip 3/4. (4/5) x (4/3)
3. Multiply the numerators together and multiply the denominators together. 16/15
4. Simplify. 1 1/15
4/5 ÷ 3/4 is 1 1/15
4/5 ÷ 3/4
To perform division :
Numerator = 4/5
Numerator = 4/5 Denominator = 3/4
Take the reciprocal of the denominator and use the multiplication operator :
Reciprocal of 3/4 = 4/3
4/5 × 4/3 = (4 × 4) / (5 × 3) = 16/15 = 1 1/15
Hence, 4/5 ÷ 3/4 = 1 1/15
