At the Wild West amusement park, Florence's favorite ride is the Blazing Bullet roller coaster. The roller coaster normally has a lot of seats to choose from, but Florence noticed that 12 of the seats are now reserved for season pass holders. There are 42 seats remaining for people without season passes. Let s represent the total number of seats on the Blazing Bullet roller coaster. Which equation models the problem?
Answer:
s=42+12
if there were 42 seats remaining and 12 seats reserved, adding both of them together would give you the total number of seats
Answer: s-12=42
Step-by-step explanation:
We don’t see any multiple choice problems but I think the answer would be this.
s-12=42

Write an equation in the standard form to represent the total rent (y) that Sam has to pay for renting the boat for x days. (4 points)
Part B: Write the equation obtained in Part A using function notation.(2 points)
Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals.
I need the most help for part c.
Answer: PART A:
Recall that the equation of a line in standard form is of the form:
ax + by = c
where a, b, and c are constants.
The equation of a line passing through two points:
and
is given by:
Given that Amir rented a scooter at $43 for 3 hours. If he rents the same scooter for 8 hours, he has to pay a total rent of $113.
This,
and
Thus, the equation of the line is given by:
Therefore, the equation of the line in standard form is
PART B:
To write the equation with a function notation, we first express y in terms of x and then change y notation to f(x) notation.
Recall from part 1:
Therefore, the equation obtained in Part A written using function notation is given by:
PART C:
To graph the equation obtained above, we draw the x- and y- axis with the x-axis labelled 'number of hours' and the y-axis labelled 'total rent'.
Next, we choose appropriate scales for x- and y- axis. Depending on the size of your graph book, you can choose an interval of 1 unit for the x-axis and an interval of 10 units for the y-axis.
From part A, we know that the line of the equation passes though points (3, 43) and (8, 113), mark these points and draw a straight line passing theough these points.

A spinner divided into eight equal colored sections, with one orange, two purple, two yellow, and three blue.
Which statement about probability is true?
The probability of landing on orange is greater than the probability of landing on purple.
The probability of landing on yellow is less than the probability of landing on blue.
The probability of landing on orange is equal to the probability of landing on yellow.
The probability of landing on purple is equal to the probability of landing on blue.
The probability of landing on yellow is less than the probability of landing on blue.
Explanation:
The probability of landing on yellow is 2/8, while the probability of landing on blue is 3/8. 2/8 is less than 3/8
None of the other answers can be right, because:
the probability of landing on purple (2/8) is greater than the probability of landing on orange (1/8),
the probability of landing on orange (1/8) is less than the probability of landing on yellow (2/8),
and the probability of landing on purple (2/8) is less than the probability of landing on blue (3/8)

Answer:
y = 3/4x -1/4
Step-by-step explanation:
First, find the slope using the points (3, 2) and (-1, -1):
Slope = m = y2 -y1 / x2 -x1 = -1 -2 / -1 -3 = -3/-4 = 3/4
Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.
-1 = ¾(-1) + b
-1 = -¾ + b
Add ¾ to both sides
-1 + ¾ = b
(-4 + 3)/4 = b
-¼ = b
Substitute m = ¾ and b = -¼ in y = mx + b.
The equation would be:
✅ Y = 3/4x - 1/4

Brown Material (gallons) 12.75 18.6 24 E
Green Material (gallons) 4.25 B D 11.5
Total (gallons) A C 32 46
If Jeremy needs 48 gallons of compost to plant his garden in the spring, how much brown material will he need? How much green material will he need?
Choices:
Jeremy will need 36 gallons of brown material and 12 gallons of green material.
Jeremy will need 30 gallons of brown material and 18 gallons of green material.
Jeremy will need 12 gallons of brown material and 36 gallons of green material.
Jeremy will need 15 gallons of brown material and 33 gallons of green material.
Please explain your answer!!
Answer: Jeremy will need 36 gallons of brown material and 12 gallons of green material.
explanation: I did the test and got the question right. hope this helps!
The correct choice is: Jeremy will need 30 gallons of brown material and 18 gallons of green material.
Brown Material: 12.75, 18.6, 24, E (E is missing, represents the unknown value)
Green Material: 4.25, B (B is missing, represents the unknown value), D (D is missing, represents the unknown value), 11.5
Total: A (A is missing, represents the unknown value), C (C is missing, represents the unknown value), 32, 46
We know that Jeremy needs a total of 48 gallons of compost. So, we can set up an equation:
A + C = 48
From the brown material data, the total brown material is 12.75 + 18.6 + 24 + E:
12.75 + 18.6 + 24 + E = A
From the green material data, the total green material is 4.25 + B + D + 11.5:
4.25 + B + D + 11.5 = C
Now, let's look at the given total values:
A + C = 32 + 46 = 78
We can now set up a system of equations:
12.75 + 18.6 + 24 + E = A ........(1)
4.25 + B + D + 11.5 = C ........(2)
A + C = 78 ........(3)
Now, to find the values of A and C, let's use equation (3):
A + C = 78
From the choices provided, let's try option (A) Jeremy will need 36 gallons of brown material and 12 gallons of green material.
If Jeremy needs 36 gallons of brown material, then A would be 36. Let's see if this fits:
A + C = 78
36 + C = 78
C = 78 - 36
C = 42
Now, let's check if this aligns with the green material:
4.25 + B + D + 11.5 = C
4.25 + B + D + 11.5 = 42
Now, B and D must be positive values, and they need to sum up to 42 - (4.25 + 11.5) = 26.25.
There are various combinations for B and D that satisfy this, such as B = 20 and D = 6.25, or B = 15 and D = 11.25.
But since none of the given values in the green material (4.25, 11.5) match these combinations, option (A) is not the correct answer.
Now let's try option (B) Jeremy will need 30 gallons of brown material and 18 gallons of green material.
Jeremy needs 30 gallons of brown material, then A would be 30. Let's see if this fits:
A + C = 78
30 + C = 78
C = 78 - 30
C = 48
Now, let's check if this aligns with the green material:
4.25 + B + D + 11.5 = C
4.25 + B + D + 11.5 = 48
Now, B and D must be positive values, and they need to sum up to 48 - (4.25 + 11.5) = 32.25.
One combination for B and D that satisfies this is B = 20 and D = 12.25.
Since the values 20 and 12.25 are among the given green material values, option (B) is the correct answer.
So, Jeremy will need 30 gallons of brown material and 18 gallons of green material.
Therefore, the correct choice is:
Jeremy will need 30 gallons of brown material and 18 gallons of green material.

Lyndie is making reduced copies of a photo 25 centimeters in height. She sets the copy machine to an 80% size reduction.
PART A
Write a percent equation that represents the relationship of the height of the first copy to the height of the original photo.
PART B
Lyndie wants to make another copy that will have a height of 17 cm. The copy machine settings increase or decrease in increments of 5%. Which photo should she make her copy from, the original or her first copy? Explain.
Answer:
80% x 25cm = 20cm
First Copy
Step-by-step explanation:
80% x 25cm = 20cm
1.25 is 5% of 25 25-17=8
8/1.25= 6.4 which doesn't go in evenly.

what is the equation of the line slope intercenpt form that passes through the point (8,9) and is parallel to the graph of y=3/4x-2? please explain.
Answer:
Slope-intercept form is y= 4x - 30
Step-by-step explanation:
Step 1: Substitute the slope from original line into the equation of the line
Here slope , m is 4
y= mx +b
where m is the slope
b is the y intercept
So Substituting slope we get,
y= 4x +b--------------------------------------------(1)
Step 2 :Substitute the given point (8,2) into the x and y values of equation (1)
y = 4x +b
2 =4(8) + b
Step 3: Solve for y intercept values
2 = 32+ b
2-32 =b
-30 =b
Now the y intercept value b= -30
Step 3: Substitute this value for 'b' in the slope intercept form equation
Substituting the value in eq (1) we get,
y= 4x +(-30)
y= 4x - 30

Answer:
The y-intercept is (12,0).
The x-intercept is (0,2).
Step-by-step explanation:
X & Y intercepts.• The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.
• These can be easily found by rearranging the equation to standard slope format and plugging 0 into either variable.
Rearrange the equation to y = mx+ b.• -24x - 4y = -48.
• -4y = -48 + 24x.
• Divide the entire equation by -4 to isolate y.
• Y = 12 - 6x.
• Plug 0 into x
○ Y = 12 - 6(0).
○ Y = 12.
• Plug 0 into y
○ 0 = 12 - 6x
○ 6x = 12
○ X = 2
The x intercept is (0,2)
The y intercept is (12,0)

Step-by-step explanation: For the $18 sweatshirt, 20% off would be $14.4. If she uses the $5 rebate, shes getting $5 off or back. She can't use the 3rd discount because it's not over $20.
For the $30 sweatshirt, 20% off of that makes it $24. $5 back from the rebate makes it $25, and half off (50%) makes it $15. Which is the cheapest.
