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?
Answers
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

The overlap effects the calculation of the surface area because the bottom of the yellow block and a part of the purple block overlaps making it so that you would count it two times instead of the area that is visible.

art A: Sam rented a boat at $225 for 2 days. If he rents the same boat for 5 days, he has to pay a total rent of $480.
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.

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,

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.

Mrs. Lowry is ordering car decals for each family to put on their cars for the upcoming baseball season. She ordered 25 decals. She got a deal on them and they will be $2 cheaper for each decal. The total came to $250. Write an equation to find the amount, d, for the normal cost of each car decal without the deal.
What is the normal cost of each decal without the deal?
Answers
Answer:
$12----------------------
Let the cost of each car decal is d.
After applying a discount of $2 the total for 25 decals came to $250.
Set up an equation:
25(d - 2) = 250Solve it for d:
25(d - 2) = 250d - 2 = 250/25d - 2 = 10d = 10 + 2d = 12The normal cost of each decal is $12.

Include in Your Answer:
The linear equation written in y=mx + b format.
1 to 2 sentences explaining how you determine the correct linear equation.
Answers
Answer:
The linear equation showing the total cost of tiling Dani's bathroom floor is: y = 3x + 50
The equation is in the form of "y = mx + b", where y represents the total cost, x represents the number of square feet, m represents the cost per square foot ($3), and b represents the fixed cost ($50). The linear equation is determined by using the information provided in the problem, which is the cost per square foot and the fixed cost.

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

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.
Answers
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
hope this helps!

The table will fit because 2 and StartFraction 5 Over 8 EndFraction < 2 and three-fourths.
The table will fit because 2 and StartFraction 5 Over 8 EndFraction > 2 and three-fourths.
The table will not fit because 2 and StartFraction 5 Over 8 EndFraction < 2 and three-fourths.
The table will not fit because 2 and StartFraction 5 Over 8 EndFraction > 2 and three-fourths.
Answers
Answer:
The table will fit
Step-by-step explanation:
Table: 2 3/8 = 19/8
Door: 2 3/4 = 11/4
(Mixed fraction to Improper fraction)
Door: 2 3/4 = 11/4 = 11/4*2 = 22/8
19/8 (Table) > 22/8 (Door)
