The initial number of party favor bags Razee had to fill were 48 bags.
Here, we will use arithmetic progression to solve this problem.
We are given that:
At 4 minutes, 36 bags were remaining.
At 5 minutes, 32 bags were remaining.
At 6 minutes, 28 bags were remaining.
At 7 minutes, 24 bags were remaining.
This can also be written as:
a₄ = a + 3d = 36
a₅ = a + 4d = 32
a₆ = a + 5d = 28
a₇ = a + 6d =24
where a is the initial number of party favor bags.
a₅ - a₄ = a + 4d - a - 3d
a + 4d - a - 3d = 32 - 36
d = -4
a + 3d = 36
a + 3(-4) = 36
a - 12 = 36
a = 36 + 12
a = 48
Therefore, the initial number of party favor bags Razee had to fill were 48 bags.

2.A
Answer:
1. x = 4, y = 1
Graph: (See the attachment)
Step-by-step explanation:
x + 2y = 6
x - y = 3
x + 2y = 6
x = -2y + 6
x - y = 3
-2y + 6 - y = 3
-3y + 6 = 3
-3y = -3
y = 1
x = -2y + 6
x = -2 ( 1 ) + 6
x = 4
The graph shows the amount of money in Amy's bank account and her spending activity. Does the graph show a proportional relationship?
A. Yes, it is proportional because it has a constant rate of change.
B. No, it is not proportional because it has a constant rate of change.
C. Yes, it is proportional because it has a y-intercept.
D. No, it is not proportional because it has a y-intercept that is not zero.
Answer:
Option A:
Yes, it is proportional because it has a constant rate of change.
Step-by-step explanation:
One trick you can use to easily tell a proportional graph is that it follows a straight line. It does not matter whether the line slopes downwards or upwards. The fact that it is straight and not cured at any point, should hint you that the graph is proportional.
Proportional graphs have a constant rate of change. The value of the slope calculated when using any two (x, y) coordinates are the same for any point along the line.

Complete question :
At Alan's auto shop, it takes him 9 minutes to do an oil change and 12 minutes to do a tire change. Let x be the number of oil changes he does. Let y be the number of tire changes he does. Using the values and variables given, write an inequality describing how many oil changes and tire changes Alan can do in less than an hour ( minutes).
Answer:
9x + 12y < 120
Step-by-step explanation:
Given that:
Time taken for oil change = 9 minutes
Time taken for tire change = 12 minutes
x = number of oil changes ; y = number of tire changes
Total hours = 1 hour = 60 minutes
Number of oil and Tyre changes possible in less than an hour
(Number of oil changes * time taken) + (number of tire changes * time taken) less than 60 minutes

At what rate, in gallons per hour, is the swimming pool being filled?
A. 15 gallons per hour
B. 4000 gallons per hour
C. 66.6 gallons per hour
D. 2000 gallons per hour
Answer: 4,000
Step-by-step explanation:
The solution is Option A.
The rate at which the swimming pool is being filled is 66.6 gallons per hour
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the number of gallons be = y
Let the time taken be = x
The total volume of the pool = 15000 gallons
The pool is filled at constant rate
Now ,
The coordinate data is given as
The value of A = A ( 15 , 1000 )
The value of B = B ( 30 , 2000 )
The value of C = C ( 45 , 3000 )
Now , the rate at which the swimming pool is filled is given by the slope of the points in the line
So , the slope of the 2 points is given by the formula
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 2000 - 1000 ) / ( 30 - 15 )
On simplifying the equation , we get
Slope m = 1000 / 15
Slope m = 66.66 gallons per hour
Therefore , the value of A is 66.6 gallons per hour
Hence ,
The rate at which the swimming pool is being filled is given by the slope of the line where slope m = 66.6 gallons per hour

in the graph shown below, if lines 1^1 are parallel, then the slope of the line 1^2 is?
Answer:
Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.Step-by-step explanation:
good morningIf the lines l1 and l2 are parallel, then the slope of line l2 is the same as the slope of line l1.
The slope-intercept definition of a linear function is given as follows:
y = mx + b.
For which the parameters are given as follows:
m is the slope, representing the rate of change of the function.
b is the intercept, representing the value of y when x = 0.
When two lines are parallel, they have the same slope.
Hence, If the lines l1 and l2 are parallel, then the slope of line l2 is the same as the slope of line l1.

There are two similar triangles in the diagram. Find the unknown measurement.
Answer: x=180
Step-by-step explanation:
360/120=x/60
3=x/60
x=180
By the similarity of triangles the length of the side RS is 180 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know in similar triangles the ratio of their corresponding sides are equal.
Given, Are two triangles OPQ and ORS.
Therefore,
OP/PR = PQ/RS.
120/360 = 60/x.
120x = 21600.

Answer:
vegetarians= 28

let the number of vegetarians be x
and chickens be y

x+2.7y=119.6----------1
x+y=72--------------2
from 2, x= 72-y
put x= 72-y in 1
72-y+2.7y=119.6
-y+2.7y=119.6-72
1.7y=47.6
