Blake was a little concerned as he stood in the middle of the overcrowded elevator. The sign clearly stated that the total weight in the elevator could not exceed 2,000 pounds.
Write an inequality to show the weight limit for the elevator.
A) w > 2,000
B) w < 2,000
C) w ≤ 2,000
D) w ≥ 2,000
Answer: C) w ≤ 2,000
Step-by-step explanation:
We know for a fact that it is not A or D, because this means that the elevator WOULD be able to handle weight more than or equal to 2,000 lbs.
This leaves us A and C.
The question states that the weight could not exceed 2,000 pounds, meaning that ≤ will be used. This gives us w ≤ 2,000. The total weight in the elevator has to be less than or equal to 2,000 pounds.

Write the statement "the sum of a number and 17.3 is at least −2.8" as an inequality.
I need this asap
Answer: 17.3
Step-by-step explanation:
The linear inequality for the statement " the sum of a number and 17.3 is at least −2.8" is b + 17.3 ≥ - 2.8 which is option B
We are given that the sum of a number and 17.3 is at least −2.8 and we have to form a linear inequality from the information provided
Let the number be b
so, the sum of two numbers would be
b + 17.3
It is given that the sum should be at least - 2.8
this means the sum is either equal to - 2.8 or sum is more than -2.8
So, the linear inequality equation comes to be
b + 17.3 ≥ - 2.8
Hence, the linear inequality for the statement " the sum of a number and 17.3 is at least −2.8" is b + 17.3 ≥ - 2.8
Answer:

Step-by-step explanation:
I looked on a calculator
The answer to the problem is 0.9 or 9/10.
As it is given 3/8 divided by 5/12 it should be like this:
⇒ 3/8÷5/12
⇒ 3/8×12/5
⇒ 3/2×3/5
⇒ 9/10
⇒ 0.9
As dividing 3/8 by 5/12 will simply be reciprocal 5/12 to 12/5 and after that, it is a simple multiplication step.

Determine if the graph shows a proportional relationship.
Yes, it is proportional because the line intersects with the origin.
Yes, it is proportional because the axes are numbered correctly.
No, it is not proportional because the line does not intersect with the origin.
No, it is not proportional because the points do not make a straight line.
Answer:
option 1
Step-by-step explanation:
If a relationship is proportional it will cross the origin (0,0) and it will be a straight line.
By looking at the graph, we can identify that this is a straight line.
And there is a point over the origin (0,0)
So we can say that this graph is proportional because the line intersects with the origin.
(the axis being numbered correctly does not identify whether a relationship is proportional so we rule out the second answer)

Answer: y = 5184x
Step-by-step explanation:
Yes, there is a relationship because, logically, there should be a set amount of pixels changing when the area changes. This data table shows a linear relationship between the square inches of the screen and the number of pixels. To create a linear equation, we need to know the parent function for linear equations: y=mx + b, where "m = rate of change" and "b = initial value or y-intercept"
To find the rate of change (i.e., the slope). To find the rate of change of a linear function, use the formula (y2-y1)/(x2-x1). This formula works because it's essentially using the "rise/run" method of finding the rate of change.
Using the rate of change formula:
(373248-31104) / (72-6) = 5184
We know the rate of change is 5184, and now we simply have to find the "b" value, which is the y-intercept. We do this by plugging in values we know into the y=mx + b equation.
m = 5184, and we can use any set of points in the table for "x" and "y"
31104 = 5184(6) + b
Now, we isolate "b":
31104 - 5184(6) = b
0 = b
The y-intercept ("b" value) is zero, so we can now plug that into our equation:
y = 5184x + 0
y = 5184x

6y + 14 = -5y - 8. what is the value of y?
Answer:
y=-2
Step-by-step explanation:
Let's solve your equation step-by-step.
6y+14=−5y−8
Step 1: Add 5y to both sides.
6y+14+5y=−5y−8+5y
11y+14=−8
Step 2: Subtract 14 from both sides.
11y+14−14=−8−14
11y=−22
Step 3: Divide both sides by 11.
11/11y=-22/11
y=-2
answer:
y=-2

The value of y for the expression 6y + 14 = -5y - 8 will be y=-2.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Let's solve your equation step-by-step.
6y+14=−5y−8
Step 1: Add 5y to both sides.
6y+14+5y=−5y−8+5y
11y+14=−8
Step 2: Subtract 14 from both sides.
11y+14−14=−8−14
11y=−22
Step 3: Divide both sides by 11.
11/11y=-22/11
y=-2
Hence, the value of y is equal to -2.

The total cost for laundry service, in dollars, depends on the weight of the laundry, in pounds. This relationship is proportional, as it costs $24.65 for 29 pounds of laundry and $36.55 for 43 pounds of laundry.
In words, describe the graph of the proportional relationship.
A line from (0, 0) going through (24.65, 29) where the x-axis is labeled Weight (in pounds) and the y-axis is labeled Cost (in dollars)
A line from (0, 0) going through (29, 24.65) where the x-axis is labeled Cost (in dollars) and the y-axis is labeled Weight (in pounds)
A line from (0, 0) going through (43, 36.55) where the x-axis is labeled Cost (in dollars) and the y-axis is labeled Weight (in pounds)
A line from (0, 0) going through (43, 36.55) where the x-axis is labeled Weight (in pounds) and the y-axis is labeled Cost (in dollars)
The graph of this proportional relationship is described by: A. line from (0, 0) going through (24.65, 29) where the x-axis is labeled Weight (in pounds) and the y-axis is labeled Cost (in dollars).
What is a graph?In Mathematics, a graph simply refers a type of chart that is typically used to graphically represent data points on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate (x-axis) and y-coordinate (y-axis).
Generally speaking, the graph of any proportional relationship is always characterized by a straight line with the data points passing through the origin (0, 0) because as the values on the x-axis increases or decreases, the values on the y-axis increases or decreases simultaneously.
By critically observing graph of this proportional relationship (see attachment), we can logically deduce that it passes through both points (24.65, 29) and (36.55, 43).

A wheat farmer plows 5 acres of land and collects 135 bushels of wheat. The next day, the farmer plows 8 acres of land and collects 216 bushels of wheat.
Is there a proportional relationship between the number of bushels of wheat collected and the number of acres plowed over the two days? Explain.
Yes, it is proportional because the farmer collected 7 bushels for every 1 acre plowed.
Yes, it is proportional because the farmer collected 27 bushels for every 1 acre plowed.
No, it is not proportional because both variables cannot be zero at the same time.
No, it is not proportional because all ratios between the number of bushels collected and the number of acres plowed are not equivalent.
Answer:
Your answer would be the second one:)
Step-by-step explanation:
Yes, it is proportional because the farmer collected 27 bushels for every 1 acre plowed. Option B is correct.
As mentioned in the question, a wheat farmer plows 5 acres of land and collects 135 bushels of wheat. The next day, the farmer plows 8 acres of land and collects 216 bushels of wheat.
What is proportionality?Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
Let the number of land plows be x, and the number of bushels collected be y.
According to the question,
If the relationship between the plows and bushels is proportional then the ratio of bushels to plows or vice versa should be constant,
So,
y/x= k
or,
x₁/x₂ = y₁/y₂
Now,
5/8 = 135/216
5/8 = 5/8
And the value of the constant of proportionality is given as,
k = y/x
k =135/5
k = 27 bushels for every 1 acre plowed.
Thus, Yes, it is proportional because the farmer collected 27 bushels for every 1 acre plowed. Option B is correct.
