What is the system of inequalities associated with the following graph?
The system of inequalities associated with the following graph are,
x + y ≥ 2.
4x + y ≥ - 1.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
The coordinates of the first equation is, (0, 2), (2, 0).
Slope(m) = (0 - 2)/(2 - 0).
Slope(m) = - 2/2.
Slope(m) = - 1.
2 = - 1(0) + b.
b = 2.
y₁ = - x + 2.
The coordinates of the second equation is, (- 1, 3), (0, - 1).
Slope(m) = (- 1 - 3)/(0 + 1).
Slope(m) = - 4.
3 = 4 + b.
b = - 1.
y₂ = - 4x - 1.
So, The system of inequalities associated with the graph are,
x + y ≥ 2.
4x + y ≥ - 1.

A circular running tack is 1/4mile long. Elena runs on this track, completing each lap in 1/20of an hour. What is Elena's running speed?
Please add step by step explanation.
Answer:
Elena's running speed is 5 miles/hour
Explanation:
The speed is defined as the covered distance per unit time
In the problem, we have:
The distance covered is the length (circumference) of the circular track which is given as of a mile.
We are also given that she completes each lap (she completes of a mile) in of an hour
To get her speed, we will divide the distance covered by the time taken to cover this distance
This is done as follows:
speed = miles/hour
This means that:
Elena can run 5 miles each hour
Answer:
5 miles per hour

If the approximate height of this right prism with triangular bases is 3.5 centimeters, what is its approximate surface area?
Answer:
74 (square) cm
Step-by-step explanation:
First, to find the surface area of both faces, make each face into two right triangles.
Use the formula A = ab/2 to find the surface area of one of the new right triangles. in this case, A = 2x3.5/2 is equal to 3.5.
Double this to find the full surface area for each face, 7 (square) cm.
Next, find the surface area of the base by multiplying the length by the width. in this case, 4x5 = 20, your base surface area.
Next, find the surface areas of the sides the same way as the base. This example has the same measurements as well. 5x4 = 20.
Last, add all of the solutions together to get the surface are of the whole object. 7 + 7 + 20 + 20 + 20 = 74 (square) cm
Answer:
74 squared

A lighthouse is 160 feet tall. A scale model of the lighthouse has a scale of 1 in: 8 ft. How tall is the model of the lighthouse in inches? Don't put units in your answer!
Answer:
20 inches
Step-by-step explanation:
[tex]heght \: of \:the \: model \: of lighthouse \\ \\ = \frac{1}{8} \times 160 \\ \\ = 20 \: inches[/tex]
Answer:
20
Step-by-step explanation:
You can easily get the answer by using the scale (1 inch: 8 ft) in order to know the value of 160 feet to inches.
Let's solve.
160 feet x [tex]\frac{1 inch}{8 feet}[/tex] = [tex]\frac{160 feet}{8 feet}[/tex]= 20 inches
Basing it on the scale, the value of 160 feet is 20 inches. This means that the model of the lighthouse is 20 inches tall.
In the final answer, the unit was removed because the problem asked not to put units in the answer.

Which is the best estimate for the percent that is represented by the shaded portion of the diagram?
30%
36%
38%
40%
In this diagram, there are a total of 8 squares, and 3 of them are shaded. This means that 3/8 of them are shaded, and to find what percent this is, divide 3 by 8 and multiply what you get by 100.
3 divided by 8 = 0.375
0.375 x 100 = 37.5%.
37.5% is closest to 38%, so that is your answer:)
The 38% that is represented by the shaded portion of the diagram option third 38% is correct.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Total number of boxes = 8
Number of shaded boxes = 3
The percent of shaded boxes = (3/8)×100
= 0.375×100
= 37.5%
or
38%
Thus, the 38% that is represented by the shaded portion of the diagram option third 38% is correct.

Joe and Tim observed two points, P and Q, on a number line.
Joe said that the absolute values of the numbers represented by the two points are different.
Tim said that the absolute values of the numbers represented by the two points are the same.
Which of the following explains who is correct?
Joe, because the points have different signs
Tim, because each point is fraction 3 over 8 unit away from 0
Tim, because the distance between the points is fraction 3 over 8 unit
Joe, because the points are at different locations
Answer:
The answer is Tim, because each point is fraction 3 over 8 unit away from 0.
Step-by-step explanation:
The absolute value is how far away a number is from 0 on a number line so since -3/8 is still 3/8 away from 0 the absolute value would be 3/8.
