What is Inequality?
To compare two or more mathematical expression in a relation is called an inequality.
Given that;
The expression is;
A number x is more than -6 and at most -1.
Now, The number x is more than -6.
It can be written as;
-6 < x
And, The number x is at most -1.
It can be written as;
x ≤ -1
After combine both inequality, we get;
- 6 < x ≤ -1.
Thus, The expression is written as;
-6 < x ≤ -1

The piece-wise function is defined by:
[tex]f(x) = 1, -3 \leq x < -1[/tex]
[tex]f(x) = 2, -1 \leq x < 1[/tex]
[tex]f(x) = 3, 1 \leq x < 3[/tex]
A piece-wise function is a function that has different definitions, based on the input.
In this graph:
When x is between -3(inclusive, closed circle) and -1(exclusive, open circle), the value is 1, thus, the first definition is:[tex]f(x) = 1, -3 \leq x < -1[/tex]
When x is between -1(inclusive) and 1(exclusive), the value is 2, thus, the second definition is:[tex]f(x) = 2, -1 \leq x < 1[/tex]
When x is between 1(inclusive) and 3(exclusive), the value is 3, thus, the third definition is:[tex]f(x) = 3, 1 \leq x < 3[/tex]

△ABC is reflected over the x−axis and then reflected over the y−axis to form ΔA''B''C'' as shown below.
Answer:
D
Step-by-step explanation:
Because it is.
The general rule maps △ABC onto ΔA''B''C'' is (x,y) turns to (x, -y). so option C is correct.
How does reflection across axis work?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If we study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
Thus, if we are reflecting a point (x,y) along x axis, then its abscissa will stay same but ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if we are reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)
△ABC is reflected over the x−axis and then reflected over the y−axis to form ΔA''B''C'' is shown.
The general rule maps △ABC onto ΔA''B''C'' is (x,y) turns to (x, -y). so option C is correct.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
It was 43'F when the temperature was first measured, and it is dropping by 2 degrees per hour.
Option D is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 8 is an equation.
We have,
y = -2x + 43
Where y is the temperature after x hours.
Now,
At x = 0,
y = 43
This means the temperature is 43 when it first started to measure.
At x = 1,
y = 41
This means,
The temperature decreases by 2 degrees per hour
Thus,
It was 43'F when the temperature was first measured, and it is dropping by 2 degrees per hour.
Option D is the correct answer.

(PLEASE SOLVE ASAP!!) Suppose the entry fee to Arches national park is $25 per vehicle. Suppose the entrance fee to Bryce national park can be represented by the equation y=30x, where y represents the total cost in dollars, and x represents the number of vehicles. Which park has the greatest cost per vehicle?
Answer:
Bryce national park has the greatest cost per vehicle.
Step-by-step explanation:
From the question, we are given the following:
For Arches national park
Cost per vehicle or entry fee per vehicle at Arches national park = $25
For Bryce national park
We have:
y = 30x ........................... (1)
y = the total cost in dollars
x = the number of vehicles
To obtain the cost per vehicle at Bryce national park, we have to assume that the number of vehicles is one by setting x equal to one, that is, x = 1.
Substituting x = 1 into equation (1), we have:
y = 30 * 1 = 30
This implies that cost per vehicle at Bryce national park is $30.
Conclusion
Since the $30 cost per vehicle at Bryce national park is greater than the $25 cost per vehicle at Arches national park, it therefore implies that Bryce national park has the greatest cost per vehicle.

Mr.Sampson fills the family pool with water for the summer, after two hours, the water has reached the depth of 2.5 feet.After three hours the water level has riden to 3 3/4
This question is incomplete
Complete Question
Mr Sampson fills the family pool with water for the summer.After two hours,the water has reached a depth of 2.5 feet. After three hours,the water level has risen to 3 3/4 feet.If the relationship between time and water depth is proportional,what is the constant of proportionality?
Answer:
1.33
Step-by-step explanation:
Time is proportional to Depth
Hence:
T ∝ D
T = kD
Where k is the constant of proportionality
After two hours,the water has reached a depth of 2.5 feet. After three hours,the water level has risen to 3 3/4 feet.
Total number of hours now is 3 + 2 = 5 hours
5 = k × 3 3/4
5 = k × 3.75
k = 5/3.75
k = 1.33

Sam has some pennies, dimes and nickels in his pocket which total 52 cents. He has two more nickels than dimes and three times as many pennies as nickels. How many of each coin does he have?
Answer:
Step-by-step explanation:
Let the amount of pennies be x
amount of dimes be y
amount of nickels be z
If it all totaled 52, then x+y+z = 52
If he has two more nickels than dime, then;
z = y + 2
y = z-2
If he has three times as many pennies as nickels;
3x = z
x = z/3
Subtitute the funcion in original function;
z/3 + (z-2) + z = 52
z + 3z - 6 + 3z = 156
7z - 6 = 156
7z = 162

A tree casts a shadow that is 125 feet in length. The angle of elevation with the sun is 32°. What is the height of the tree?
Answer:
Height of the tree is 78.11 feet.
Step-by-step explanation:
By applying the tangent rule in the right triangle formed,
Since, tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(32)° = [tex]\frac{h}{125}[/tex]
h = 125(tan32°)
h = 125(0.62487)
h = 78.109
≈ 78.11 ft
Height of the tree will be 78.11 feet.
