a. The system of inequalities for this situation can be represented as:
x (number of snacks) ≥ 0
y (number of bottles of water) ≥ 0
2x + 2.25y ≤ 70 (total amount of money remaining)
y ≤ 4 (maximum number of bottles of water that can be carried on a tray)
7x + 7y ≤ 70 (total cost of tickets and snacks/drinks cannot exceed the amount given)
b. To graph the system, we can start by plotting the inequality 2x + 2.25y ≤ 70. This represents all the points that satisfy the inequality and forms a boundary line for the feasible region. The line will be a boundary line because it is less than or equal to 70.
We can plot the inequality y ≤ 4 as a horizontal line at y = 4. This represents the maximum number of bottles of water that can be carried.
Finally, we can plot the inequality 7x + 7y ≤ 70 as a boundary line. This represents the total cost of tickets and snacks/drinks that cannot exceed the amount given.
The feasible region will be the area between these lines, above the x-axis and y-axis, and below the line y=4.
The vertices of this feasible region will be the intersection points of the three lines, which are (10,0), (0,10) and (8,4)
c. The combinations of snacks and drinks that are possible are the ones that fall within the feasible region. Any point within the feasible region represents a valid solution in this context, because it satisfies all the constraints and is within the budget.
d. Every point within the feasible region represents a valid solution in this context, because it satisfies all the constraints and is within the budget.
e. One possible combination is (8,4) which is 8 snacks and 4 bottles of water, this combination is possible because it's within the feasible region and satisfies all the constraints. One combination that is not possible is (12,3), it's not possible because it's not within the feasible region and doesn't satisfy the constraint y ≤ 4.
f. To prove that the combination (8,4) is possible, we substitute these values into the system of inequalities:
2(8) + 2.25(4) = 35 ≤ 70 (total amount of money remaining)
4 ≤ 4 (maximum number of bottles of water that can be carried)
7(8) + 7(4) = 56 ≤ 70 (total cost of tickets and snacks/drinks cannot exceed the amount given)
To prove that the combination (12,3) is not possible, we substitute these values into the system of inequalities:
2(12) + 2.25(3) = 30.5 > 70 (total amount of money remaining)
3 > 4 (maximum number of bottles of water that can be carried)
7(12) + 7(3) = 63 > 70 (total cost of tickets and snacks/drinks cannot exceed the amount given)
As all the inequalities are not satisfied, the combination (12,3) is not possible.
What is system of inequalities?A system of inequalities is a set of two or more inequalities that must be satisfied simultaneously. It is a way to represent a set of constraints using mathematical equations. These constraints can be related to a problem in a specific area, such as finance, engineering, or operations research. The solution set of a system of inequalities is the common set of solutions that satisfy all the inequalities in the system. The solutions can be represented graphically as a region in a coordinate plane called the feasible region, which is the set of all possible solutions.

Square ABCD has a diagonal AC with vertices A(-2, 1) and C(2, 4). Find the coordinates of the remaining vertices. Express your answers as decimals, if necessary.
The coordinates are and D.
Answer: To find the coordinates of the remaining vertices of square ABCD, we can use the information given about diagonal AC and the properties of a square. Since a square has equal side lengths and right angles, we know that the distance between opposite vertices on a diagonal must be equal to the side length of the square.
Given the coordinates of vertex A and C, we can use the distance formula to find the length of AC:
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
AC = sqrt((2 - (-2))^2 + (4 - 1)^2)
AC = sqrt(4 + 9) = sqrt(13)
Now that we know the side length of the square, we can use this information to find the coordinates of the remaining vertices. We know that vertex B has the same y-coordinate as vertex A, but the x-coordinate is 2 units to the left of vertex C. Therefore, the coordinates of vertex B are (-2 + 2sqrt(13), 1).
Similarly, we know that vertex D has the same x-coordinate as vertex A, but the y-coordinate is 4 units down from vertex C. Therefore, the coordinates of vertex D are (-2, 1 + 4sqrt(13))
So, the coordinates of the remaining vertices are (2sqrt(13),1) and (-2, 4sqrt(13)) respectively.

Triangles ACD and BCD are isosceles. Angle BAC has a measure of 20 degrees and angles BDC has a measure of 25 degrees. Find the measure of angle ABD
The measure of angle ABD of the described Isosceles triangles is; 115°
What is the measure of the angle in the triangle?The parameters are;
Triangle ΔACD is Isosceles triangle
Triangle ΔBCD is Isosceles triangle
m∠BAC = 20°
m∠BDC = 25°
Whereby ΔBCD and ΔACD have their vertex in the same direction, we can have;
AD ≅ AC Given sides legs of triangle ACD
BD ≅ BC Given sides legs of triangle BCD
BA ≅ BA Reflexive property
Therefore, we can say that;
ΔDAB ≅ ΔCAB by SSS congruency rule
By the CPCTC (Congruent Parts of Congruent Triangles are Congruent), we can say that;
m∠BAC ≅ m∠BAD
Thus;
m∠BAC ≅ m∠BAD = 20°
Therefore;
m∠BAC + m∠BAD = 20° + 20°
m∠BAC + m∠BAD = 40°
Thus, m∠DAC = 40° by the Angle addition postulate
m∠ADC = m∠ACD = (180 - m∠DAC)/2
= (180 - 40)/2 = 70° This is because they are base angles of an isosceles triangle
∴ m∠ADC = m∠ACD = 70°
Similarly;
m∠BDC = 25° = m∠BCD Base angles of isosceles triangle ΔBCD
m∠BCD + m∠DBC + m∠BCD = 180° Sum of the interior angles of a triangle theorem
m∠DBC = 180° - (m∠BCD + m∠BCD)
= 180° - (25° + 25°)
= 130°
m∠DBC = 130°
m∠ABD ≅ m∠ABC by CPCTC
m∠ABD = m∠ABC
Therefore;
m∠DBC + m∠ABD + m∠ABC = 360° Sum of angles at a point
m∠DBC + 2 × m∠ABD = 360°
130° + (2 × m∠ABD) = 360°
2 × m∠ABD = 360° - 130°
2 × m∠ABD = 230°
m∠ABD = 230°/2
m∠ABD = 115°

Which equation represents a tangent function with a domain of all Real numbers such that x is not equal to pi over 4 plus pi over 2 times n comma where n is an integer?
f (x) = tan(2x – π)
g(x) = tan(x – π)
h of x equals tangent of the quantity x minus pi over 2 end quantity
j of x equals tangent of the quantity x over 2 minus pi end quantity
Answer:
A) f(x) = tan(2x - π)
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{8.3cm}\underline{Standard form of a tangent function}\\\\$f(x)=A \tan(B(x+C))+D$\\\\where:\\\\\phantom{ww}$\bullet$ $A=$ vertical stretch\\ \\\phantom{ww}$\bullet$ $\dfrac{\pi}{|B|}=$ period\\\\\phantom{ww}$\bullet$ $C=$ horizontal shift (positive is to the left)\\\\\phantom{ww}$\bullet$ $D=$ vertical shift\\\end{minipage}}[/tex]
The parent tangent function is:
[tex]f(x)=\tan(x)[/tex]
The period of the parent tangent function is π.
A tangent function is discontinuous when cos(x) = 0, so it has vertical asymptotes whenever cos(x) = 0.
Therefore, the parent tangent function has vertical asymptotes at:
[tex]x=\dfrac{\pi}{2}+\pi n[/tex]
and so its domain is:
[tex]\left\{ x \in \mathbb{R} \;| \;x \neq \dfrac{\pi}{2}+\pi n\right\}[/tex]
If the domain of the given tangent function is:
[tex]\left\{ x \in \mathbb{R} \;| \;x \neq \dfrac{\pi}{4}+\dfrac{\pi}{2}n\right\}[/tex]
then its vertical asymptotes are when:
[tex]x =\dfrac{\pi}{4}+\dfrac{\pi}{2}n[/tex]
Therefore, its period is π/2.
[tex]\implies \dfrac{\pi}{|B|}=\dfrac{\pi}{2}[/tex]
[tex]\implies B=2[/tex]
And it has been horizontally shifted by π/2:
[tex]\implies f(x)=\tan\left(2\left(x-\dfrac{\pi}{2}\right)\right)[/tex]
[tex]\implies f(x)=\tan\left(2x-\pi\right)[/tex]
Function g(x)
[tex]g(x)=\tan(x- \pi)[/tex]

2/5k + 1/6 = 3/10k + 1/3
Answer: k = 5/3
Step-by-step explanation:
To solve, we will isolate the variable, k, by using inverse operations.
Given:
2/5k + 1/6 = 3/10k + 1/3
Subtract 1/6 from both sides of the equation:
2/5k = 3/10k + 1/6
Subtract 3/10k from both sides of the equation:
1/10k = 1/6
Divide both sides of the equation by (1/10), which is the same as multiplying both sides by 10:
k = 5/3
Answer:
k=5/3
Step-by-step explanation:
2/5k+1/6=3/10k+1/3
Move the 3/10k to the left side with subtraction
1/10k+1/6=1/3
Move the 1/6 to the right with subtraction
1/10k=1/6
Divide the 1/10 from each side
Getting K=5/3

Which of these is a complex number?
A. 9+3√5
B.8/3+ √-7/3
c. 5√-7
D. 2 - 11
용
The correct answer is B.We can find by complex number by using complex form.
What is a complex number?Complex numbers are the numbers that are expressed in the form of a+ib where a and b are real numbers and 'i' is an imaginary number called “iota”. The value of i = (√-1). For example 2+3i is a complex number where 2 is a real number (Re) and 3i is an imaginary number (Im).
Why complex number is not a real number?Every real number is a complex number when the imaginary part is zero. But remember that every complex number is not a real number. For example we can write 5 as 5+0×(i). Hence Every Real Number is a Complex Number.
Now
A complex number is of the form a+ b(i)
=8/3 +[tex]\sqrt{-7/3}[/tex]
=8/3 +[tex]\sqrt{7/3}[/tex] [tex]\sqrt{-1}[/tex]
=8/3+[tex]\sqrt{7/3}[/tex] (i)
The second option is a complex number because it can be rewritten in the form
a + b(i).

What is transformation function and how to write new equation from transformation function? A transformation function is a mathematical function used to transform a set of data points from one coordinate system to another. The transformation function takes the form of an equation that expresses a relation between two variables. It is commonly used in sciences such as physics and engineering to convert data from one coordinate system to another.For example, if one measure the position of an object in Cartesian coordinates (x,y), the transformation function allows one to express the position of the same object in polar coordinates (r,θ). This can be written as: r = sqrt(x2 + y2); θ = arctan(y/x)To write a new equation from a transformation function, one must first determine the desired coordinate system. Then, one can use the transformation function to find the relation between the two variables in the given coordinate system. For example, if one wants to express the position of an object in Cartesian coordinates from polar coordinates, the equation would take the form: x = r*cos(θ) ; y = r*sin(θ)This equation expresses the relation between the two variables in Cartesian coordinates. Then, one can use this equation to determine the position of any object in Cartesian coordinates given its position in polar coordinates.To learn more about transformation function refer to:

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 )
