The answers are 12x+8y≥1000, 12x+8y≤1000, x+y≤200, and x+y≥200,
The explanation behind the first equation is 12x signifies the regular tickets, being at $12 each. And 8y signifies the student tickets being $8 each. The symbol is "≥", because the manager wants $1000 or more from the ticket sale. While the second equation, just the same with the first but the symbols differ since the sale could be lesser than 1000.
The explanation behind the third equation is 200 is the number of seats at most. In the fourth equation, if many people came, they would lack seats so that’s why the greater sign is used.

Answer:
a. They are same side interior angles. Angle A measures 55°.
They are same side interior angles. Angle A measures 55° which is correct option(A).
What are Interior angles?Interior angles is defined as those that lie inside a shape, or those that are located in the region enclosed by two parallel lines that cross each other at a horizontal angle.
What are Alternate Interior Angles?Alternate Interior Angles is defined as these angles are created when a transversal intersects two parallel lines. The opposing sides of the transversal produce this non-adjacent pair of angles.
What are Vertical angles?Vertical angles is defined as when two lines meet each other at a point. They are always equal to each other, In other words, four angles are created anytime two lines cross or intersect.
What are corresponding angles?Corresponding angles is defined as any pair of angles that are both on the same side of the transversal and of one of the two lines that it intersects.
Given angle measure as 125°
Therefore, they are same side interior angles. Angle A measures 55°.

B 9.22What is the equation in point-slope form for the line parallel to y = -2x + 10 that contains J(6, 8)?
a. y - 8 = -2(x - 6)
b. x - 8 = 2(y - 6)
c. y - 8 = 2(x - 6)
d. y + 8 = -2(x - 6)
Answer: Hello mate!
A linear equation has the form y = ax + b
where x is the variable, a is the slope and b is the x-intercept.
We want to find the pararel line to y = -2x + 10
A paralel line of this, will be another line with the same slope ( -2 in this case) and a different x-intercept; then our line has the shape of:
y = -2x + b
and we know that this line pases through the point (6,8), and with this info we could find the value of b:
8 = -2*6 + b
b = 8 + 12 = 20
then y = -2x + 20 is the pararel line that passes through the point (6.8)
Then the correct answer is the option a:
a) y - 8 = -2(x - 6) = -2x + 12
y = -2x + 12 + 8 = -2x + 20
Is the following relation a function? {(0.3,0.6),(0.4,0.8),(0.3,0.7),(0.5,0.5)}
Answer:
No, the given relation is not a function.
Step-by-step explanation:
Consider the given relation
[tex]\{(0.3,0.6),(0.4,0.8),(0.3,0.7),(0.5,0.5)\}[/tex]
We need to check whether the given relation is function or not.
A relation is a function if there exist a unique value of y for each value of x.
In the given relation, for x=0.3 there exist more than one value of y.
y=0.6 at x=0.3
y=0.7 at x=0.3
For one input there exist more than one output. Therefore, the given relation is not a function.

Ten times the square of a non zero number is equal to eighty times the number
What is the number?
The Number in the statement is 4/5.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Ten times the square of a non zero number is equal to eighty times the number.
let the number be x.
So, 10x² = 8x
10x² - 8x= 0
2(5)(x)(x) - 2 (2)(2)(x) = 0
2x( 5x - 4)= 0
Now, 2x= 0 or 5x-4=0
x= 0 or x= 4/5
Hence, the number is 4/5.

For a craft project, two equilateral triangles are taped together to create a quadrilateral. What is the quadrilateral? rhombus rectangle trapezoid square
Answer:- The quadrilateral must be a rhombus.
Explanation:-
Given :-For a craft project, two equilateral triangles are taped together to create a quadrilateral.
We know that an equilateral triangle is a triangle in which all the sides and angles are equal such that its each interior angle should be 60°.
If we join two equilateral triangle by to create a quadrilateral then the sides of the quadrilateral would be same as it was constructed by equilateral triangle.
Then the interior angle for the sides which are not joint will remain same as 60°.
But the interior angle for the vertex of quadrilateral which has formed by joining two triangles will become 60°+60°=120°.
Thus it is not a square , rectangle (no right angle )or trapezoid(quadrilateral have equal sides).
Therefore, the quadrilateral must be a rhombus.
Given m∠P = 38° and m∠O = 70°, find m∠1.
38
72
108
142
pls
Answer:
The answer is m∠1 = 72°
Step-by-step explanation:
One of the properties of a triangle is that all the angles of the triangle must add up to 180°.
Therefore:
m∠P + m∠O + m∠1 = 180°
Given that:
m∠P = 38° and m∠O = 70°
We can conclude that:
38° + 70° + m∠1 = 180°
m∠1 = 180° - 38° - 70°
m∠1 = 72°
Which equation could be used to solve the given problem: if three times a number is increased by 24, the result is 4 less than seven times the number?
The equation of the given problem would be 3x + 24 = 7x - 4 and the solution is 7.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We have given that "if three times a number is increased by 24, the result is 4 less than seven times the number"
Let the number be x then we have;
three times a number means 3x
seven times the number means 7x
Therefore, the equation will be;
3x + 24 = 7x - 4
Now solving for x unknown number;
3x + 24 = 7x - 4
24 + 4 = 7x -3x
28 = 4x
x = 7
Hence, the equation of the given problem would be 3x + 24 = 7x - 4, and the solution is 7.

The length of the other diagonal, DF is 44 cm.
What is the Pythagorean theorem?Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We can apply this theorem only in a right triangle.
Example:
The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.
Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm
We have,
Since the kite has two pairs of congruent adjacent sides, we know that the diagonals of the kite are perpendicular bisectors of each other.
Therefore, we can use the Pythagorean theorem to find the length of the other diagonal DF.
Let x be the length of the other diagonal, DF.
We know that one diagonal EG has a length of 24 cm, so we can use the Pythagorean theorem to find the length of the perpendicular bisector of EG, which is half of DF.
By the Pythagorean theorem, we have:
[tex](20/2)^2 + (x/2)^2 = 24^2\\100 + (x/2)^2 = 576\\(x/2)^2 = 476\\x/2 = \sqrt(476)\\x = 2 \times 21.86\\x = 43.72\\x = 44[/tex]
