What is a graph?
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
In the first and the fourth graph the function follows a curved graph because of it, it does not follow linearity. In the second and third graphs, the function follows a linear line, therefore, it shows a constant rate of change.

-three: collect like terms
3x + 24 = 2x + 10

what is the area of this parallelogram 74.20 meters squared 154.50 meters squared 227.63 meters squared or 331.50 meters squared
Answers
Answer:
227.63 meters^2
Step-by-step explanation:
The formula to find an area of a parallelogram is a = bh (base multiplied by height). According to the figure, the base is 22.1 meters and the height is 10.3 meters.
a = bh
a = 22.1(10.3)
a = 227.63 meters^2

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

1. What is a formula that can be used to find the area of one triangular section of the door?
2. How do you know the formula will work?
Answers
Answer:
\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)
Step-by-step explanation:
Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.
\(A = \frac{h_{b}+b}{2}\)
Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.
By using trigonometric relations we will see that the area is:
How to find the area of one triangular section?
Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.
Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).
h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:
tan(60°) = x/h
x = tan(60°)*h
Then our two catheti are h and tan(60°)*h.
This means that the area will be:
Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

Answers
Answer:
Step-by-step explanation:
We use a for Adult and s for Student.
Assuming this, you have to start by writing two equations from the information provided:
900 total tickets were sold
a+s=900 ------(i)
they made $2,820 and adult tickets cost $4 and kids tickets cost $2.50
2820=4a+2.5s ------(ii)
lets solve for a in the first equation:
a=900-s
we can plug this into the second equation and solve for s
2820=4(900-s)+2.5s
2820=3600-4s+2.5s
2820=3600-1.5s
-780=-1.5s
s=520
we can plug this into the first equation and solve for a:
a+520=900
a=380
Total adult ticket sold : 380
Total student ticket sold = 520
Cost of adult tickets = 380 * 4 = $1520
Cost of student tickets = 520 * 2.5 = $1300

C. Yes, since each output (cost in dollars) has a single input (time in hours)
D. Yes, since each input (time in hours) has a single output (cost in dollars)
Answers
Answer:
No, since there are two inputs (time in hours) which have the same cost (in dollars). Therefore, option A is the correct answer.
Explanation:
What is the function?
Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
From the given that,
(1, 25), (2, 45), (3, 45) and (4, 55)
It is not a function as two inputs 2 and 3 has a single output 45.
That means A is correct, i hope you have a good day random person :)
