Determine whether each of the following equations is a function from x to y.
a. y = 2x + 1
b.1 = 2y – 4x
c. y2 – 1 = x
Answer:
a. y = 2x + 1: Not from x to y
b.1 = 2y – 4x: Not from x to y
c. y^2 – 1 = x: This is a function from x to y
Step-by-step explanation:
We are to determine whether or not the equations are function from x to y
Given the function y = f(x)
y is a dependent variable while the input variable is an independent variable. So we can say y is a function from y to x.
Also x = f(y) can be expressed as equation of a function from x to y i.e x is dependent and the input variable is independent
From tthe following options, the equation that is a function from x to y is
y² – 1 = x
This can also be written as x = y² – 1 where f(y) is y² – 1
The rest are not a function of x to y but otherwise unless re-written

A school is arranging a field trip to the zoo. The school spends 698.24 dollars on passes for 29 students and 3 teachers. The school also spends 255.49 dollars on lunch for just the students. How much money was spent on a pass and lunch for each student?
Answer:
30.63
Step-by-step explanation:
698.24 divided by 32. because they counted the teacher and the student passes together. Then you add that number to 255.49 divided by 29 because the teachers pass is not included so then you get youre answer of 30.63
(a) Complete the table of values for y = 1/2x + 1
Please help ❤️
Answer:
y =1, 1.5, 2, 2.5, 3
Step-by-step explanation:
Plug in the values of x into the equation for y.
For example when x is 0, plug in 0 into the equation
0.5x + 1 = y
0.5(0) + 1 = 1
So, y = 1
To find the other values of y, plug in the designated value of x into the equation.

Solve for the missing variable(s) and SHOW ALL WORK
Answer:
x = 4
Step-by-step explanation:
From the picture attached,
By using mean ratio theorem in the given triangle,
[tex]\frac{AC}{BC}=\frac{BC}{CD}[/tex]
AC × CD = (BC)²
(x + 5)x = (x + 2)² [Since, AC = AD + CD]
x² + 5x = x² + 4x + 4
5x = 4x + 4
5x - 4x = 4
x = 4
Therefore, x = 4 will be the answer.

Answer:
[tex]a_3=22[/tex]
Step-by-step explanation:
Given that,
a₁ = 10
[tex]a_n=a_{n-1}+6[/tex]
We can find second term first.
[tex]a_2=a_{2-1}+6\\\\=a_1+6\\\\=10+6\ (Given\ a_1=10)\\\\=16[/tex]
We need to find the third term of the above sequence. Put n = 3 in the above sequence as follows :
[tex]a_3=a_{3-1}+6\\\\=a_2+6[/tex]
Put a₂ = 16
[tex]a_3=16+6\\\\=22[/tex]
Hence, the third term of the sequence is 22.

Draw a point B, then draw any two other points D and E. The rays BD and BE are essentially arrows that both start at B and pass through D and E, respectively. See the attached sketch. Note that the points D and E need not lie on a circle like the dotted one in the sketch; they can be placed anywhere along the ray.
Then:
• (I) is sometimes true. Rays can be parallel as long as they are collinear, meaning the three points B, D, and E would need to lie on the same line. (The first sketch shows one example)
• (II) is always true.
• (III) is sometimes true, if the angle the two rays form is a right angle. (The second sketch shows one example)
• (IV) is never true, because B would have to lie on the circle itself. The center does not.
Without knowing what Damiana's/Valeria's drawing looks like, the most we can do is rule out C and D.

Answer: y=-1/3x+5
Step-by-step explanation: I presume they want this in the y=mx+b format where m is the slope (change in y/change in x) of the line and b is the y-intercept (what y is when x is equal to 0). To answer this you need to choose any 2 points on this graph. For simplicity's sake, I'm going to choose (0,5) and (9,2). What's good about choosing (0,5) is that we now know the y-intercept is 5. Now, to find slope, subtract the y coordinate 2 from the y coordinate 5. You now know that the change in y is 3. Then, subtract the x coordinate 9 from the x coordinate 0. You now know that the change in y is -9. Finally, divide 3 (change in y) by -9 (change in x) and you should get -3/9 which can be simplified into -1/3. So now that you have your y-intercept and your slope, all that's left to do in plug it into the format. So your answer should be y=-1/3x+5. Hope this helps you!
Convert the expression to exponential form
4.4.4.4.4
Answer:
4^5 (the 5 is the exponent)The exponential form of expression is 4⁵.
What is exponential form?To grow at an ever-increasing rate is referred to as exponential growth. On the other hand, it is a mathematical expression with one or more exponents in mathematics. As a result, we call it an exponential form.
We can say that something might grow at an exponential rate if it grows faster and faster as the thing being discussed gets bigger.
Given expression

Writing a number as the product of its prime factors is the very first step in expressing it in exponential form.

△FGH is translated up 2 units to form the image ∆F′G′H′.
What are the coordinates of the vertices of ∆F′G′H′ ?
Enter your answer by filling in the boxes.
F′ = ( , )
G′ = ( , )
H′ = ( , )
Answer:
I hope the Picture Helps!
Step-by-step explanation:
<333
The required coordinates of the vertices of ∆F′G′H′ is F' = (-5, 2), G'= (0, 2), and H' = (0, 6).
What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.
As mentioned in the question, a given triangle on coordinate axes translated 2 units up. The term "2 unit up" implies that each ordinate of the coordinates of the triangle is increased by 2 units,
So the trasformation equation for the triangle is given as,
(x, y) ⇒ (x, y+2)
Now, the coordinates of the vertices of ∆FGH,
F = (-5, 0), G= (0, 0) H = (0, 4)
After the trasformation coordinate of ∆F′G′H′
F' = (-5, 0 + 2), G'= (0, 0 + 2) H' = (0, 4 + 2)
F' = (-5, 2), G'= (0, 2) H' = (0, 6)
Thus, the required coordinates of the vertices of ∆F′G′H′ is F' = (-5, 2), G'= (0, 2), and H' = (0, 6).

Based on the pie chart, the four largest locations for soft drink sales
account for approximately what percentage of total soft drink sales in
the year under consideration?
Answer: 95%
Step-by-step explanation:
With the information provided, the four largest merchants are Grocery Stores, Fountain, Gas Stations, and Vending Stores.
These stores each make up 44%, 24%, 16%, and 11%, respectively.
The sum of these percentages is 95%. Thus, the four largest locations for soft drink sales make up 95% of soft drink sales.
