Without graphing, what are the vertex , axis of symmetry, and transformations of the parent function? Y - |8x-3| - 3
Answers
Given:
Consider the given function is
[tex]y=|8x-3|-3[/tex]
To find:
The vertex , axis of symmetry, and transformations of the parent function?
Solution:
We have,
[tex]y=|8x-3|-3[/tex]
[tex]y=\left|8\left(x-\dfrac{3}{8}\right)\right|-3[/tex]
[tex]y=8\left|x-\dfrac{3}{8}\right|-3[/tex] ...(i)
It is an absolute function.
The vertex form of an absolute function is
[tex]y=a|x-h|+k[/tex] ...(ii)
where, a is a constant, (h,k) is vertex and x=h is axis of symmetry.
From (i) and (ii), we get
[tex]a=8,h=\dfrac{3}{8},k=-3[/tex]
So,
[tex]\text{Vertex}:(h,k)=\left(\dfrac{3}{8},-3\right)[/tex]
[tex]\text{Axis of symmetry}:x=\dfrac{3}{8}[/tex]
Parent function of an absolute function is
[tex]y=|x|[/tex]
Since, a=8 therefore, parent function vertically stretched by factor 8.
[tex]h=\dfrac{3}{8}>0[/tex], so the function shifts [tex]\dfrac{3}{8}[/tex] unit right.
k=-3<0, so the function shifts 3 units down.
Therefore, the vertex is [tex]\left(\dfrac{3}{8},-3\right)[/tex] and Axis of symmetry is [tex]x=\dfrac{3}{8}[/tex]. The parent function vertically stretched by factor 8, shifts [tex]\dfrac{3}{8}[/tex] unit right and 3 units down.

Answer:
The value of the expression when x = -1 and y = 2 is -16.
Step-by-step explanation:
Firstly, let's look at [tex]x^{3}[/tex].
As the question provides, the value of x is -1. Therefore, we have to find the value of [tex](-1)^{3}[/tex], which is -1.
Now, moving onto [tex]y^{2}[/tex].
The question provides us with y = 2. Simply substitute this value into [tex]y^{2}[/tex], and we get [tex]2^{2} = 4[/tex].
Finally, concluding the equation, we get 4(-1)(4). That is equal to -16, which is our answer.

How can you verify trigonometric identities?
Answers
Answer:
Consequently, any trigonometric identity can be written in many ways. To verify the trigonometric identities, we usually start with the more complicated side of the equation and essentially rewrite the expression until it has been transformed into the same expression as the other side of the equation.

A cafeteria starts with 750 fish sticks for lunch. Each meal they serve uses 6 of the fish sticks, At the end of the lunch there are 42 fish sticks left. Let n be the number of meals served in the cafeteria. Set up and solve an equation to find the value of n.
Answers
Answer:
The value of N = 118
Step-by-step explanation:
750 = 6n + 42
move all the numbers that don't contain n to the right side
6n = 750 - 42
6n = 708
708 / 6 = 118
n = 118
plug the numbers back in
6 ( 118) = 708
708 = 708
plug the 42 back in
708 + 42 = 750

The function y = -3x + 42 models the average number of dogs at an animal shelter, where x is the number of days after July 1. The function y = 4x + 7 models the average number of cats at the animal shelter, where x is the number of days after July 1. After how many days is the average number of cats and dogs at the shelter the same?
A. 5 days
B. 7 days
C. 35 days
D. 49 days
Answers
Answer:
A. 5 days
Step-by-step explanation:
Average number of dogs at an animal shelter: y = -3x + 42
Average number of cats at the animal shelter: y = 4x + 7
Where,
x = number of days after July 1
After how many days is the average number of cats and dogs at the shelter the same?
Equate both functions
-3x + 42 = 4x + 7
-3x - 4x = 7 - 42
-7x = -35
Divide both sides by -7
x = -35 / -7
= 5
x = 5 days
The correct answer is A. 5 days

Step-by-step explanation:
Step 1: Define Equation
4x - 8 = 16
Step 2: Solve for x
Add 8 to both sides: 4x = 24Divide 4 on both sides: x = 6Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 4(6) - 8 = 16Multiply: 24 - 8 = 16Subtract: 16 = 16Here we see that 16 does indeed equal 16.
∴ x = 6 is the solution to the equation.

Isaiah gave $18 to his Friends. He gave 4 to Ricardo, $7 to Jeremiah, and the rest to Fabian. how much money did Fabian get?
Answers
Answer:
Fabian got $7.
Step-by-step explanation:
Isaiah gave $18 to his friends--Ricardo got $4, Jeremiah got $7, and Fabian got the rest. This needs a math equation!
4 + 7 + f = 18
where f is the amount of money Fabian got.
4 + 7 + f = 18
(subtract 4 from both sides)
7 + f = 14
(subtract 7 from both sides)
f = 7
It looks like Fabian got $7! Let's check just to make sure.
4 + 7 + f = 18
4 + 7 + (7) = 18
18 = 18
It checks out!
