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.
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

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.

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!
Hope this helps!!

Consequently, any trigonometric identity can be written in many ways.

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
