hi please help im giving full points and brainliest:) Let y = 2(x – 3)2 – 6.
Part A: Is the given relation a function? Is it one-to-one? Explain completely. If it is not one-to-one, determine a possible restriction on the domain such that the relation is one-to-one. (5 points)
Part B: Determine y–1. Show all necessary calculations. (5 points)
Part C: Prove algebraically that y and y–1 are inverse functions. (5 points)
Answer/Step-by-step explanation:
Part A:
Yes, the given relation is a function
No, the given is not one-to-one.
The given relation is a function: True
The given one-to-one function: False
For the domain (3, + ∝) or the domain (- ∝,3)
the relation is one-to-one.
Part B:
[tex]y=2(x-3)^2-6[/tex]
[tex]y+6=2(x-3)[/tex]
[tex](x-2)^1=\frac{y}{2}+3[/tex]
[tex]x-2=[/tex] ±[tex]\sqrt{\frac{y}{2}+3}[/tex]
[tex]x=[/tex] ± [tex]\sqrt{\frac{y}{2}+2+2}[/tex]
So, [tex]y^-^1=[/tex] ± [tex]\sqrt{\frac{x}{2}+3}+3[/tex]
Part C:
[tex]y(y^-^1)=2([/tex]±[tex]\sqrt{\frac{x}{1}+3+3-3)^2-6}[/tex]
[tex]=2(\frac{x}{2}+3)-6[/tex]
[tex]x+6-6=x[/tex]
So y and y^-^1 are inverse function.

Y-2 = 7(X-4), what form of an equation is this?
Is this in correct standard form? Why or Why not
9514 1404 393
Answer:
point-slope formno -- not in standard formStep-by-step explanation:
The point-slope form of the equation for a line with slope m through point (h, k) is ...
y -k = m(x -h)
Comparing this to the equation you have, you see that you have a "point-slope form" equation with m=7 and (h, k) = (4, 2).
__
The standard form of an equation for a line is ...
ax +by = c
where a, b, c are mutually prime integers and a > 0.
Putting your equation into standard form would make it look like ...
7x - y = 26
Your equation is not in correct standard form.

The variables y and x have a proportiurial relationship, and y = 28 when x = 21.
What is the value of x when y = 42?
x= 14
x = 18 2/3
x= 31 1/2
x=56
Answer:
x = 31 1/2
Step-by-step explanation:
If y = 42, that means the original y = 28 was multiplied by 1.5, so we have to multiply x = 21 by 1.5 to find the answer.
21 * 1.5 = 31.5 A.K.A 31 1/2
Simone wrote that 2+5.8=6.
Use the drop-down menus to explain why 6 is incorrect.
2+5.8 cannot be 6 because 2+5.8 is
Six is a correct sum to the expression +5.8, not 2+5.8.
Answer: The correct equation should be 0.2+5.8=6
Step-by-step explanation: First of all let's look at the equation without the decimal ".8". So, it would be 2+5 which equals 7. Since the sum is greater, adding a decimal will make the sum larger than 6. 2+5.8=7.8, therefore the correct equation being 0.2+5.8=6. Hopes this makes sense and helps!

Answer:
A
Step-by-step explanation:
Since cosine is positive and sine is negative that puts θ in Quad IV.
From right triangles we know:
Cos θ = adjacent/hypotenuse = 5/13
sin θ = opposite/hypotenuse = ?/13
To find the opposite side across from θ use the pythagorean theorem.
5² + y² = 13²
25 + y² = 169
y² = 144
y = 12
we are given that sin is < 0 so sinθ = -12/13
Answer:
A
Step-by-step explanation:
[tex]\cos(\theta)=\dfrac{\textsf{adjacent side}}{\textsf{hypotenuse}}=\dfrac{5}{13}[/tex]
[tex]\textsf{As }\cos(\theta) > 0 \textsf{ the angle is in quadrant I or IV}[/tex]
Using Pythagoras' Theorem a² + b² = c² to find the side opposite the angle:
⇒ 5² + b² = 13²
⇒ b² = 144
⇒ b = 12
⇒ opposite side = 12
[tex]\implies \sin(\theta)=\dfrac{\textsf{opposite side}}{\textsf{hypotenuse}}=\dfrac{12}{13}[/tex]
[tex]\textsf{As }\sin(\theta) < 0 \textsf{ then }\sin(\theta)=-\dfrac{12}{13} \textsf{ and the angle is in either quadrant III or quadrant IV}[/tex]
Therefore, the common quadrant is quadrant IV and
[tex]\sin(\theta)=-\dfrac{12}{13}[/tex]
Zendaya needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 4.25 hours and charged her $59 for parts. The total was $377.75. What was the cost of labor, per hour?
This is oddly the funniest question I've seen so far. But never fear, I guess I'm here? :\
Honestly, I'm kinda lost but your answer should be $88.88. Even though it would say $88.88 multiplied by total hours, which is 4 hours and 25 minutes is $377.74, that answer is determined by a thousandth of a number. If you want it the other way, it's 88.8824.
Definitely hope this helped. [Pretty much, the answer is $88.88.]
The cost of labor per hour is $75.
It is required to find the cost of labor per hour.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
The total amount that the technician charged her is the sum of the cost for the total hours worked and the costs of the parts.
Total charge = cost of total hours worked + cost of parts
$377.75 = $59 + cost of total hours worked
Cost of total hours worked = $377.75 - $59
Cost of total hours worked = $318.75
In order to determine the cost per hour of labor, divide the total cost of total hours worked by the hours worked.
$318.75 / 4.25 = $75.
Therefore, the cost of labor per hour is $75.

Solution:
We know that:
Interior angles of a triangle sum up to 180°.[tex]3a + 7u + 9 = 180\°[/tex]This means that:
[tex](7u + 9) + (2a - 3) + 32 = 3a + 7u + 9[/tex]Let's simplify the equation to find a.
Step-by step calculations:
Open the brackets:
[tex](7u + 9) + (2a - 3) + 32 = 3a + 7u + 9[/tex][tex]7u + 9 + 2a - 3 + 32 = 3a + 7u + 9[/tex]Cancel same terms on both sides:
[tex]7u + 9 + 2a - 3 + 32 = 3a + 7u + 9[/tex][tex]2a - 3 + 32 = 3a[/tex]Simplify the LHS:
[tex]2a + 29 = 3a[/tex]Subtract 2a both sides:
[tex]2a - 2a + 29 = 3a - 2a[/tex]=> [tex]29 = 3a - 2a[/tex]Simplify the RHS and change the sides:
=> [tex]\bold{a = 29}[/tex]Let's substitute the value of a in 3a + 7u + 9 = 180° to find u.
[tex]3a + 7u + 9 = 180\°[/tex]=> [tex]3(29) + 7u + 9 = 180\°[/tex]Simplify the LHS:
=> [tex]87 + 9 + 7u = 180[/tex]=> [tex]96 + 7u = 180[/tex]Subtract 96 both sides:
=> [tex]96 - 96 + 7u = 180 - 96[/tex]=> [tex]7u = 84[/tex]Divide 7 both sides:
=> [tex]\frac{7u}{7} = \frac{84}{7}[/tex]=> [tex]\bold{u = 12}[/tex]4。
