The Correct choices are :
the dependent variable is y the rate of change is not constant independent variable is x This is a negative relationship The relationship is nonlinearWrite a linear function f with f (5) = 7 and f (-2) = 0
Step-by-step explanation:
Determine points
We can use f (5) = 7 and f (-2) = 0 to write two points.
(5 , 7) & (-2 , 0)
Find Slope
Slope = (y₂ - y₁) ÷ (x₂ - x₁)
= (7 - 0) ÷ (5 - (-2))
= 1
Write the equation
equation in point-slope form (y - y₁) = m (x - x₁)
(y - 0) = 1 (x - (-2))
y = x + 2
Video One, a Blu-ray disc player manufacture, produces two model of Blu-ray players. The mini-blue, which can only play a Blu-ray disc and the media-blue that plays Blu-ray disc and contains a personal DVR. The players are assembled on two different assembly lines. Line 1 can assemble 3 units of the mini-blue model and 13 units of the media-blue model per hours, and Line 2 can assemble 4 units of the mini-blue model and 4 units of the media-blue model per hours. The company needs to produce at least 24 units of the mini-blue model and 64 units of the media-blue model to fill an order.Letx= the number of hours for Line 1Lety= the number of hours for Line 2.Write the system of inequalities≥24≥64Graph the system of inequalities.
The question is an illustration of inequalities and equation.
The system of inequalities are: [tex]\mathbf{3x + 4y \ge 24}[/tex] and [tex]\mathbf{13x + 4y = 64}[/tex]
Represent the number of hours for lines 1 and 2 with x and y.
So, we have:
Minibus
Line 1 = 3
Line 2 = 4
Total: At least 24
Media-blue
Line 1 = 13
Line 2 = 4
Total = 64
At least means greater than or equal to.

Part A
x = amount of money she starts with
(4/9)x = cost of the dress
(5/9)x = amount of money leftover after buying the dress
note that 4/9 and 5/9 add to 1 to represent 100% of her money
(3/4)*(5/9)x = (15/36)x = (5/12)x = amount spent on shoes
We see that she spent 5/12 of her original amount of money on shoes.
-----------------------
We can look at a more concrete example if the previous section does not make sense.
Let's multiply the denominators 9 and 4 to get 9*4 = 36. Doing this trick will mean that the later steps won't involve decimal values.
Let's say she starts off with $36
Multiply that with 4/9 to get (4/9)*36 = 16. So in this hypothetical situation, the dress costs $16 and she's left with 36-16 = 20 dollars.
Multiply that 20 by 3/4 to get (3/4)*20 = 15
In this situation, the shoes cost $15
We'll then divide the cost of the shoes (15) over the original amount of money she started with (36)
15/36 = (3*5)/(3*12) = 5/12
-----------------------
Answer: 5/12=======================================================
Part B
From the first section in part A, we found that:
(4/9)x = amount of money spent on the dress(5/12)x = amount of money spent on shoesAdd those two expressions
(4/9)x + (5/12)x = (16/36)x + (15/36)x = (31/36)x
This indicates that buying the dress and shoes will cost (31/36)x dollars, where x is the original amount of money Jing has to start with.
The amount left over is (5/36)x because 5/36 adds with 31/36 to get 1.
Take 1/3 of this to get:
(1/3)*(5/36)x = (5/108)x
Then set this equal to 18 and solve for x
(5/108)x = 18
5x = 18*108
5x = 1944
x = 1944/5
x = 388.80
--------------------
Let's check the answer
If she starts with 388.80 dollars, then the dress costs (4/9)*388.80 = 172.80
She's left with 388.80 - 172.80 = 216 dollars after buying the dress.
She then spends the remaining 3/4 of that on shoes. So (3/4)*216 = 162 dollars is spent on the shoes.
Jing now has 216 - 162 = 54 dollars left over.
1/3 of which is spent on the shoe bag, meaning it costs (1/3)*54 = 18 dollars
This confirms our answer.

Can someone tell me the answer and explain it please
Answer:
x^2 - y^2
Step-by-step explanation:
In the following problem, we can use the distributive property to simplify:
(x + y)(x - y)
We can start by multiplying the x's together, giving us x^2.
Next is the first x multiplied by -y in the second parenthesis. This gives us -xy.
Now, we can move on the the y in the first parenthesis: y times x(in the second parenthesis) is xy.
Lastly, we have y times -y which gives us -y^2.
(This process is shown in the image attached)
If we aa these together we get:
x^2 - xy + xy - y^2
If we add -xy and xy it would be 0 because if you add a number with it's opposite, they cancel out. We are just left with x^2 - y^2.

Answer 45^(1/2)
Step-by-step explanation:
Use the pythagorean theorem to calculate the distance of the hypotenuse formed by the two siz=des that can be calculated from the given 2 points. X is 3: (-2 -(-5)) = 3
y is 6: (9-3) = 6
We want the hypotenuse: z^2 = x^2 + y^2
z^2 = 9 + 36
z = [tex]\sqrt45}[/tex]
It asks for the exact answer, so 45^(1/2) sems to be the only way to express this.
Use the diagram shown to answer the question. What are the sine and cosine values of a 60° angle?
Answer:
The answer would be A.
Step-by-step explanation:
Consider the graphs of j(x) = = 7 sin (6x- pi/2) +11 and k(x) = 7 sin(6x- pi/2) - 11. Which feature of the graph of k(x) is different from the graph of j(x)?
Answer: the vertical shift
Step-by-step explanation:
The vertical shift because the first equation j(x) is shifted up 11 while k(x) is shifted down 11. D in the equation y=acos/sin(bx-c)+d indicates if an object is moving vertically up or down.
The graph of k(x) have Vertical shifted down and graph of j(x) Vertical shifted up 11.
What is Translation?Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.
For example, this transformation moves the parallelogram to the right 5 units and up 3 units. It is written ( x , y ) → ( x + 5 , y + 3 ) .
Given:
j(x) = = 7 sin (6x- pi/2) +11
k(x) = 7 sin(6x- pi/2) - 11.
The +11 in j(x) shows the Vertical shift up.
and, the '-11' in k(x) shows the Vertical shifted down 11.
Hence, the difference is of the vertical shifting up or down.
